Connection method
The assembly of the trunking units – even with the end caps and feeder units – is fast and
inherently safe. The trunking units or end caps are simply inserted into the lower housing of
the joint block. Once the upper part of the joint block or end cap is fitted, a secure connection
is established by simply tightening the 4 screws.
Figure 1-3 Establishing a safe connection
Tap-off units
Tap-off units are available in four different sizes to connect the loads and also with various
components fitted, e.g. such as plugs, fuses, miniature circuit breakers or combinations of
the aforementioned.
Figure 1-4 Tap-off unit BD01 system
Ancillary equipment units offer additional space for decentral function expansions. Thus,
automation and control components can be installed directly on the busbar.

SIVACON 8PS - Planning with SIVACON 8PS
Planning Manual, 11/2016, A5E01541101-04 17
Fixing and mounting
The BD01 busbar is installed edgewise, with the tap-off points on the side using fixing
brackets on the wall, ceiling or non-fixed installation. The mounting is implemented on the
connection points using a universal fixing bracket. The system can also be fitted flat with the
tap-off points pointing downwards. This reduces the required fixing interval by half.
Figure 1-5 Fixing the BD01 system
Fire protection
If the busbar trunking system is routed through a fire wall or ceiling, it must have fire
protection. Compliant with site requirements, Siemens offers fire protection class S90.
(EI90 available soon)
Ex-works equipment:
● External fire protection in the form of a kit for on-site mounting
Mineral mortar or fire protection mastic to seal the joints between busbar trunking system
and component must be provided by the customer.
Figure 1-6 Fire protection BD01-S90
The approval documentation for Germany can be ordered separately:
● Approval kit BD01-S90-ZUL-D
(approval certificate, wall signage and declaration of compliance)

Networked busbar trunking systems for industrial and building
applications
The advantages of busbar trunking systems
The busbar trunking system has its advantages in the transport, distribution as well as
switching and protection of electrical energy.
Integration of automation and building systems engineering into the Siemens busbar trunking

Structure of the planning manual
It is not by any means easy to plan a power distribution concept involving the dimensioning
of systems and devices. End user requirements have to be matched with the technical
capabilities of the manufacturer. This planning manual will provide assistance as you plan
and design the following busbar trunking systems from 160 A to 6300 A:
● BD2
● LD
● LI
● LR
Description of the individual systems
Each system has a dedicated chapter describing its technical characteristics and areas of
application. Illustrations of the individual busbar trunking system elements also appear. All
significant information relevant to the planning process is given particular emphasis and
explained in detail.
Further information
You will find advice to help you to develop a ready-to-use planning solution under "Further
information". These include specific dimensioning principles and detailed information about
topics such as fireproof barriers and functional endurance.
Siemens can offer a range of services and engineering tools to assist you in drafting your
specification. For an overview and explanation of functions and features, please see Tools
and services (Page 307).

Principles of busbar trunking system planning
Decision-making criteria affecting the creation of the power supply concept
When drafting a planning concept for a power supply, in addition to the applicable standards
and regulations, you also need to clarify and address issues of cost and technology.
Accordingly, when dimensioning and selecting electrical equipment such as distribution
boards and transformers, rather than focussing on them individually, you need to aim to
optimise their performance as part of a combined system.
All components have to be dimensioned sufficiently for loads both in rated operation and in
the event of a malfunction. Furthermore, you must take the following important issues into
consideration when drafting a power supply concept:
● Building type, use and design (e.g. high rise, low rise or number of storeys)
● Determination of load centres, identification of possible supply routes and locations for
transformers and main distribution boards
● Calculation of the building's effective installed loads according to specific area loads as
appropriate for the building's use
● Planning authority regulations and requirements
● Requirements set out by the utility company
Requirements to be met by power supply concepts
Planning will never produce just a single option for a solution. Rather, you will need to
assess a number of possible options on the basis of issues relating to technology and cost.
The following requirements are major factors:
● Simple and transparent planning
● Long service life
● High availability
● Low fire load
● Flexible adaptation to changes in the building

The solution: Siemens busbar trunking systems
In most applications, these requirements can easily be solved by using suitable busbar
trunking systems.
It is for this reason that busbar trunking systems are increasingly being preferred to cable
trunking by engineering consultants charged with designing systems for power transmission
and distribution. Siemens offers busbar trunking systems from 40 to 6300 A:
● The BD01 busbar trunking system from 40 to 160 A for supplying power to shopfloors
with tap-offs up to 63 A
● The BD2 system from 160 to 1250 A for supplying power to medium-sized consumers in
building and industrial applications
● The ventilated LD system for supplying power to consumers with medium power
requirements in industrial applications
● The LI sandwich system for power distribution to consumers with high power
requirements in building applications
● The LR cast resin system for power transmission under extreme ambient conditions
(IP68)

2.2.2
Different types of busbar trunking systems and their functional scope
Requirements of the power supply
Specific requirements of power supplies and their individual components are typical of
modern production facilities and in building technology today. This is particularly true of
automated facilities.
The ability to retrofit new equipment or modify existing resources without interrupting active
production is not only important for the continuous provision of the electrical power supply. It
is also a vital requirement for production facilities operating on a multiple shift basis.
Increased safety and complex systems require a power distribution system which is able to
respond to all requirements associated with costs and technology.
The BD01, BD2, LD, LI and LR busbar trunking systems are type-tested low-voltage
switchgear assemblies in accordance with IEC / EN 61439-1 and -6.
The BD01, BD2 and LD systems consist of busbars, internal bar fixings, an external
enclosure, fixing and connection accessories. The LI sandwich system and the LR cast resin
system consist of busbars, fixing and connection accessories and an insulating foil, along
with an aluminium enclosure (LI ) or an enclosure made from epoxy resin (LR).
Figure 2-2 BD2 trunking unit with tap-off unit
Power transmission
Components of the busbar trunking system transmit power between transformers and low
voltage power distribution systems and from the main distribution board to the service
distribution board. Trunking units without tap-off points are used for the power transmission.
In addition to the standard lengths, customers can select any lengths to meet their particular
building requirements.

2.2 Busbar trunking system planning
SIVACON 8PS - Planning with SIVACON 8PS
Planning Manual, 11/2016, A5E01541101-04 23
Power distribution
The main application of busbar trunking systems is power distribution. Current can't be taken
from just a single point which is permanently installed such as a cable installation. Current
tap-off units can be moved to any position within the entire system. To tap power at any
given point simply requires positioning a tap-off unit at that location on the busbar.
The result is a flexible distribution system for decentralised power supply to a particular line
or area. Tap-off points can be mounted on one or both sides of straight trunking units.
Depending on the requirements of the particular application, busbar trunking units with tap-
off units for a rated current of 1250 A from a single tap-off point are available for tapping off
power and connecting loads. The tap-off units can be equipped with fuses, fuse-switches,
miniature circuit breakers or circuit breakers as desired.
To be able to change the tap-off units without disconnecting the busbar trunking run, the
following
requirements
apply:
● The PE contact on the tap-off unit leads during installation and lags during removal.
● The parts which are live during installation, removal or connection have complete
protection against direct contact (degree of protection IP2x).
● Installation requires phasing to be correct.
● The tap-off unit must be isolated during installation and removal.

Centrally in the distribution board: this means
that assignment to the load cannot be veri-
fied directly. You have to rely on the cable
and load being labelled correctly.
Space requirements Low High, since correspondingly large distribution
boards are needed. Laying criteria (cluster-
ing, laying method, current carrying capacity,
etc.) have to be taken into account
Retrofitting in the event of
changes to load feeders
Highly flexible thanks to tap-off points in

Planning made easier
Easy to plan, quick to install and flexible to use: Siemens busbar trunking systems are an
efficient means of supplying power to any building. Power distribution can be planned
precisely on the basis of total connected load and the type and number of loads. Planning
tools such as SIMARIS design provide assistance. The line topology with load feeders
arranged at regular intervals ensures transparency. All applications can be implemented
quickly and compactly with standardised sizes.
In a cable trunking system, new loads have to
be connected via an additional sub
-
distribution
board; this costs both time and money.
On busbar trunking systems, tap
-off units in
the vicinity of loads ensure local transparency.
Increased safety due to high short-circuit rating and minimum fire load.
Advanced safety – both in respect of short-circuit rating and where fire load is concerned.
BD2A 250 busbar trunking systems, for example, have a fire load of just 1.32 kWh/m,
whereas comparable cable trunking systems (NYY 4 x 95 / 50 mm2) are rated at
5.19 kWh/m. The busbars are also halogen-free. Siemens busbar trunking systems feature
high short-circuit rating. Furthermore, troubleshooting is made easier thanks to local load
short-circuit protection.

Selection on the basis of rated transformer data
Figure 2-4 Connection of a transformer to a Siemens power distribution board
The table can be used to select the appropriate busbar trunking system on the basis of the
transformer's rated current. The short-circuit rating of the LD, LI and LR busbar trunking
systems is usually higher than the values for the transformer's sustained and peak short-
circuit currents. However, this only applies if just a single transformer is used for the low-
voltage supply. Higher short-circuit values are possible on ring or meshed networks or if
transformers are connected in parallel in a low-voltage switchgear assembly. Such scenarios
must therefore be given special consideration. Please refer to the technical data for the
busbar trunking systems in question for specific data about short-circuit ratings.

The BD2 busbar trunking system is suitable for universal use. Designed for applications
involving flexible power supplies and power distribution for consumers in industrial and
commercial environments, it can also be used to transmit power from one supply point to
another. In addition, the BD2 busbar trunking system can be used as a rising main busbar in
high rise buildings.

System components
3.2.1
Preliminary remark for specifications
The BD2 busbar trunking systems are to be offered as type-tested low-voltage switchgear
assemblies in accordance with IEC / EN 61439-1 and -6.
The brand offered represents a complete system consisting of system modules, including
elements for connection to the distribution boards such as brackets, straight trunking units,
e.g. Z connectors, T connectors, and flexible junction units.
Trunking units with tap-off openings can be equipped with coded tap-off units. Tap-off units
are protected against incorrect mounting. Depending on the type, the isolation of the tap-off
units during removal is assured by a compulsory sequence of operations or by cautionary
instructions.
If necessary, it is possible to equip the busbar trunking system with an asbestos-free fire
barrier which conforms in the case of BD2C to the fire resistance class S120 and in the case
of BD2A to S90 or S120 (EI90 and EI120 available soon). The trunking unit's steel enclosure
is made of moulded steel profiles to permit large fixing distances between suspension points.
The enclosure is painted in a light grey colour (RAL 7035).
The external dimensions may not exceed 68 x 167 mm up to 400 A or 126 x 167 mm up to
1250 A. The connection of the individual systemmodules is implemented with state-of-the-art
quick connection terminals with integral compensation for expansion. The system is
protected against phase inversion. A mechanical, electrical and maintenance-free
connection between two busbar trunking system elements can be established quickly and
safely using conventional tools.
The conductors are made of aluminium or copper. The aluminium and copper conductors
must be nickel-plated and tinned along their entire length. The fire load should not exceed
the value stated in the technical specifications. Expansion compensation must be integrated
into eachtrunking unit. Busbar trunking units should be able to be mounted both horizontally
and vertically. Junction units may not be used to connect cables.. Flexible junction unit are
permissible as system modules of the busbar trunking system.
The following declarations of conformity must be included with the offer:
● EN ISO 9001 QA certification
● Certificates verifying
– That the fire barrier has been tested and approved
– That functional endurance has been tested and approved

Note
The innovative design and
construction of the BD2 busbar trunking system means that
additional compensation units to compensate busbar expansion are not required. Prevailing
length expansion caused by current heat is compensated in the quick connection terminal.
Furthermore, regard
less of mounting position and degree of protection, the BD2 busbar
trunking system can always be loaded at 100 % of rated current. This only has to be reduced
in the case of pure power transmission in the edgewise mounting position (to 0.9 x

Feeder units
Feeder units are used to feed power into the busbar trunking system with single-core or
multi-core cables as well as to feed power directly to low-voltage distribution equipment. The
incoming supply can be set up as an end feed or a centre feed.
3.2.5.1
End feeder units
Common features
All end feeder units have the following common features:
Cables can be fed in from the front end. Units with cable compartments support cable entry
from the side. In the case of multi-core conductor entry, a sectional entry flange with cable
sleeves and cable propping bar is standard; in the case of single-core conductor entry, an
aluminium plate is standard. The cables are connected using lugs and bolts. The bolts are
supplied with the unit. When connecting 5-conductor cables you will need to remove the
bridge between PE and N which will have been fitted prior to delivery. The phasing can be
changed locally.

Important planning information:
A centre feed might be the best option for the distribution of high powers with small busbar
cross sections. It is mounted in the centre of a trunking run between two trunking units. A
single power supply cable provides power to the left-hand and right-hand trunking runs
simultaneously. This means, for example, that a 1000 A centre feed can feed in 2000 A. In
such cases you need to pay particular attention to the busbar system's overload and short-
circuit protection.
You will need to provide protective measures in the following instances:
● If short-circuit protection is not provided by the upstream protective device and/or
● If the overload is not set by the type and number of loads.
There are two possible protective measures:
1. Use a centre feed unit with one coupling unit on the left of the incoming feeder and
another on the right. The coupling unit is fitted with a protective device (fuse or circuit
breaker) providing short-circuit and overload protection.
2. Use two end feeder units located in the centre of the trunking run. The two supply lines
are fused separately in the distribution system.

Coupling units
Features of coupling units
Coupling units are used if devices or sections of the power supply need to be disconnected
or connected accordingly. To adapt the busbar trunking system to the actual load, the busbar
cross section can be reduced and protected against short circuits and overloads with a
coupling unit.
Coupling units can be fitted with load disconnect switches up to 630 A or circuit-breakers up
to 1250 A as appropriate for the application concerned.
The maximum installation length in the busbar trunking run is 1500 mm. The dimensions of
the coupling unit must not exceed 1250 x 500 x 500 mm (W x H x D).

Important planning guideline
It is not the case that every tap-off unit has a rated voltage of 690 V and a short-circuit rating
in accordance with the system size.
The tap-off units used must be compatible with the values required by the equipment as far
as their short-circuit rating and rated voltage are concerned.
If the tap-off unit is not compatible with the rated voltage, a unit with appropriate internal
components must be selected. Higher short-circuit currents must be limited by means of
upstream protection devices (e.g. circuit breakers).

106 Planning Manual, 11/2016, A5E01541101-04
The LD busbar trunking system is used for both power transmission and distribution. The
system offers a high short-circuit rating and is particularly suited for the connection of
transformers to low-voltage main distribution boards and sub-distribution boards.
In applications where high powers are required, conventional systems frequently require the
use of parallel cables. The LD system offers optimal power distribution for both horizontal
and vertical busbar runs. Coded plug-in tap-off units up to 1250 A that meet extremely high
safety standards are available for this purpose.
4.2
System components
4.2.1
Preliminary technical descriptions for specifications
The busbar trunking systems are to be offered as type-tested low-voltage switchgear
assemblies in accordance with IEC / EN 61439-1 and -6, and as sheet-steel-enclosed ready-
to-use distribution boards.
The distribution systems must be suitable forpower transmission, e.g. between transformer
and low-voltage main distribution boards, as well as for power distribution providing a supply
of power to an entire area.
The brand offered must be a complete system consisting of system modules, including
transformers and elements for connection to the distribution boards, as well as such as
brackets, straight trunking units and junction units. All components should be available both
in straight and offset versions.
Trunking units with tap-off openings should be able to be equipped with coded tap-off units.
Tap-off units are protected against incorrect mounting. Depending on the type, the isolation
of the tap-off units during removal is assured by a compulsory sequence of operations or by
cautionary instructions.
If required, the busbar trunking system should be capable of being equipped with asbestos-
free fire barriers which comply with fire resistance class S120 (EI120 available soon), and
which have been certified by the local or government authority responsible for building
standards. The trunking unit's steel enclosure is made of moulded steel profiles to permit
large fixing distances between suspension points. The enclosure is galvanised and painted
in a light grey colour (RAL 7035).
The external dimensions may not exceed 180 x 180 (240) mm.
The individual system modules are connected by hanging a hook from a bolt and tightening
a state-of-the-art maintenance-free single-bolt clamp. The conductor between two system
units should not be connected with screws.
The conductor material is made of aluminium or of copper if the rated current requires. The
aluminium conductor must be nickel-plated and tinned, and the copper conductor must be
tinned and provided with an additional insulating layer of epoxy-resin.
The fire load must not exceed the value specified in the technical data. Junction units with
flexible connections or cable connections are not permitted.

The following certificates or declarations of conformity must accompany the offer:
● DIN ISO 9001 QA certification
● Proof of sprinkler testing
● Proof of prevention of propagation of an arcing fault
● Proof that the system is maintenance-free

Important planning information
The nominal mounting position of the busbar trunking system is horizontal and edgewise for
the busbars. In very rare cases, due to a specific trunking run or the option of connecting
tap-off units on the side, the busbars might have to be laid flat. The resulting increase in the
internal heat rise of the system necessitates a reduction in rated current. The same applies
to vertical height rises > 1.3 m (see the table in the chapter "Type code (Page 108)").
The LD busbar trunking system is a ventilated system. When the degree of protection is
increased from IP34 to IP54 (enclosed system), the rated current must be derated as
specified in the tables in the next chapter.
4.2.2
Type code
Definition of the required system using the type code
The basic components of the LD system are determined using a type code. The type is
specified and selected on the basis of rated current, conductor material, system type and
degree of protection.
The resulting type code enables the required system to be precisely defined.

Selection example
A rated current of 2500 A is calculated for a project. Aluminium conductors shall be used. A
4-pole system also has to be used. The cross section of the protective conductor needs to
be equal to the cross section of the phase conductor. The required degree of protection is
IP34. The mounting position is horizontal, edgewise, without height rises. Use of the above
table results in the selection of the following type:

LD busbar systems are available with aluminium (LDA....) and also copper (LDC....)
conductor materials. Due to the conductors’ special surface finishing, trunking units with
different conductor materials can be combined. In addition to tinning, aluminium bars are
also coated with a layer of nickel.

Note
Expansion compensation
Due to heat dissipation at rated load, the busbars in the trunking unit expand. To
compensate this expansion in length, you need to include expansion compensation units at
defined
intervals when planning your horizontal installation.
With trunking units for vertical installation, the expansion compensation is integrated.
When planning horizontal busbar runs, please remember:
•
A straight trunking run without expansion compensation between two junction units must
not exceed 10 m in length.
•
A straight trunking run between a junction unit and the end cap must not exceed 25 m in
length. In the case of longer trunking run lengths, planning provision has to be made
accordingly for expansion compensation units.

Tap-off points
Tap-off points are only possible on straight trunking units (both standard lengths and optional
lengths possible). Options are:
● Tap-off points at the TOP: ...-AD
● Tap-off points at the BOTTOM: ...-ADU
● Tap-off points at the TOP and BOTTOM: ...-ADO+U
With a trunking unit with a tap-off point at the TOP and BOTTOM, only one tap-off unit can
be used at a time. The required distance between tap-off points is 1 m.
The required type should be determined during engineering, based on the mounting position
of the busbar.
In the case of optional trunking units with tap-off point, a minimum clearance of 0.6 m is
required between the end of the busbar and a tap-off point.
A coding bracket is located on both sides of a tap-off point. This guarantees non-
interchangeability and correct phasing sequence installation of the tap-off units.

Busbar connection unit for non-Siemens distribution boards
If you wish to connect the busbar trunking system to a non-Siemens distribution board, you
can establish this connection using an LD. .... - FA1 connection unit for non-Siemens
distribution boards. The connection unit is built into the distribution board and serves as an
interface to the copper connections of the distribution system.
Rated currents
● The maximum rated currents are listed in the chapter "Technical specifications
(Page 128)".
● The temperature limit of busbars coated with insulating materials is 135 °C.
● You can find possible conductor cross-sections for the copper connections in the chapter
"Technical specifications (Page 128)".
Installation of the busbar connection unit
The busbar connection unit in the distribution board must be copper-plated by the board
manufacturer or in compliance with that manufacturer's specifications. The board
manufacturer must ensure that the required short-circuit strength is achieved and the
permissible temperature limit of the busbar connection unit for non-Siemens distribution
boards is not exceeded.

Coupling units
Coupling units are used if devices or sections of the power supply need to be disconnected
or connected accordingly. To adapt the busbar trunking system to the actual load, the busbar
cross section can be reduced and protected against short circuits and overloads with a
coupling unit.
Coupling units can be fitted with switch disconnectors or circuit breakers as appropriate for
their application. Coupling units resistant to accidental arcs can be supplied as an option.

Tap-off units
4.2.11.1
Tap-off units
Tap-off for different current ratings
Tap-offs for different current ratings are required, depending on the application and type and
size of loads. These tap-offs are implemented in the form of tap-off units with fuse switch-
disconnectors or with circuit breakers.
There are basically two types of tap-off unit:
● With fuse switch disconnector
● With circuit breaker
Figure 4-11 Tap-off unit with fuse switch disconnector and trunking unit with tap-off point
Early-make PE/PEN
The current tap in the tap-off unit is implemented as an early-make (mounting) or late-break
(removal) PE/PEN conductor contact.
In a 4-conductor system, this is ensured by a longer PEN bar at the contact mechanism. In a
5-conductor system the PE connection is established via grinding contacts on the coding
brackets.
Anti-rotation feature and non-interchangeability
The coding brackets on the tap-off unit and on the trunking unit's tap-off point (lock-and-key
principle) ensure:
● Non-interchangeability and correct assignment of 4 or 5-pole tap-off units to the
associated LD systems
● Anti-rotation feature to prevent incorrect mounting of the tap-off units on the tap-off points

Depending on the current level, LV HRC fuses size NH 00, NH 1, NH 2 or NH 3 are used.
The compact dimensions mean that only one enclosure size is required for all rated current
ranges.
Operator control
The tap-off units with fuse switch disconnector are operated by hand using a swivel
mechanism.
Degree of protection
The standard degree of protection is IP30. IP54 degree of protection can be provided as an
option.

Cable compartment / cable entry
A bolted connection is used for cables with cross sections up to 2 x 240 mm2. In the
standard version, the cable entry is on the front face. Adding a cable compartment enables
cable entry from the side. The cables are routed via an integrated cable propping bar in the
tap-off unit (cleats to be provided by the customer). The sectional flange plate facilitates the
laying of the cables.
Opening the tap-off unit
Do not open the cable compartment cover until you have removed the fuse switch
disconnector handle and, consequently, the fuse. This will ensure that the cable
compartment is voltage-free when the cover is removed. The part of the contact device in the
front of the tap-off unit is "finger-proof".

160 Planning Manual, 11/2016, A5E01541101-04
The LI busbar trunking system is used for:
● Power transmission
● Power distribution
The system is characterised by a high degree of flexibility as it is not tied to a specific
position and is particularly suitable for power distribution in multi-storey buildings. The high
degree of protection up to IP55 and tap-off units up to 1250 A ensure reliable power supply
in industrial applications with high power requirements.
5.2
System components
5.2.1
Preliminary technical descriptions for specifications
Basic description busbar trunking systems 800 A to 6300 A
Busbar trunking systems shall be supplied and installed as type-tested and ready-to-use low-
voltage switchgear assemblies in accordance with IEC / EN 61439-1 and -6.
The following descriptions are part of the costing and contracts process. They must be
considered when specifying individual systems and equipment, even if they are not
subsequently referred to in more detail.
The busbar trunking systems must be suitable:
● For power transmission, e.g. between transformer and low-voltage main distribution
board.
● For power distribution supplying an entire area
● For horizontal and vertical installation
The busbar trunking system must comprise standardized system components such as:
● Straight trunking units with and without tap-off points
● Feeder units for incoming transformer, distribution board and cable connection units
● Junction units with elbow, offset elbow, knee, offset knee, Z units and T units
● Tap-off units
● Accessories
All straight trunking units must be available in lengths up to 3 m ex-works. It is not permitted
to set up flexible junction units and junction units using cable connections. Expansion units
and fixed points must be planned as per requirements.
Tap-off units are connected to the tap-off openings on the trunking units as required. It must
be possible to select the number and position of tap-off points.
If required, it must be possible to fit the busbar trunking system with an asbestos-free
fireproof barrier for wall or ceiling mounting, that is tested to EN 1366-3 and that complies
optionally with fire resistance class EI90 or EI120 in accordance with EN 13501.

5.3 Conformity and test certificates
SIVACON 8PS - Planning with SIVACON 8PS
Planning Manual, 11/2016, A5E01541101-04 161
If required, it must be possible to offer the busbar trunking system with functional endurance
class E15, E30, E60 or E90 acc. to DIN 4102-12. Fire protection for functional endurance
must be installed on-site by the installation engineer. The certificate for functional endurance
must be included with the offer.
The enclosure consists of aluminium painted light grey (RAL 7035).
The individual system modules are connected by hanging a hook from a bolt and tightening
a state-of-the-art maintenance-free bolt clamp. The torque of 50 Nm required for terminal
connection must be indicated by shearing the outer part of the shear nut. If the shear nut is
not tightened with 50 Nm, the cover of the terminal connection must not be put in place.

Selection example
A rated current of 2500 A is calculated for a project. Aluminium shall be used as the
conductor material, and Mylar as the insulation material. A 5-pole system has to be used.
The cross section of the neutral conductor needs to be equal to the cross section of the
phase conductor.
The following type is obtained:
LI-AM25005B
Sizes
Sizes are dependent upon rated current and conductor material. In total, there are ten sizes.
Six sizes are set up as single systems and three as double systems for the version with
aluminium and copper.
Single systems comprise one enclosure with between 3 and 6 aluminium or copper bars.
Double systems have between 6 and 12 bars in two enclosures.
The precise number of bars is determined by the required conductor configuration.

Structure of the busbars
The bars in the LI busbar system are usually tinned and enclosed in a sleeve made of highly
resistant insulating material. The LI-A system features aluminium conductors and the LI-C
system copper conductors. In addition to tinning, aluminium bars are also coated with a layer
of nickel.

Mounting positions and rated current
The sandwich design means that the current carrying capacity of the LI busbar system is not
affected by the mounting position. This guarantees high flexibility for positioning the busbar
runs. Current derating is not normally required for busbars in edgewise and flat positions on
horizontal busbar runs or on rising main busbars (vertical busbar runs). Deviations for the
horizontal flat mounting position are listed in the technical data of the respective system size.

Busbar connection unit for non-Siemens distribution boards
If you wish to connect the busbar trunking system to a non-Siemens distribution board, you
can establish this connection using a busbar connection unit LI. .... - FA for non-Siemens
distribution boards. The connection unit is built into the distribution board and serves as an
interface to the copper connections of the distribution system.
Versions
Depending on system type, a total of eight different conductor configurations are available
for selection. The rated currents up to a maximum of 6300 A correspond to the specifications
in the chapter "Technical specifications (Page 197)". In accordance with DIN EN 61439-1
and DIN EN 61439-6, the temperature limit in distribution systems in the event of heat rise
must not be exceeded by the current heat. The temperature limit of busbars sheathed with
insulating materials is 135 °C. You can find the required conductor cross-sections for the
copper connections in the chapter "Technical specifications (Page 197)".
Installation of the busbar connection unit
The busbar connection unit in the distribution board must be copper-plated by the board
manufacturer or in compliance with that manufacturer's specifications. The board
manufacturer must ensure that the required short-circuit strength is achieved and the
permissible temperature limit of the busbar connection unit for non-Siemens distribution
boards is not exceeded.

Note
Hot plugging
In accordance with DIN EN 50110
-1 (VDE 0105-1), national regulations must be observed.
Country
-specific regulations may prohibit plugging when the busbar run is not switched off
and energized with electrical power.
Cable entry
You can insert the cables optionally from the side or the front. Integrated flange with cable
grommets facilitates multi-core cable entry. Aluminium plates are used for single-core cable
entry; you have to fit these with cable glands locally. Blanking plates are attached at the side
for delivery.
Safety during operation
To open the tap-off units, you must switch the breaker off either by actuation of the handle
or at the motorised operating mechanism of the breaker. Once this is done, the cable
connection area is no longer energized. The part of the contact device in the front of the tap-
off unit is “finger-safe".
Implementing the tap-offs
Tap-offs are required for different amperages depending on the size and type of loads
involved. These are implemented by means of plug-in tap-off units up to 1250 A.

Thanks to its cast epoxy enclosure with high IP68 degree of protection and high short-circuit
rating, the LR system can provide an assurance of reliable power transmission even under
the harshest ambient conditions. It is entirely resistant to environmental factors such as air
humidity and corrosive or salty atmospheres.
The compact system is suitable for flat, edgewise, vertical or horizontal installation as per
requirements in applications from 400 A to 6300 A. Bracket pieces, connectors and T pieces
to create junction units facilitate optimisation in line with structural conditions within the most
compact of dimensions. The LR system is even ideal for use outdoors.
6.2
System components
6.2.1
Preliminary remark for specifications
Basic description busbar trunking systems 400 A to 6300 A
Busbar trunking systems shall be supplied and installed as type-tested and ready-to-use low-
voltage switchgear assemblies.
The following descriptions are part of the costing and contracts process. They must be
considered when specifying individual systems and equipment, even if they are not
subsequently referred to in more detail.
The busbar trunking system has to be suitable for power transmission, e.g. between
transformer and low-voltage main distribution board, and power distribution in the form of a
power supply, as well as for horizontal and vertical installation.
The busbar trunking system must comprise listed system components such as:
● Straight trunking units
● Feeder units for incoming transformer, distribution board and cable connection units
● Junction units with elbow, offset elbow, knee, offset knee, Z units and T units
● Joint units
● Accessories
The busbar trunking system must comprise standardised factory-built system components. It
is not permitted to set up flexible junction units and junction units using cable connections.
Expansion units and fixed points must be planned as per requirements.
Standard components are connected to the tap points on the trunking units as required. It
must be possible to select the number and position of tap-off points. The bolt-on tap-off units
can only be installed and removed when voltage-free.
If required, it must be possible to fit the busbar trunking system with an asbestos-free
fireproof barrier for wall or ceiling mounting which is compliant with the fire resistance class
S60, S90 or S120.
The enclosure is of epoxy resin and is corrosion-free. The cross section of the trunking units
must not exceed the dimensions specified in the technical data.
Planning with LR
6.2 System components
SIVACON 8PS - Planning with SIVACON 8PS
Planning Manual, 11/2016, A5E01541101-04 237
The individual system components must be connected by screwing on a state-of-the-art
bolted joint block.
The connection must be encapsulated in cast resin and closed following installation of the
bolted joint block.
The busbars must be made of copper-coated aluminium or copper. The outer dimensions of
the enclosure/casing must not exceed the values specified in the technical data.
The fire load must not exceed the value specified in the technical data.
Conformity and test certificates
The manufacturer of the busbar system must have in place and be able to prove compliance
with a quality management system in accordance with EN ISO 9001.
Proof of compliance with the following requirements must be provided for the entire system
in the form of certificates or declarations of conformity:
● Type test acc. to IEC / EN 61439-1 and -6
● Resistance to extreme climates acc. to IEC 60068-2-78 (constant) and IEC 60068-2-30
(cyclic)
● Fire protection acc. to DIN 4102--9
Reliable proof of special additional characteristics (e.g. functional endurance) of system
components must be provided.

6.2.2
Type code
The components of the LR system are determined using a type code. The type is specified
and selected on the basis of rated current, conductor material and system type or conductor
configuration.
The resulting type code enables the product to be ordered to be precisely defined.
Figure 6-2 Type codes LRA/LRC
Selection example:
A rated current of 2500 A is calculated for a project. A 5-pole system has to be used.
This results in type
LRC0851-0
.

6.2.3
System sizes and structure
Sizes
The sizes are dependent upon the rated current rating. In total, there are nine sizes. Six
sizes are set up as single systems and three as double systems.
Single systems comprise one enclosure with 4 to 5 aluminium busbars for the LRA system
and 4 to 5 copper bars for the LRC system. Double systems have between 8 and 10 bars in
two enclosures.
The precise number of bars is determined by the required conductor configuration.
Structure of the busbars
The busbars of the LRA system are surface-treated (copper-coated), and the busbars of the
LRC system are not.

Mounting positions and rated current
The cast resin construction means that the current carrying capacity of the the LR busbar
system is independent of the mounting position. This guarantees high flexibility for
positioning the busbar runs. Current derating is not required for busbars in edgewise and flat
positions on horizontal busbar runs or on rising main busbars (vertical busbar runs).

Busbar connection unit for non-Siemens distribution boards
If you wish to connect the busbar trunking system to a non-Siemens distribution board, you
can establish this connection using a busbar connection unit LR....-T. for non-Siemens
distribution boards. The connection unit is built into the distribution board and serves as an
interface to the copper connections of the distribution system.
Versions
Aluminium or copper conductors are used for connection units for non-Siemens distribution
boards. The rated currents up to a maximum of 6300 A correspond to the specifications in
chapter "Technical specifications (Page 252)". The required conductor cross sections for
copper connections are also listed in the chapter "Technical specifications (Page 252)".
Installation of the busbar connection unit
The busbar connection unit in the distribution board must be copper-plated by the board
manufacturer or in compliance with that manufacturer's specifications. The board
manufacturer must ensure that the required short-circuit strength is achieved and the
permissible temperature limit of the busbar connection unit for non-Siemens distribution
boards is not exceeded.

Connection unit for transformers and distribution boards
The wide variety of transformer types reflects the variety of rated currents and the different
phase sequences and clearances.
This type variety requires high flexibility as regards transformer connection in busbar
trunking systems.
The universal connection unit can also be used to connect distribution boards.
For LR busbar trunking systems up to 6300 A, transformer connection units are available
with busbar connection on the side (LR....-TC, -TD or -TE) and on the top (LR....-TJ, -TG, -
TM, -TK or -TX).

Tap-offs for power distribution
The LR system has been designed purely for power transmission. However, power tap-offs
for loads can be created by adding straight trunking units with junction points and
corresponding junction boxes to the LR run.
Note
Junction boxes are available on request.
x =
X = 0.50 … 3.00 m
Figure 6-9 Straight trunking unit with junction box
The tap-off unit permits rated currents of up to 630 A. An equipment compartment is built
onto the tap-off unit. Project-specific switchgear (e.g. circuit breakers) is installed in the
compartment and connected - both electrically and mechanically - to the tap-off unit.
Tap-off units are not designed for connection whilst the LRC system is live.
All other characteristics and technical data can only be provided on request for specific
projects.

Joint block
The joint block is used for the trunking units' electrical and mechanical connections. LR
trunking units are usually supplied without joint units (junction blocks or monoblocks, as they
are also known). Accordingly, you need to make provision to plan and order joint blocks
separately as appropriate for the number of trunking unit connections.
Figure 6-10 Joint unit
Accessories for busbar connections with joint blocks
Once the electrical link with the joint block has been established, it needs to be cast with
epoxy resin. For this purpose, moulding casts, cast resin mix, separators and various tools
are provided as accessories.

Determining the voltage drop
Formula for voltage drop
With long trunking runs it may be necessary to calculate the voltage drop:
Δ
U
= voltage drop (V)
I
B
= rated current (A)
l
= total length of system (m)
k
= load distribution factor
R1
= ohmic resistance (mΩ/m) with busbar final heating
X1
= inductive resistance (mΩ/m) with busbar final heating
cos φ
= power factor
The load distribution factor k for calculating the voltage drop at the end of the busbar
trunking system is defined as follows:
● k = 1, if the load is concentrated at the end of the busbar trunking system (power
transmission).
● k = (n +1)/(2 x n), if the load is distributed across n taps.
To calculate the voltage drop in the distance d between the start of a tap and the start of the
busbar system, proceed as follows:
● k = (2 x n + 1 – n x d/L)/(2 x n)
Voltage drop diagrams
The following diagrams illustrate the voltage drop on the BD2, LD, LI and LR systems
● taking into account the final heating resistances (in accordance with 61439-6)
● with a load distribution factor
– k = 1 for LD and LR
– k = 0.5 for BD2 and LI
● at rated current load. (In the case of a different current diversity factor, the value of the
curve must be multiplied by the appropriate distribution factor).

7.1.2
Overload protection and short-circuit protection
Busbar trunking systems need to be protected against short circuits and overloads. Fuses
and circuit breakers are available for use as protective devices. When selecting protective
devices, the level of the expected short-circuit currents, selectivity requirements or operating
and signalling functions are also factors for consideration.
When deciding to provide short-circuit protection using fuses and circuit breakers, you must
not exceed the specified short-circuit ratings of the busbar trunking systems. Whether a
current limiting protective device is required and what short-circuit breaking capacity the
protective device must have depend on the level of expected short-circuit current.
The table below offers an overview of the circuit-breakers which are able to provide short-
circuit and overload protection (400 V and 50 Hz) for the corresponding busbar system.

The tripping characteristic of the protective device must be selected as appropriate for the short-circuit rating of the
busbar systems, the type of system, the type and number of loads, as well as in line with country-specific regulations
and type series. This table contains only a brief overview of BD2 on the use of circuit breakers for protection against
short-circuit and overload, and it is intended only as a recommendation. We always recommend that you carry out a
calculation using the SIMARIS design network tool to determine the appropriate protection. Please contact our TIP spe-
cialists for this purpose.

7.1.3
Loop impedance
As the level of loop impedance is decisive as regards the magnitude of the 1-pole short-
circuit current, DIN VDE 0100-600 prescribes that loop impedance must be determined
between:
● Phasel conductor and protective conductor or
● Phase conductor and PEN conductor
The value can be determined by means of:
● Measurements taken using measuring instruments
● Calculation
● Simulating the network in the network model
The loop impedances of a busbar trunking system represent part of the total loop
impedance. You can find the impedance values for calculating the loop impedances of a
busbar trunking system in the following chapters:
● For the BD2 busbar trunking system in the chapter titled "Technical specifications
(Page 62)"
● For the LD busbar trunking system in the chapter "Technical specifications (Page 128)"
● For the LI busbar trunking system in the chapter "Technical specifications (Page 197)"
● For the LR busbar trunking system in the chapter "Technical specifications (Page 252)"
Calculating the loop impedance of all contributory equipment in a system (incoming power
supply, transformers, distribution boards, cable runs, etc.) takes a great deal of time and
effort. In this regard, planning time and effort can be reduced significantly by using a
dimensioning program such as SIMARIS design which stores the necessary data for most
common electrical equipment in a database.
7.1.4
Degrees of protection for busbar trunking systems
Use in areas at risk of fire
In areas at risk of fire, in accordance with European standard HD 384.4.482 S1, increased
requirements are placed on the degree of protection to be afforded for electrical equipment.
In the event of a fire risk due to the nature of the materials being processed or stored, the
minimum degree of protection must be equivalent to IP5X if there is a potential for dust
accumulation. If dust is not to be expected, national regulations shall apply accordingly.
The risk prevention arm of the association of German insurers sets out the following
requirements:
● In the event of a fire risk due to dust and/or fibres: IP5X degree of protection
● In the event of a fire risk due to other readily flammable solid foreign bodies with a
diameter of 1 mm or more: IP4X degree of protection
SIVACON 8PS busbar trunking systems meet these requirements. They are therefore
suitable for such applications.

Protection against direct contact according to DIN EN 50274
These regulations must be complied with when dimensioning and laying out electrical
equipment in electrical systems with rated voltages up to 1000 V AC or 1500 V DC with
regard to protection against direct contact, insofar as actuators (pushbuttons, rockers, etc.)
are located in the vicinity of touch-hazardous parts.
“Finger-safe" touch protection only applies to the actuator in the actuating direction.
Measured from the central point, a clearance with a radius of r = 30 mm must be maintained
between the actuator and touch-hazardous parts. Degree of protection IP20 is more than
“finger-safe" touch protection. It includes touch protection of electrical equipment from all
directions. For devices with “finger-safe" touch protection and IP00 degree of protection,
direct contact protection can be provided on request in the form of covers.

The IT system has no direct link between active conductors and earthed parts; the exposed
parts of the electrical installation are earthed.
Today's IT systems feature protective measures in the form of a protective-conductor
system.

Applicable regulations
"Fire prevention devices and fire prevention measures" for electrical installations are
required in particular in buildings of special types and used for special purposes. Examples
of these types of building include hospitals and public buildings. In this regard,
DIN VDE 0100-560 relating to buildings and structures for public use and DIN VDE 0100-710
(previously DIN VDE 0107) relating to medical locations, and/or legal requirements specify
that the electrical installations in such buildings must maintain functional endurance for
specific lengths of time even in the event of a fire. This requirement affects the following
equipment in particular:
● Fire alarm systems
● Systems for alerting and providing instructions to visitors and employees
● Emergency lighting
● Passenger lifts with evacuation circuits that assure functional performance for at least
30 minutes in the incoming cable area under full fire conditions
● Water pressure boosting systems for the supply of extinguishing water
● Ventilating systems of safety stairwells, fire department lifts and machine rooms where
functioning must be guaranteed for at least 90 minutes.
To be able to offer the required functional endurance for busbar trunking systems, we have,
for example (in some cases working together with Promat), had the BD2, LD, LI and LR
busbar trunking systems tested successfully at the Materials Testing Institute in
Braunschweig and Leipzig in Germany.
During fire testing the busbar trunking systems concerned (housed in Promatect plate
casings of varying thicknesses) were subjected in this respect to an external fire load in
compliance with the standard temperature curve (STC) to evaluate functional endurance to
DIN 4102-12.

Versions
Special components for the functional endurance channel as well as the carrier construction
for the channel and BD2, LD, LR and LI busbar trunking systems are vital to compliance with
functional endurance requirements. The design of the channel (barriers on 4 and 3 sides)
and the carrier construction (fixing with threaded rods or wall-mounted cable brackets) can
vary depending on ambient conditions. Observance of/compliance with the specifications of
test certification issued by planning authorities is mandatory:
● Observance of the maximum permissible clearances between the mounting points, and a
maximum permissible tensile stress of 6 N / mm²
● Use only fixing accessories approved by planning authorities and barrier material incl.
barrier accessories. This material must be provided by the customer and is not included
in the scope of supply of the busbar trunking system.
The following versions can be considered:

Fireproof barrier
7.4.1
Busbar trunking system with fireproof barrier
German building regulations (or other national regulations) require that buildings are
constructed in such a way as to "prevent the development and spread of fire and fumes and
make possible the rescue of persons and animals as well as fire fighting". Accordingly,
neither fire nor fumes are permitted to spread from one floor or fire area to another.
The BD01, BD2, LD, LI and LR busbar trunking systems can be equipped with fireproof
barriers. Fireproof barriers are generally subject to the device standard IEC / EN 61439-6
and national regulations, and these can differ from each other. For this reason, we
recommend that you contact your SIEMENS representative in the planning phase.
The systems meet the requirements for proving fire resistance duration as per the fire
resistance class specifications in ISO 834-1 in accordance with IEC / EN 61439-6.
①
Permissible surface temperature on components (on the opposite side to the fire) max. 180K
above the starting temperature
②
Area on fire: Fire in accordance with standard temperature curve DIN 4102, Sheet 2 or
DIN EN 1363-1
③
Permissible temperature increase of escaping air max. 140°C
④
Flammable gases must not be allowed to escape. No fumes likely to impair rescue attempts
must be allowed to escape

7.4.2
Versions
Unlike cable trunking, the busbar trunking systems are supplied ex-works with a fireproof
barrier. The fireproofing consists of an inner and outer barrier or an outer barrier only
depending on the busbar trunking system.
The fireproof barriers are compliant with fire resistance classes S60, S90 and S120 in
accordance with DIN 4102-9 dependent upon version and type (EI60, EI90 and EI120
available soon).
The fireproof barrier can be installed in the busbar trunking system at the factory (BD2, LD),
added on site (BD01, LI, LR), or omitted completely (LR). Please note the section "Special
conditions for the German market" in this regard.
The type of installation is determined by the structure of the busbar trunking system and the
required fire resistance class, as you can see from the overview below (the figures ignore the
minimum clearances between the fireproof barrier and the wall, and the fireproof mortar):

Special conditions for the German market:
The versions for fire barriers described here were created on the basis of tests passed in
accordance with DIN 4102 Part 9 or EN 1366-3. In Germany, fireproof barriers must possess
general planning authority approval or a European technical approval. These are issued by
the German Institute for Civil Engineering in Berlin. All divergences from the approval must
be clarified with the product manager for the purpose of applying to the respective regional
building authority for agreement in individual cases if necessary.
Fire safety tests have been carried out successfully for the installation of fireproof barriers in
stud walls for the BD01, BD2, LD and LI systems. Please contact the relevant product
manager for more detailed information about designs and approvals.

Planning Manual, 11/2016, A5E01541101-04 289
Note
Following installation, you must fill the space between the busbar trunking system or the fire
protection block and the wall or ceiling cut
-out with non-combustible material such as
concrete or mortar to the thickness of the wall or ceiling. The concrete or mortar must comply
with the applicable regulations to maintain the fire resistance class of the wall or ceiling, (e.g.
EN
206-1 and EN 998-2).
Note
Minimum clearance
For the installation of SIVACON 8PS busbar systems with fire protection, a minimum
clearance of 5 cm must be maintained between the system or system fire protection and the
structure in the cut
-out. This ensures that there is sufficient space to mount the
run, the fixing
brackets and for filling with mortar.

SIVACON 8PS - Planning with SIVACON 8PS
Planning Manual, 11/2016, A5E01541101-04 301
7.6
Magnetic fields
General information
Due to their physical characteristics, busbars designed for power distribution and
transmission generate pulsating electromagnetic fields in their vicinity with a fundamental
frequency of 50 Hz. These magnetic fields can impair the ability of sensitive equipment such
as computers or metering instruments to function in full working order.
Limits
EMC directives and the associated standards do not set out requirements or
recommendations for the planning of busbar trunking systems. DIN VDE 0100-710 can be
consulted in relation to busbar trunking systems used in hospitals.
DIN VDE 0100-710 defines limits for line frequency magnetic fields in hospitals. For
example, at 50 Hz, the magnetic induction around a patient's bed must not exceed the
following values:
B= 2 x 10-7 tesla for EEG
B = 4 x 10-7 tesla for ECG
The limit for inductive interference between multi-core cables and lines in a high voltage
installation (conductor cross section > 185 mm2) and the patient beds to be protected is
safely undershot if the minimum clearance of 9 m recommended in DIN VDE 0100-710 is
complied with.
When using busbars, this clearance can generally be reduced, since the busbar systems are
designed to effectively reduce the magnetic interference fields in the local vicinity.
Magnetic field measurements
However, in order to facilitate evaluation of the busbars to be used in the planning phase,
extensive magnetic field measurements have been taken in accordance with EN 61439-6.
The magnetic field emissions of the busbar systems were measured on a straight trunking
run that was 9.0 m long. With the busbars under a balanced rated current load, the magnetic
fields were measures in eight directions at intervals of 0.1 m and up to a clearance of 1 m.

Sprinkler test
General information
Sprinkler systems are used for fire prevention and protection in buildings and industrial
facilities. Sprinkler systems are automatic fire extinguishing systems. They are designed to
detect the outbreak of fire at an early stage and extinguish it as quickly as possible. Once
activated for the purpose of extinguishing fire, such systems usually run for at least 30
minutes.
The BD2, LD and LI busbar trunking systems have been subjected to a sprinkler test. In the
absence of a binding standard, the tests were carried out based on a test structure reflecting
practical application (see diagram).

Test results
BD2 and LI
All mounting positions of the BD2 and LI busbar trunking systems were tested for water
resistance in degree of protection IP54 on the basis of the national risk prevention guidelines
for sprinkler systems issued in Germany. Insulation resistance measurements were taken
before and after the 90-minute sprinkling period and a high-voltage test was carried out in
accordance with IEC / EN 61439-6 . The equipment passed the test, proving that the busbar
system can be put back into operation immediately and without delay once the sprinkler
system has run its course.
LD
The LD busbar system with degree of protection IP34 and the associated tap-off units with
degree of protection IP54 were sprinkled with both horizontal and vertical trunking runs with
a 3/4" umbrella sprinkler and a 1/2" flat spray sprinkler at a water pressure of 6 bar. In order
to be able to assess electrical performance during testing, insulation resistance
measurements were taken during the course of the test. No operational failures occurred.
Even when subject to extreme water loads such as those associated with sprinkler systems,
the LD busbar system is able to remain in full working order. This operational reliability is
made possible on the one hand by the generous creepages and clearances and on the other
by the fact that water can drain away unhindered.

Conditional rated short-circuit current (Icc) DIN EN 61439-1; 5.3.5, IEC / EN 61439-1
The conditional rated short-circuit current corresponds to the prospective short-circuit current
that a circuit in a switchgear and controlgear assembly, protected by a short-circuit protective
device, can carry without damage (for a certain time). The conditional rated short-circuit
current is therefore specified for tap-off units and/or infeeds with circuit breakers, for
example.
Rated control voltage (Uc) DIN EN 60947-1; 4.5.1
This is the voltage that is applied to the normally-open actuation contact in a control circuit. It
may deviate from the rated control supply voltage due to transformers or resistors in the
switching circuit.
Rated current (In) (of a circuit breaker) DIN EN 60947-2; 4.3.2.3
Current which, for circuit breakers, corresponds to the rated continuous current and the
conventional thermal current.
➜ Rated uninterrupted current
Rated current (In) (of a circuit of a circuit breaker assembly) DIN EN 61439-1; 5.3.2
The rated current of a circuit of a switchgear and controlgear assembly is specified by the
manufacturer and depends on the rated values of the individual items of electrical equipment
in the circuit within the switchgear and controlgear assembly, their arrangement, and type of
use. The circuit must be able to carry the rated current without the overtemperatures on the
individual components exceeding the limit values defined in 9.2 (Table 6) when tested
according to 10.10.2.
Rated frequency DIN EN 60947-1; 4.3.3
Frequency for which switching devices are dimensioned and to which the other characteristic
data refer.

→ Rated operating voltage
Rated short-circuit current, conditional (Icc) DIN EN 60947-1; 2.5.29
➜ Conditional rated short-circuit current (
I
cc)
Rated short-circuit making capacity (Icm) DIN EN 60947-1; 4.3.6.2
The highest current that a switching device can make at a specific rated operating voltage
and frequency without damage. Deviating from the other characteristic data, the value is
stated as the peak value.
→ Rated operating voltage
Rated short-time withstand current (Icw) DIN EN 61439-1; 5.3.4, IEC / EN 61439-1
As the effective short-circuit current value, the rated short-time withstand current
characterises the thermal strength of switchgear and controlgear assembly circuits during a
short-time load. The rated short-time withstand current is normally determined for a duration
of 1 s; divergent time values must be specified. The rated short-time withstand current is
specified for the trunking and/or main busbars of a switchgear and controlgear assembly.
Rated ultimate short-circuit breaking capacity (Icu) DIN EN 60947-2; 4.3.5.2.1
The maximum short-circuit current that a circuit breaker is capable of breaking (test O - CO,
previously P-1). After short-circuit breaking, the circuit breaker is capable of tripping under an
overload, with increased tolerances.
Rated uninterrupted current (Iu) DIN EN 60947-1; 4.3.2.4
The current that a switching device can carry during continuous operation (for weeks,
months or years).
Specification of rated values
The manufacturers of low-voltage switchgear and controlgear assemblies specify rated
values in compliance with DIN EN 61439-1. These rated values apply to specified operating
conditions and characterise the suitability of a switchgear assembly. Use these ratings for
coordination of the equipment and configuration of the switchgear assemblies.
