PRODUCT DESCRIPTION
Control power transformers from Schneider Electric set the industry standard for design innovation and
performance. They are designed with low impedance windings for excellent voltage regulation, and
can accomodate the high inrush current associated with contactors, starters, solenoids, and relays.
A variety of designs are available to meet the diverse needs of panel builders and machinery OEMs.
The versatility of our control transformer line offers unparalleled options for design engineers. We also
have one of the most extensive offering of custom products with no minimum order requirements.
We have a national network of distributors to ensure prompt delivery, including industry leading
delivery on custom products. In most cases, we can design, manufacture, and ship a custom unit in
two weeks or less.
The Global Product Offering—Type T
Type T is our most popular and complete line of control transformers. It comes with unmatched design
innovations for top performance and is manufactured using the most advanced insulating materials.
The Type T control transformer is the best choice if size and cost are of concern.
The Exceptional Regulation Offering —Type EO
Constructed with traditional materials and manufacturing processes, Type EO transformers are UL and
CSA Component Recognized. Units are designed for 55°C rise. All units are 60HZ rated, with
de-rated VA levels for 50HZ.
Transformers with Fuse Block Protection—Types TF and EOF
We offer both product lines with factory installed overcurrent protection fuse blocks.
Type TF and EOF transformers consist of two primary fuse blocks and one secondary fuse block, a
configuration that meets the majority of overcurrent needs by panel builders and machinery OEMs.
Since the fuse blocks are pre-wired and mounted on top of the transformer, the Type TF and EOF
transformers have the same footprint as the Type T and Type EO units, respectively. This design frees
up space normally used for separate fuse blocks
We also have an extensive fuse block offering for custom applications. See the overcurrent section of
this catalog for full details.
Leaded Control Transformer Line
Schneider Electric offers transformers with internally pre-wired 24-inch primary and secondary leads,
instead of terminal boards, to make installation easier and faster for many applications. These are only
available for single voltage primary and single voltage secondary applications.
MultiTap
Schneider Electric offers Type T and Type EO transformers in the MultiTap version. The MultiTap
control transformer was designed to respond to the increased need for voltage and stock flexibility. It
combines multiple primary voltages with one or more secondary voltages, all in a single transfomer.
The most flexible MultiTap voltage is the Universal, available on the Type T product line only. It allows
for standard primary voltages of 208 to 600V and 110, 115, or 120V secondary voltages.

TYPE T TRANSFORMERS
The Type T units are designed for the global market and are the best choice
when size and cost are of concern. This is our most popular and complete
offering of industrial control transformers. The following features are
included:
•50/60 Hz rated
•Customer installed accessories (Finger-Safe covers, fuse blocks, fuse
clips)
•Type T transformers are designed with various temperature classes:
— 25–150 VA with a 55° C temperature rise, 105° C insulation
— 200–350 VA with a 80° C temperature rise, 130° C insulation
— 500–5000 VA with a 115° C temperature rise, 180° C insulation
Schneider Electric manufactures a wide variety of voltage combinations for
control transformers. The voltage combinations are expressed as “Voltage
Codes”, and are embedded within the catalog number of the transformer.
Standard codes are listed. If the voltage combination you need is not listed,
please call your Schneider Electric distributor for assistance.
CE Marking
Industrial control transformers (ICTs) entering the European Union (EU)
after January 1, 1997 are required by EU standards to have CE marking or
Declaration of Conformity to CE. EU documentation requires compliance
with specification EN 61 558 of the Low Voltage Directive. Type T ICTs from
Schneider Electric comply with this specification and are third party tested to
TÜV standards, which adhere to, and are accepted by, EU standards. A
Declaration of Conformity for all Type T units is available upon request.
Because of different overload criteria in the CE specification,
Schneider Elecric dual rates these transformers for UL VA, cUL VA, CSA
VA, NOM VA and CE VA ratings (see “Type T VA Ratings” table). Because
they are widely used with control circuit panels, ICTs are also required to
comply with EN 60 204 and EN 61 558 in these applications. The Type T
transformer line complies with EN 60 204 when Fingersafe® covers are
installed.
For more information regarding CE marking, please contact your local
Schneider Electric field sales office.

Selection Guide
1. Determine inrush and sealed VA of each coil in the control circuit and VA
of all other components.
2. Total all sealed VA of all operating coils and other loads VA (determines
minimal VA size required for the circuit).
3. Total the inrush VA of all coils that are starting at the same time and all
loads and coils that are running (using the regulation chart to give
possible units to be used).
4. Take VA size from step 2, go to standard VA size in chart below. Make
sure inrush VA from chart is greater than total VA from step 3. If not, go
to next larger VA size and repeat.
If your supply voltage is stable and fluctuates less than 5%, we recommend
you use the 90% secondary voltage column. If your supply voltage is not
stable and fluctuates more than 10%, we recommend you use the 95%
secondary voltage column. We recommend that you never use the 85%
secondary voltage column since magnetic devices lose life expectancy if
they are continuously started at 85% of rated voltage.
Example:
This example assumes the following:
• Two NEMA size 0 contactors do not start together, but one
could be ON when the other starts.
• One NEMA size 2 contactor can start with either of the
other contactors.
• One pilot light at 2 VA
1. VA and inrush are:
NEMA 0: sealed 27 VA; inrush 245 VA
NEMA 2: sealed 37 VA; inrush 311 VA; pilot light 2 VA
2. Total VA: 27 + 27 + 37 + 2 = 93 VA
3. Total inrush VA: 245 + 311 + 27 + 2 = 582 VA
4. From Regulation Chart for Type T at right below:
100 VA minimum unit; inrush 499 VA will not work at 90%
150 VA (next standard size); inrush 666 VA will work at 95%

simultaneous loading, or 100% loading when 120 V only.
20% rating at 24 V or 100% rating at 120 V gives equal output current from the device.
Tapped Secondary D65: Both outputs fully rated for non-simultaneous loading, and simultaneous rated
for any combination that does not exceed the nameplate VA rating.
Separate Windings Options: All voltage codes offer fully rated non-simultaneous loading, and
simultaneous rated for any combination that does not exceed the nameplate VA rating.
Features of separate windings:
1. Allows two isolated control circuits, 24 V and 120 V, from the same device
2. Wire sizing for circuits for each voltage not highest current for common when simultaneous loading.
(no common)
3. If a common is required, it can be obtained with a jumper kit.

TYPE EO TRANSFORMERS
The Type EO units are designed with exceptional voltage regulation. These
control transformers are constructed using traditional materials and
manufacturing techniques, and are designed for 25 VA to 5000 VA with a
55° C temperature rise. When exceptional regulation and very low
temperature rise are an absolute necessity, choose the Type EO units.
Selection Guide
1. Determine inrush and sealed VA of each coil in the control circuit and VA
of all other components.
2. Total all sealed VA of all operating coils and other loads VA (determines
minimal VA size required for the circuit).
3. Total the inrush VA of all coils that are starting at the same time and all
loads and coils that are running (using the regulation chart to give
possible units to be used).
4. Take VA size from step 2, go to standard VA size in chart below. Make
sure inrush VA from chart is greater than total VA from step 3. If not, go
to next larger VA size and repeat.
If your supply voltage is stable and fluctuates less than 5%, we recommend
you use the 90% secondary voltage column. If your supply voltage is not
stable and fluctuates more than 10%, we recommend you use the 95%
secondary voltage column. We recommend that you never use the 85%
secondary voltage column since magnetic devices lose life expectancy if
they are continuously started at 85% of rated voltage.

Example:
This example assumes the following:
• Two NEMA size 0 contactors do not start together, but one
could be ON when the other starts.
• One NEMA size 2 contactor can start with either of the
other contactors.
• One pilot light at 2 VA
1. VA and inrush are:
NEMA 0: sealed 27 VA; inrush 245 VA
NEMA 2: sealed 37 VA; inrush 311 VA; pilot light 2 VA
2. Total VA: 27 + 27 + 37 + 2 = 93 VA
3. Total inrush VA: 245 + 311 + 27 + 2 = 582 VA
4. From Regulation Chart for Type EO at right below:
100 VA minimum unit; inrush 606 VA will not work at 90%
150 VA (next standard size); inrush 755 VA will work at 95%

Fuse Protection
35
08/2005 © 1999–2005 Schneider Electric All Rights Reserved
FUSE PROTECTION
UL Standards and the National Electric Code require primary protection for Control Transformers, and
many applications require secondary protection. Historically, the fuse options supplied by transformer
manufacturers were designed for Line-to-Line primary (480 V) and Line-to-Neutral secondary (120 V).
Schneider Electric’s new line of fuse options lets customers obtain both factory installed and field
installed fuse blocks. Factory installation saves you time and labor. For both options, the transformer
footprint is identical to a Type T or Type EO transformer of equivalent voltage, because the fuse block
is mounted above the transformer or on the transformer terminal blocks. This frees up space normally
used by separate fuse blocks.
Schneider Electric offers the most complete offering of fuse options to meet all applications for
protection of the transformers and load applications. These are broken down into Line-to-Line and
Line-to-Neutral protection options for both primary and secondary. Due to space limitations of the
transformers, not all options are available for every VA size. Also, all fuse blocks supplied by
Schneider Electric are 30 amp fuse blocks, which limits the VA for each voltage.
All primary fuse blocks supplied by Schneider Electric require rejection style fuses. Rejection style
fuses offer 100,000 AIC protection to comply with UL Standards. (Non-rejection style primary fuse
blocks are available by request only and can be quoted through your Schneider Electric field sales
office.)
Primary voltages requiring Line-to-Line protection: 200/208/220/230/240/380/400/
415/440/460/480/550/575/600
Primary voltages requiring line-to-neutral protection: 100/110/115/120/277/347
Europe: 220/230/240
Secondary voltages requiring line-to-line protection: 208/220/230/240

APPLICATION
In preparation for connecting power to the primary side of dual voltage
single-phase transformers, it's necessary to first wire the two windings in
either series or parallel to match the incoming voltage. An example of this is
common transformers with a primary voltage description of 240 x 480. The
windings are rated for the lower of the two voltages show on either side of
the 'x'. Connecting the windings in series allows for the higher of the two
voltages. Connecting the windings in parallel allows for the lower of the two
voltages.

Technical Data
50/60 Hertz
Transformers that are dual rated for 50/60 Hz are truly global units and no derating is required for
voltages or VA. (Type T are 50/60 Hz; Type EO are 60 Hz with de-rating for 50 Hz).
Base Plates
The development of welded cores has allowed the incorporation of base plates on larger VA
transformers. Base plates are usually welded to the core of the transformer for a solid connection to
the transformer. They allow manufacturers to offer more standardized mounting for specific VA sizes
by allowing multiple core stacks. Available for Type T transformers only.
Touch-Safe Terminals
Being able to offer touch-safe terminals is increasing in importance. Currently all equipment that must
comply with EN 60-204 (Machine and Low Voltage Directives) must have some type of barrier for live
parts. Besides the CE standard listed above, domestic customers are requiring barriers on live parts
with voltages above 460 V. These customers allow Plexiglas™ covers to be installed for these barriers.
Type T transformers can be made Fingersafe® by using snap-on covers that are removable with a
screwdriver or other flat tool. Covers are sold separately.
Formed Terminal Board
Formed terminal boards are used on multiple VA ranges and different voltage combinations. This
allows the manufacturer to punch jumpers for customer interconnections and gives the customer the
same basic layout for all units. The snap-on covers for touch-safe terminations also are available on
units with formed terminal boards. Available for Type T transformers only.
Varnish Vacuum Impregnation
This is a manufacturing process for the core and coil of industrial control transformers. The transformer
is put into a tank of varnish, then the varnish is put into a vacuum, causing the varnish to be forced
throughout the coil and core. After being vacuum impregnated, the units are cured in an oven to seal
the varnish. The varnish is absorbed by any paper insulation system and coats other insulation with
another layer of electrical strength. The process causes the coil to have a very tight connection
because it is completely bonded and mechanically very strong. The cores are also tightly bonded with
the varnish, causing the units to have better heat transfer and less vibration noise.
Schneider Electric uses this process on all control transformers, using a clear varnish with optimum
electrical characteristics.

FREQUENTLY ASKED QUESTIONS
Question Answer
Should you consolidate your control
transformer to a MultiTap or Universal
Control Transformer?
When A Multitap Unit Might Be For You:
1. Transformer will be installed in a device whose source voltage is unknown at time of shipment
2. Space is not critical (MultiTaps are larger than standard units)
3. You sell to markets with multiple source voltages
4. Reduced number of parts will offset premium for MultiTap units
When A MultiTap Unit Might Not Be Beneficial
1. High percentage of your business is 240 x 480 source voltage
2. Space is an issue
3. Source voltage is always known at time of shipment
4. Source voltage changes other components in the control circuit
5. Premium for MultiTap does not get offset by having fewer parts
Can a 9070 type T or TF control transformer
be used in a back (reverse) feed application
as a step-up transformer?
No, they cannot. Industrial control transformers terminals are specifically marked “primary” and ”secondary”. As such,
the National Electrical Code (NEC) and Underwriters Laboratories (UL) prohibit connecting the source to other than
the primary terminals. Also, since industrial control transformers utilize compensated windings to accomodate the high
regulation inherent in such small transformers, the resulting voltage ratio would be lower than desired. In other words,
if a control transformer were reverse fed, the output voltage would be lower than desired.
Does Schneider Electric provide fuses for the
primary and the secondary of a 9070 Type TF
industrial control transformer?
While the 9070 Type TF industrial control transformer comes with a three-pole fuse block (two rejection type Class CC
fuses for the primary, and one non-rejection type midget fuse for the secondary), Schneider Electric does not provide
the fuses. Proper fuse selection is the installer’s responsibility and is dictated by NEC table 450-3(b) and any specific
application parameters that exist with any industrial control transformer installation.
My 9070 Type T or TF industrial control
transformer has four terminals on both the
primary and secondary, but only markings on
the wiring diagram of H1and H2 on the
primary and X1 and X2 on the secondary.
Which terminal do I use?
The nameplate of your Schneider Electric 9070 Type T or TF industrial control transformer clearly marks out that the
outside terminals of each side are used for the customer installed wire connections. Schneider Electric makes a
standard four- or six-terminal block for various transformer designs for commercial cost effectiveness. With only two
terminals being used, it is standard practice for it to always be the outside terminals. Several different transformer
voltage and wiring arrangements are shown in this catalog.
How do the 9070-FB3A, 9070-FB2A, and
9070-FB-1A fuse blocks mount on a 9070
Type T control transformer when factory
installed? When field installed?
When factory installed on a 9070 Type TF control transformer, they mount on the center of the core on factory
installed studs. When field installed by the customer on a 9070 Type T control transformer, they mount over one of the
terminal strips using hardware supplied with the fuse block kit. (There are no studs on the 9070 Type T, only on the
Type TF.)
Does Schneider Electric offer epoxy
encapsulated versions of its 9070 Type T and
TF control power transformers?
Schneider Electric does not offer epoxy encapsulated industrial control transformers. The 9070 Type T and TF
industrial control transformer is the premier offering in the industry and is suitable for virtually any installation
appropriate for a CPT.
What is the sound level for a 9070 Type T
control transformer?
Sound levels for general purpose and control transformers are per NEMA ST-20 sound levels. For Type T control
transformers, this level is 40dB maximum.
Are replacement jumper kits offered for
Schneider Electric’s 9070 Type T and TF
industrial control transformers?
Yes. Replacement jumper kits contain two jumpers per kit and must be ordered in minimum quantities of 50 kits.
Use kit number 30033-027-53 for Accessory Key I (25–200 VA) and Accessory Key II (25–150 VA).
Use kit number 30033-027-54 for Accessory Key I (250–5000 VA), Accessory Key II (200–3000 VA), and Accessory
Key III ( 25–3000 VA).
Do 9070 industrial control transformers
contain any materials, such as PCBs, lead, or
other heavy metals, that would require
special disposal means
Schneider Electric 9070 Type T and TF industrial control transformers do not contain any material that would require
any special disposal means and can be disposed of in the normal manner. Since the majority of the transformer is built
of recyclable material (steel, copper, etc.), Schneider Electric urges the customer to recycle the unit if possible.
What does a “triple rating” mean in terms of
an industrial control transformers voltage
code?
A triple rating on the control transformer`s voltage code basically means that the transformer is designed to
successfully operate at voltages slightly different than the nominal voltage at its full VA capacity. This is done to allow
for different voltage systems that require the same voltage ratios, say 4:1 or 2:1.
Example: The 9070T250D1 is a triple rated voltage code unit that can supply 250VA with the following input voltages
and the corresponding output:
Input: 240 or 480 Output: 120
Input: 230 or 460 Output: 115
Input: 220 or 440 Output: 110
What is the maximum fuse ampere rating that
can be used in a factory or field installed fuse
block or fuse clip for a 9070 Type T control
transformer?
The maximum ampere rating of the fuse blocks and fuse clips offered by Schneider Electric for the 9070 Type T
control transformers is 30 amps. If higher fuse ratings are required, then the customer will have to provide the
supplementary fuse holder provisions.
On a 9070 Type T or TF industrial control
transformer with more than one secondary
voltage available, can more than one
secondary voltage be utilized or only one?
The capabilities of the various 9070 Type T and TF tranformers vary widely. Some units can only have one voltage out
with a given voltage in. Others can have more than one. Contact your Schneider Electric representative for
assistance.
If a satisfactory model is not available, Schneider Electric has the capability of building virtually any industrial control
transformer a customer may need.

Frequently Asked Questions

08/2005 © 1999–2005 Schneider Electric All Rights Reserved
What does the CE VA rating mean in
selecting a 9070 Type T control transformer?
The CE mark is the official marking required by the European Community for all Electric and Electronic equipment that
will be sold, or put into service for the first time, anywhere in the European community. CE VA is the rated capacity of
the control transformer according to the CE standard. By bearing the CE marking, a transformer can be sold into any
of the participating European countries without having to first clear with that country whether it will accept the UL
rating.
An installer had been told by an electrical
engineer to ground a 9070 Type T control
transformer’s frame to the enclosure with a
star washer. If this is so important, why does
Schneider Electric plate the base of the
transformer?
The 9070s base is plated to keep it from rusting. Schneider Electric does not provide grounding provisions on
transformer, as grounding is the responsibility of the installer per NEC requirements.
Does a Schneider Electric 9070 Type T or TF
industrial control transformer have any
continuous overload capacity? What about
momentary overloads due to high inrush
loads, such as may occur with a coil on a
contactor?
Transformers are 100% rated devices. As such, they do not have any continuous overload capacity. They are
specifically designed for momentary currrent draw in excess of their rating for high inrush type loads.
Does a 9070 Type T or TF transformer need
to have its impedance listed on its nameplate
to be used in any particular area in the world?
Industrial control transformers do not have to list their impedance on their nameplate. They can be used anywhere in
the world where their UL, CSA, or CE listing allows, or where they are allowed by the local jurisdiction.
What is the difference between a 9070 Type
T and Type EO control power transformer?
The 9070 Type T is the current design and has both factory and field installed accessories available (such as fuse
blocks, fingersafe covers, fuse pullers, etc.). The Type EO is an established design with better regulation, but does not
have any available accessories.
What is the difference between an old 9070
Type K transformer and a new 9070 Type T?
The CE rated, NOM approved Type T transformer replaces the Type K, which is no longer available. The Type T
matches the Type K in function and form, but not necessarily in fit, i.e., the dimensions may vary.
Does Schneider Electric offer finger safe
covers for use with 9070 Type T and TF
transformer fuse blocks?
The fuse puller accessories (9070FP1) do offer some protection when used and the fuse is in place, however they do
not qualify the block for any additional standards. While the fuse block is CE marked, the fuse puller kit does not
comply with European standards for finger safe as it does not require a tool to remove it. However, this may not be
critical as Schneider Electric does not recommend shipping our fuse block or 9070TF to Europe, as the fuses used
there are different than those used in North America. Thus, the customer should supply their own fuse block suitable
for the European fuses when the transformer is to be used in Europe.
Can a 9070 Type T control power transformer
or a general purpose transformer be used to
provide power for 24V lighting, 120V to 24V
application?
The NEC requires the transformer feeding the low voltage lighting system to be a part of the UL listed lighting system
as assembled by the Original Equipment Manufacturer (OEM). A contractor, distributor, or end user cannot assemble
their own low voltage lighting system and comply with the NEC without going through UL. If the OEM has a particular
transformer listed in their UL file, then that unit may be used.
So if the Schneider Electric 9070 Type T device is part of a lighting system that is UL listed, the answer is yes.
