INTRODUCTION
IAL/IUL/IEL/LEL magnetic circuit protectors provide low-cost
power switching, reliable circuit protection and accurate
circuit control for equipment in the international marketplace.
IAL models are for those applications where the unit’s inherent
attributes are desired, but compliance with the various
standards is not required.
IUL models have been tested and approved in accordance with
UL 1077 requirements for UL recognition.
IEL/LEL models are VDE approved to VDE 0660, part 101. They
meet IEC spacing requirements, mandatory for equipment
which must comply with IEC specifications 601 and 950, and
VDE specifications 0804 and 0805. In addition, the IEL models
are UL recognized to UL 1077 as supplementary protectors and
the LEL models are UL listed under the conditions of UL 489. Both
are CSA certified and CCC Approved. The IEL is CSA certified as
a supplementary protector per CSA C22.2–No. 235.
The CEL model has achieved two new enhancements, including
a single pole, 125 amp rating with TÜV approval, and a parallel
4-pole version with 400 amp rating.
Airpax™ IAL/CEL/LEL circuit protectors are available in a wide
variety of configurations, including series, series with auxiliary
switch, shunt and relay with choice of delays and ratings in DC
and/or 50/60Hz or 400Hz versions. Single or multi-pole versions
are available with a variety of pole arrangements to meet your
specifications. Please see the appropriate product specification
table for ratings and limitations.

Multi-pole units are combined in an assembly with the trip
mechanisms internally coupled. A fault in any protected circuit
opens all poles simultaneously. Applications include use in
polyphase circuits, single-phase three-wire systems, or in two
or more related but electrically isolated circuits. A mix of
delays, ratings and configurations are offered. The auxiliary
switch is offered with either gold or silver contacts and is
available when a series construction pole is specified.
Two Pole Units
An assembly consisting of two single pole units, having their trip
mechanisms internally coupled, is available with either a single
toggle handle or with a handle per pole. Please see decision
one of the part number decision tables. Individual poles may
vary in ratings, delays and internal configurations. If the poles
are of series construction, an auxiliary switch may be included
in either or both poles, allowing you to mix SELV and hazardous
voltages.

and contacts are in series with the load being
protected. The handle position conveniently
indicates circuit status. In addition to providing
conventional overcurrent protection, it’s
simultaneously used as an on-off switch.
Shunt Trip
The shunt trip is designed for controlling two
separate loads with one assembly. The control is
established by providing overload protection for the
critical load. When the current through this load
becomes excessive and reaches the trip point, the
protector will open and remove power from both
loads simultaneously. The total current rating of both
loads must not exceed the maximum contact rating.
Dual Coil
By combining two electrically independent coils on
a common magnetic circuit, it is possible to provide
contact opening when either an over-current or trip
voltage is applied to the respective coils. One coil
will be a current trip coil with standard
specifications. The second, or dual coil, can be used
to provide a control function permitting contact
opening from a remote interlock or other transducer
functions. Standard coils are 6, 12, 24, 48, 120 and
240 volts. Tripping is instantaneous and must be
removed (usually self-interrupting) after trip.
Auxiliary Switch (Applies to Series Trip Only)
This is furnished as an integral part of a series pole
in single or multi-pole assemblies. Isolated
electrically from the protector’s circuit, the switch
works in unison with the power contacts and
provides indication at a remote location of the
protector’s on-off status.
Auxiliary switch contacts actuate simultaneously
with the main breaker contacts, and will open
regardless of whether the breaker contacts are
opened manually or electrically. For auxiliary switch
ratings below 6Vac or 5Vdc, an auxiliary switch with
gold contacts, designated as REG is available. Gold
contacts are not recommended for load current
above 100 milliamps.

Relay Trip
This permits the overload sensing coil to be placed in a
circuit which is electrically isolated from the trip contacts.
The coil may be actuated by sensors monitoring pressure,
flow, temperature, speed, etc. Other typical applications
include crowbar, interlock and emergency/rapid shutdown
circuitry. Trip may be accomplished by voltage or current,
which must be removed after trip.
Voltage Trip
Sometimes called “dump circuits” or “panic trip circuits,”
these units make it possible to open main power contacts
with lower power inputs from one or more sources. This
configuration is becoming increasingly more important for
sensitive circuitry and denser packaging in automation
systems. Available in series, shunt or relay configurations.

Mid-Trip Indication
Circuit protection, rapid fault location
and alarm capability are blended
together in the Airpax mid-trip
indication option. This option is
designed for automatic handle
movement to a middle position upon
electrical overload, allowing for easier
detection of the fault circuitand
minimizing downtime due to the
overload condition.
In the optional auxiliary switch
configuration, the switch allows an
alarm or signal to be forwarded when
the breaker trips and the handle
moves to the middle position. The
alarm can be disengaged by the
manual actuation of the handle to the
OFF position. Once the fault has been
corrected, the circuit breaker can be
reset to the ON position. The mid-trip
option is available in one, two or three
pole toggle handle packages and in
either standard panel screw or snap-in
mounting. Please see specification
tables of specific product for available
ratings.
Snap-In Mounting
The snap-in mounting adapter allows for
simplified mounting of most IEL/LEL
toggle handle products. Prior to
shipment, the adapter is attached to the
circuit breaker during our final product
assembly, allowing you to securely snap
the unit into a rectangular panel cut-out.
This eliminates the need for panel
mounting hardware and associated
assembly costs.
Available for units up to three poles,
with or without an option handle
guard.

400Hz, DC, 50/60Hz Delay Curves (typ)
A choice of delays is offered for DC, 50/60Hz, 400Hz, or
combined DC/50/60Hz applications. Delays 49, 59, 69
and 79 provide fast-acting, instantaneous tripping and
are often used to protect sensitive electronic
equipment (not recommended where a known inrush
exists). Delays 41, 51, 61 and 71 have a short delay for
general purpose applications. Delays 42, 52, 62 and 72
are long enough for most transformers and capacitor
loads. Delays 43, 53, 63 and 73 are extra long for
special motor applications.
Inrush Pulse Tolerance
Pulse tolerance is defined as a single pulse of half sine wave
peak current amplitude of 8 milliseconds duration that will
not trip the circuit breaker.
The table on page 171 provides a guide to determine if the
inertia delay feature is required. Consult factory for further
assistance.

IAL/IUL/IEL DECISION TABLES
The ordering code for IAL/IUL/IEL/LEL
circuit protectors may be determined by
following the decision steps in the
appropriate part number decision table
subsequent to this page.
The coding given permits a self-assigning
part number but with certain limitations.
Special applications may require a factory
assigned part number. Typical examples
are units with mixed ratings, combinations
of styles, or constructions not listed in the
third decision table, etc. With these, it is
suggested that order entry be by
description and/or drawings, and a part
number will be established. Additionally, it
is standard policy to establish a factory-
assigned part number whenever a
descriptive drawing exists to provide cross
reference, traceability and manufacturing
control.
When specifying a circuit breaker for AC
motor start or high inrush applications, the
peak amplitude and surge duration should
be specified for factory assistance in rating
selection.
For example the code shown is the code
for a single pole breaker with a series
construction and auxiliary switch,
designed for operation in a 50/60Hz
circuit. It has a short time delay, rating of
20 amperes and a marked black handle,
and is VDE approved.
To determine the ordering number for your
particular IAL/IUL/IEL unit, simply follow
the steps shown. You may use this number
to place an order or as a reference for
further questions you may have.
Notes:
IEL, IELH and IELX circuit protectors are designed
to meet 8mm creepage clearance requirements for
installation Category 111, Pollution Degree 3, Case A as
measured in IEC 664. Intended for use in equipment to
comply with IEC 950, 601 and VDE 0804 & 0805.
