IAL/IUL/IEL/LEL magnetic circuit
breakers 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 require-
ments, 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 and the LEL
models are UL listed under the
conditions of UL 489. Both are
CSA certified.
Airpax type IAL/IUL/IEL/LEL
circuit breakers 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.

IAL/IUL/IEL/LEL MULTI-POLE CIRCUIT BREAKERS
IAL/IUL/IEL/LEL Multi-Pole Circuit Breakers
154
Multi-pole breakers 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.
Tw o Pole Breakers
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.

IAL/IUL/IEL CONFIGURATIONS
Series Trip
The most popular configuration for magnetic protectors
is the series trip where the sensing coil 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 / SNAP-IN MOUNTING OPTIONS
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 circuit
and 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 specifica-
tion 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 ship-
ment, 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.

ROCB Remote Operated Circuit Breaker
162
The Airpax Remote Operated Circuit (ROCB) provides the convenience
of remote power disconnect and reset capability with the safety and
accuracy of a magnetic current sensing device. It allows the operation
of the circuit breaker from various locations in the system, facility or site,
while not sacrificing the ability to manually operate the breaker if required.
Service, diagnostics, load shedding and power distribution control
functions can now be performed in areas that were previously unattended,
inaccessible or unsafe.
Based on our popular IEL/LEL circuit breaker series, the ROCB shares
the same dimensional characteristics (maximum three poles plus the remote
operator) for easy adaptation into existing panel designs, yet its compact
size allows efficient use of space for new design applications. In addition,
the ROCB has been designed to meet the requirements of domestic and
international agency standards for motor operated circuit protection,
ensuring worldwide component acceptance.

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.
IEL/IUL/IAL/LEL DELAY CURVES
Inrush Pulse Tolerance
The table on page 163 provides a comparison of inrush pulse
tolerance with and without the inertia delay feature for each of
the 50/60Hz delays. 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 below provides a guide to determine if the inertia
delay feature is required. Consult factory for further assistance.

IAL/IUL/IEL DECISION TABLES
How to Order
The ordering code for IAL/IUL/IEL/LEL
circuit breakers 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.
