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.

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

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.
