The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it's simultaneously used as an on-off switch. Dimension B (See Table) SERIES SWITCH ONLY 1.940 [49.28] Dimension A (See Table) Series with Auxiliary 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. .648 [16.46] C NO NC 1.055 [26.80] 1.290 [32.77] BREAKER IN OFF POSITION STUD Terminal TYPES 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.

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. .670 [17.02] 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 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.

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. 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. 1 100 100 10 1 10 1 10 1 .1 .1 .1 .1 .01 .01 .01 .01 0 .001 100 0 150 200100 150 300200 125 125 .001 400300 500400 600500 700600 800700 900800 1000 900 1000 .001 100 0150 200100 150 300200 400300 500400 600500 800700 900800 700600 125 125 PERCENT PERCENT OF RATEDOF CURRENT RATED CURRENT 0 100 100 TIME IN SECONDS 10 1 1000 1000 100 100 10 1 10 1 10 .1 .1 .1 .01 .01 .01 .01 0 .001 100 0150 200100 150 300200 400300 500400 600500 700600 800700 900800 125 125 PERCENT PERCENT OF RATEDOF CURRENT RATED CURRENT .001 1000 900 1000 IAL/IUL/IEL/LEL Series - Delay Curves 0 1000900 1000 1000900 1000 DELAY 69 DELAY 69 1 .1 .001 141 DELAY 63 DELAY 63 10000 TIME IN SECONDS 1000 10000 TIME IN SECONDS 1000 MAY TRIP 10000 TIME IN SECONDS 10000 MAY TRIP PERCENT PERCENT OF RATEDOF CURRENT RATED CURRENT MAY TRIP .001 DELAY 62 DELAY 62 MAY TRIP 1000 MAY TRIP TIME IN SECONDS 10 1000 DELAY 61 DELAY 61 MAY TRIP 100 10000 TIME IN SECONDS 100 10000 TIME IN SECONDS 1000 MAY TRIP 1000 MAY TRIP 10000 TIME IN SECONDS 10000 The table on page 171 provides a guide to determine if the inertia delay feature is required.

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 factoryassigned part number whenever a descriptive drawing exists to provide cross reference, traceability and manufacturing control. 1 First Decision Select Type and Terminal Type Description IAL **IUL ***IEL One handle per unit IALH **IULH ***IELH One handle per pole IALN ***IULN One handle per unit panel seal IALX **IULX ***IELX One handle per unit, rocker, bracket mounting IALZX **IULZX ***IELZX One handle per unit, rocker, integral mounting 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.
