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, its 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 protectors circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protectors 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. switch only series 1.940 [49.28] .281 [7.13] dimension b (see table) dimension a (see table) 1.290 [32.77] .648 [16.46] 1.055 [26.80] nc no c breaker in off position 1.26 [32.00] .278 [7.05] 1.940 [49.28] 2.640 max.

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. c no nc c no nc breaker in on or manually turned off position breaker in mid-trip position (electrically tripped) on position off position mid-trip position (see table) [74.63 .18] 2.938 .007 dim.a?

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. second decision single pole two pole three pole four pole* 1 11 111 1111 2 poles *not available in toggle seal handle type. consult factory for 5 and 6 pole iel part number. internal conguration third decision 3 * only one auxiliary switch is normally supplied on two or three pole units. switch is located in the right-hand pole (viewed from terminal end) unless otherwise specied. 1 2 3 4 iel 1 - 1rec4- 61- 20.0 - 01 - v 5 7 example: black yellow red blue green orange white -00 -10 -20 -30 -40 -60 -90 -01 (std) -11 -21 -31 -41 -61 -91 seventh decision 7 handle color and marking selection ial, iul, iel, ialh, iulh, ielh - toggle handle marked* on-off color unmarked i-o fifth decision 5 rated current use three numbers to print required current value between .100 amps minimum and 100 amps maximum. for example, use: .100 or 2.00 or 10.0 the vde (lth) will be 95% of the ul/csa rated current. fourth decision 4 frequency & delay switch only 400hz short delay 400hz long delay 400hz motor start 400hz 150% instant trip dc short delay dc long delay dc motor start dc 125% instant trip 50/60hz short delay 50/60hz long delay 50/60hz motor start 50/60hz 125% instant trip dc/60hz short delay dc/60hz long delay dc/60hz motor start dc/60 hz 135% instant trip for addition of inertial delay, add an f?
