Both are CSA certified and CCC Approved. The IEL is CSA certified as a supplementary protector per CSA C22.2–No. 235. IAL models are for those applications where the unit’s inherent attributes are desired, but compliance with the various standards is not required. 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. 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 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. **147** _IAL Series - Introduction_ http://airpax.sensata.com ## **SINGLE POLE, STANDARD STUD TERMINAL** **==> picture [181 x 150] intentionally omitted <==** **----- Start of picture text -----**<br> (SEE TABLE)<br>.281<br>[7.14] .140<br>(SEE TABLE) [3.56]<br>ON<br>1.940<br>[49.28]<br>.142<br>[3.61] OFF<br>1.859 .690<br>[47.22] [17.53]<br>**----- End of picture text -----**<br> **==> picture [263 x 150] intentionally omitted <==** **----- Start of picture text -----**<br> STUD TERMINAL TYPES<br>Screw Stud Thread Dimension “A” Dimension “B”<br>.510 ± .045 .652 ± .035<br>M6<br>[12.95 ± 1.14] [16.56 ± 0.89]<br>.545 ± .045 .687 ± .035<br>1/4 -20<br>[13.84 ± 1.14] [17.45 ± 0.89]<br>.510 ± .045 .652 ± .035<br>M5<br>[12.95 ± 1.14] [16.56 ± 0.89]<br>.545 ± .045 .687 ± .035<br>10-32<br>[13.84 ± 1.14] [17.45 ± 0.89]<br>**----- End of picture text -----**<br> ## Single Pole ## Mounting Detail **==> picture [506 x 159] intentionally omitted <==** **----- Start of picture text -----**<br> 2X 6-32 THREAD .755<br>.140 [3.56] DEEP [19.18]<br>M3 ISO THD.

The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it’s simultaneously used as an on-off switch. **==> picture [133 x 98] intentionally omitted <==** **----- Start of picture text -----**<br> .281[7.13] Dimension B(See Table)<br>SERIES SWITCH ONLY<br>1.940<br>[49.28]<br>Dimension A<br>(See Table)<br>**----- End of picture text -----**<br> 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. ## **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. **==> picture [151 x 80] intentionally omitted <==** **----- Start of picture text -----**<br> .648<br>[16.46]<br>C<br>NO<br>1.055 NC<br>1.290 [26.80]<br>[32.77] BREAKER IN OFF POSITION<br>**----- End of picture text -----**<br> **==> picture [263 x 150] intentionally omitted <==** **----- Start of picture text -----**<br> STUD TERMINAL TYPES<br>Screw Stud Thread Dimension “A” Dimension “B”<br>.510 ± .045 .652 ± .035<br>M6<br>[12.95 ± 1.14] [16.56 ± 0.89]<br>.545 ± .045 .687 ± .035<br>1/4 -20<br>[13.84 ± 1.14] [17.45 ± 0.89]<br>.510 ± .045 .652 ± .035<br>M5<br>[12.95 ± 1.14] [16.56 ± 0.89]<br>.545 ± .045 .687 ± .035<br>10-32<br>[13.84 ± 1.14] [17.45 ± 0.89]<br>**----- End of picture text -----**<br> Shunt and Dual Coil ## **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. ## Note: - A Terminal protrusion dimensions are referenced from back of mounting panel. - B Each screw terminal is supplied with a 10-32x.312[7.92] or M5 x 8mm screw, flatwasher and external tooth lockwasher. - C Stud terminals are supplied with a flatwasher, external tooth lock washer and a 10-32 or M5 hex nut (<=70A), 1/4-20 or M6 hex nut (>70A). **==> picture [92 x 109] intentionally omitted <==** **----- Start of picture text -----**<br> Dimension B<br>.278 (See Table)<br>[7.05]<br>1.26 .660 ±.045<br>[32.00] [16.76] ±1.14]<br>1.940<br>[49.28]<br>.795<br>[20.19] 2.640 MAX.<br>[67.06]<br>(SEE NOTE A)<br>**----- End of picture text -----**<br> **==> picture [48 x 119] intentionally omitted <==** **==> picture [252 x 123] intentionally omitted <==** **----- Start of picture text -----**<br> SHUNT DUAL COIL<br>Spacing for V D E S witch<br>2.454 MAX.<br>.187 [64.52]<br>[4.75] (SEE NOTE A)<br>[24.6.971 6] [17.17] .676<br>[32.16]1.266 -IREC5 .250[6.35]<br>2.438 MAX.<br>[2.79].110 [64.52](SEE NOTE A)<br>.260<br>Note: Each outer terminal is supplied with a flatwasher, tooth lockwasher and a hex nut. -IREC4, -IREG4[6.60]<br>**----- End of picture text -----**<br> _IAL Series - Configurations_ **154** **==> picture [612 x 60] intentionally omitted <==** ## **CONFIGURATIONS (CONT.)** ## **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. **==> picture [250 x 211] intentionally omitted <==** **----- Start of picture text -----**<br> FIG.1 FIG.2<br>Barriers<br>1.378<br>1.098 [35.00] .303<br>[27.89] .952 [7.69]<br>.670 .122 [24.18]<br>[17.02] [3.11]<br>3.100<br>2.740 [78.74]<br>[69.60]<br>FIG.3 FIG.4<br>**----- End of picture text -----**<br> **==> picture [531 x 418] intentionally omitted <==** **----- Start of picture text -----**<br> Relay and Dual Coil<br>.795<br>.660[20.19] [±.045] [29.13]1.147 [29.13]1.147<br>.281 [16.76±1.14] [18.31].721 [.84].033 [18.31].721 [.84].033<br>[7.14]<br>.722<br>1.330 [18.34] [65.02]2.560 [65.02]2.560<br>[33.78]<br>1.940<br>[49.28]<br>NOTE:<br>THIS BARRIER CAN BE FLIPPED<br>TO COVER EITHER POLE.<br>2.640 MAX PLEASE CONTACT FACTORY FOR SPECIFIC PART NUMBER<br>BARRIER OPTIONS<br>Standard Optional<br>Rating Option<br>Barrier Barrier<br>RELAY DUAL COIL IEL<br>240/415 VAC<br>415 VAC (VDE)<br>Fig. 1 Fig. 2, 3 & 4<br>Notes: 277/480 VAC<br>Tolerance ± .015 [.39] unless noted.

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.

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.

Additionally, it is standard policy to establish a factoryassigned 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.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
