Temperature differences which affect fuses and other thermal devices are not a concern. IEG models meet IEC spacing requirements which is mandatory for equipment that must comply with IEC specifications 601 and 950 and VDE specifications 0804 and 0805. In addition, they are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA C22.2–No. 235, VDE Approved to VDE 0642 (EN60934), CCC Approved and CE Compliant. IAG models are for those applications where the unit’s inherent attributes are desired, but compliance with the various standards is not required. Designed using the latest in sensitive hydraulic magnetic technology, the IAG/IUG/IEG/CEG/LEG line adapts itself to many applications and environments. They’re ideal for data processing and business machines, medical instrumentation, broadcast One important feature of this protector line is a “trip free” action, which means the circuit will trip in the presence of an overload even though the handle is held in the ON position. The delay mechanism senses the fault and the contacts open. The IAG/IUG/IEG/CEG/LEG is available in a wide variety of configurations including series, series with auxiliary switch, shunt and relay with a choice of delays and ratings in either DC, 50/60Hz or 400Hz versions. Handles come in seven different colors and international markings are standard. Single or multipole versions are available, with a variety of pole arrangements to meet your specifications. Four pole models require a double toggle handle. Units with a handle per pole come in one through six pole assemblies. _IAG Series - Introduction_ http://airpax.sensata.com **99** ## **SINGLE POLE CIRCUIT PROTECTOR** ## **Single Pole Mounting Detail** **==> picture [164 x 132] intentionally omitted <==** **----- Start of picture text -----**<br> .590<br>[15.00] 2X 6 – 32 THREAD<br>MAX. .140 [3.56] DEEP<br>M3 ISO THD.

Individual poles may differ in ratings, delays and internal connections. An auxiliary switch may be included in either or both poles, allowing you to mix SELV and hazardous voltages. Rugged screw-type terminals can be provided, in which case the designation would be IEG66. The IEGH offers a toggle handle for each pole. LEG type units are avavailable only in one or two pole configurations. ## **Three Pole and Four Pole Protectors** The three pole construction consists of three single pole units assembled with an internal mechanical interlock which actuates all units simultaneously. A single toggle handle operates all three poles for quick and convenient control, or if preferred, a handle per pole is available. The four pole construction consists of four single pole units assembled with an internal mechanical interlock which actuates all units simultaneously. A double toggle handle operates all four poles. The individual poles need not have identical characteristics and any series trip pole may have an auxiliary switch. If screw-type terminals are required, the breaker designation will be IEG666 for a three pole version and IEG6666 for a four pole version. Protector poles are numbered consecutively when viewed from the terminal side, with the ON position up, starting with Pole #1 on the left side and proceeding to the right. **==> picture [203 x 9] intentionally omitted <==** **----- Start of picture text -----**<br> IAG/IUG/IEG/CEG/LEG Multi-Pole Circuit Breakers<br>**----- End of picture text -----**<br> **==> picture [526 x 328] intentionally omitted <==** **----- Start of picture text -----**<br> IAG/IUG/IEG/CEG/LEG<br>1.687 .240 Two Pole* Three Pole* Four Pole*<br>[42.85] [6.10]<br>ON<br>32º<br>ON OFF ON OFF ON OFF ON OFF<br>32º<br>OFF<br>2.075 .690 1.51 5 2.265 3.015<br>[52.71] [17.53] [38.48] [57.53] [76.58]<br>MAX.

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 selfinterrupting) 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 [220 x 440] intentionally omitted <==** **----- Start of picture text -----**<br> .230 2.52 MAX.<br>[5.84] [64.00]<br>(See Note A)<br>1.380<br>[35.05]<br>1.530<br>[38.86] Dual Coil<br>.230 2.52 MAX.<br>[5.84] [64.00]<br>(See Note A)<br>.620<br>[15.75]<br>1.380<br>[35.05]<br>1.530<br>[38.86]<br>Dual Coil<br>Optional Barriers (IEG Only)<br>.571<br>[14.50]<br>2.000<br>[50.80]<br>Note: Tolerance ± .015 [.38] unless noted.<br> Dimensions in brackets [ ] are millimeters.<br>**----- End of picture text -----**<br> _IAG Series - Configurations_ http://airpax.sensata.com **109** ## **TYPICAL RESISTANCE / IMPEDANCE** |**TYPICAL RESISTANCE / IMPEDANCE**|**TYPICAL RESISTANCE / IMPEDANCE**|**TYPICAL RESISTANCE / IMPEDANCE**|**TYPICAL RESISTANCE / IMPEDANCE**| |---|---|---|---| |**Current Ratings**<br>**(Amps)**|**Impedance**||| ||**DC**<br>**(ohms)**|**AC, 50/60Hz**<br>**(ohms)**|**AC, 400Hz**<br>**(ohms)**| ||**_51, 52, 53, 59_**|**_61, 62, 63, 69_**|**_41, 42, 43, 49_**| |0.200|45.8|28.5|71.94| |1.00|1.38|1.10|2.85| |2.00|0.371|0.29|0.76| |5.00|0.055|0.051|0.12| |10.0|0.017|0.016|0.032| |20.0|0.006|0.006|0.010| |30.0|0.003|0.004|0.006| |50.0|0.0019|0.0018|—| |_DCR and Impedance based on 100% rated current applied and stabilized for_<br>_a minimum of one hour.

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. 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 protector 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 following is the code for a single pole, IEG quick-connect type terminal, series unit with auxiliary switch, designed for operation in a 50/60Hz circuit. It has a short time delay, a rating of 20 amperes, a black marked handle and is VDE approved. To determine the ordering number for your particular IAG/IUG/IEG/CEG 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: - A. It is recommended that power leads be soldered to circuit protectors having push-on type terminals for current trip ratings above 20 amperes. - B. When “A” (metric thread mounting) is specified in the sixth decision in combination with screw terminal option in the second decision, metric screw terminals are supplied. - C. IEG, IEGH, IEGS, IEGHS, IEGX and IEGZX circuit protectors are designed to meet 8mm creepage and clearance requirements for installation Category III, Pollution Degree 3, Case A as measured in IEC 664. Intended for use in equipment designed to comply with IEC 601 and 950 and VDE 0804 and 0805. **==> picture [260 x 289] intentionally omitted <==** **----- Start of picture text -----**<br> 1 First Decision<br>Select Type and Terminal<br>Type Description Handle and Mounting Options<br>IAGIUG*IUG* Standard toggle/mounting,<br>IEG** One toggle handle per unit no designation required<br>CUG+ S Toggle w/ snap-in mounting<br>CEG++<br>IAGH X Rocker w/ standard mounting*g**<br>IUGH*IEGH**IEGH** One toggle handle per pole ZX ZX Rocker w/ integral mounting*<br>CUGH+ BX BX Rocker w/ integral mounting<br>CEGH++<br>IDG*** One toggle handle per unit,marine ignition protectionmarine ignition protection Note: Add "F" for flat screw terminals N Sealed toggle w/bushing mounting**<br>IDGH*** One toggle handle per pole * Not available on mid-trip units** Available only on IAG, IUG units** Available only on IAG, IUG units<br>marine ignition protectiongnition protectionnition protectionprotectionrotection<br>IMG** One toggle handle per unit<br>CMG++ mid-trip indication<br>IMGH** One toggle handle per pole 2 Second Decision<br>CMGH++ mid-trip indication Poles and Terminals<br>*UL Recognized, CSA Certified<br>**UL Recognized, CSA Certified, VDE Approved Push-on Screw<br>*** UL Recognized UL1500 Terminals Terminals<br>+ UL489A Listed CSA Certified<br>++ UL489AListed CSA Certified VDE Approved 1 6 Single pole<br>11 66 Two pole<br>111 666 Three pole<br>1111 6666 Four pole<br>*Not available in toggle seal handle type.<br>Example:<br>**----- End of picture text -----**<br> **==> picture [343 x 581] intentionally omitted <==** **----- Start of picture text -----**<br> 1 First Decision<br>Select Type and Terminal<br>Type Description Handle and Mounting Options<br>IAGIUG*IUG* Standard toggle/mounting,<br>IEG** One toggle handle per unit no designation required<br>CUG+ S Toggle w/ snap-in mounting<br>CEG++<br>IAGH X Rocker w/ standard mounting*g**<br>IUGH*IEGH**IEGH** One toggle handle per pole ZX ZX Rocker w/ integral mounting*<br>CUGH+ BX BX Rocker w/ integral mounting<br>CEGH++<br>N Sealed toggle w/bushing mounting**<br>IDG*** One toggle handle per unit,marine ignition protectionmarine ignition protection Note: Add "F" for flat screw terminals<br>IDGH*** One toggle handle per pole * Not available on mid-trip units** Available only on IAG, IUG units** Available only on IAG, IUG units<br>marine ignition protectiongnition protectionnition protectionprotectionrotection<br>IMG** One toggle handle per unit<br>CMG++ mid-trip indication<br>IMGH** One toggle handle per pole 2 Second Decision<br>CMGH++ mid-trip indication Poles and Terminals<br>*UL Recognized, CSA Certified<br>**UL Recognized, CSA Certified, VDE Approved Push-on Screw<br>*** UL Recognized UL1500 Terminals Terminals<br>+ UL489A Listed CSA Certified<br>++ UL489AListed CSA Certified VDE Approved 1 6 Single pole<br>11 66 Two pole<br>111 666 Three pole<br>1111 6666 Four pole<br>*Not available in toggle seal handle type.<br>Example:<br>IEG 1 - 1REC4 - 61 - 20.0 - 01 - V<br>1 2 3 4 5 6 7<br>3 Third Decision 4 Fourth Decision<br>Internal Configuration Frequency and Delay<br>-0 Switch only SW Switch only<br>-1 Series -41 400Hz short delay<br>-1REC4 Series w/ auxiliary switch * -42 400Hz long delay<br>.110 quick connect -43 400Hz motor start<br>-1REC5 Series w/ auxiliary switch * -49 400Hz 150% instant trip<br>.187 quick connect<br>-51 DC short delay*<br>-1REG4 Series w/ auxiliary switch (gold contacts)* -52 DC long delay*<br>.110 quick connect -53 DC motor start*<br>-1RS4 Series w/ alarm switch, -59 DC 125% instant trip*<br>electrical trip,<br>.110 Q.C. terminals -61 50/60Hz short delay<br>-1RLS4 Series w/ alarm switch, -62 50/60Hz long delay<br>electrical trip, -63 50/60Hz motor start<br>.110 Q.C. terminals (mid-trip only)<br>-64 50/60Hz short delay<br>-3 Shunt<br>-65 50/60Hz long delay<br>-4 Relay -66 50/60Hz motor start<br> * Only one auxiliary switch is normally supplied on two or three pole units.

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.
