IUGN/ILUN Series
Meets Mil-PRF-555629
The IUGN/IUGN series features:
- A silicone rubber sealed toggle assures firm seal even in harsh environments.
- Available in one to three poles with ratings of .050 to 50 amps.
The IULN series is the "C" frameversion and is available in one to three poles with rating up to 100 amps.
*Optional Handle may be in Pole 2 instead of Pole 1
Panel Mounting Detail: Tolerance plus/minus .005(.13) unless noted.
| IAG/IUG/IEG/CEG Specifications | |
|---|---|
| Trip Free | Trips open on overload, even when forcibly held in the ON position thus preventing damage to the circuit. |
| Trip Indication | Operating handle moves positively to the OFF position upon overload. |
| Ambient Operation | IAG/IUG/IEG/CEG breakers operate in temperatures between -40° C to +85°C. |
| Insulation Resistance | Not less than 100 megohms at 500 volts DC. |
| Dielectric Strength | IAG/IUG/IEG/CEG breakers withstand 3750Vac; 60Hz for 60 seconds between all electrically isolated terminals, except auxiliary switch terminals shall withstand 600Vac, 60Hz for REG and REC types. Four terminal dual coil and relay constructions (not offered in the IEG) will withstand 1500Vac. |
| Endurance | Operates as a switch, the operating life exceeds 10,000 operations at a rate of 6 per minute when tested as follows: 6000 OPS @ rated current plus 4000 OPS @ no load. |
| Electrical Characteristics | .50–50 amperes; 80Vdc Max, 240Vac Max, 50/60Hz and .050–30 amperes: 250Vac Max, 400Hz. Units above 30 amps are not suitable for across-the-line motor starting. |
| Auxiliary Switch | When supplied shall be SPDT configuration. Non VDE approved switches have a maximum UL rating of 10.0 amperes, 250 volts, 60Hz; 3.0 amperes, 50 volts DC, 1 amperes, 80 volts DC (REC) type or 0.1 amperes, 125 volts, 60 Hz. (REG type). VDE approved switches have a maximum UL rating of 10.0 amperes, 250 volts, 60Hz, 1 amperes, 80 volts DC (REG type); or 0.1 amperes, 125 volts, 60 Hz (REG type); or 0.1 amperes, 125 volts, 60Hz (REG type). |
| Moisture Resistance | Meets all the requirements of MIL-PRF-55629 when tested in accordance with Method 106 of MIL-STD-202. |
| Salt Spray (Corrosion) | Meets the requirements of MIL-PRF-55629 when tested in accordance with Method 101 of MIL-STD-202. |
| Shock | Will not trip when tested per MIL-STD-202, Method 213, Test Condition I with 100% rated current applied to delayed units, except 90% current in plane 4 (i.e., handle down). Instantaneous units will have 80% rated current applied in all planes. |
| Vibration | Will not trip when vibrated per MIL-STD-202, Method 204, Test Condition A with 100% rated current applied to delayed units and 80% rated current to instantaneous units. |
| Construction | Series shunt relay and series with auxiliary switch available in various delays and combinations. |
| VDE Approval | IEG is VDE approved under VDE 0642 (EN60934). The IEG has 8mm creepage and clearance between the main circuit and the following areas:
In addition, all VDE approved units will be in compliance with specific CE Directives. These units will be marked as CE Compliant. |
| UL 1500 Recognized | IDG/IDGH is approved for Marine Ignition Protection rated at 65Vdc or 125/250Vac to 30 amperes with 1000 amperes maximum interrupt capacity. |
| UL489A Listed | The CEG is dimensionally the same as the popular IEG, but provides UL listing to UL489A. Available in one to three poles, in series, series with auxiliary switch, shunt, dual coil and voltage trip configurations. As a circuit breaker, the CEG provides communication equipment manufacturers with a UL listed circuit breaker in a very compact package that meets the stringent environmental requirements of today’s marketplace. This makes the CEG ideal for switching, transmission and wireless applications. |
