introduction the airpax? iag/iug/ieg/ceg/leg magnetic circuit protectors provide low-cost power switching, reliable circuit protection and accurate circuit control for equipment in the international marketplace. 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 c22.2Cno. 235, vde approved to vde 0642 (en60934), ccc approved and ce compliant. iag models are for those applications where the units 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. theyre ideal for data processing and business machines, medical instrumentation, broadcast equipment, vending and amusement machines, military applications and wherever precision operation is required. temperature differences which affect fuses and other thermal devices are not a concern. 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 multi- pole 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/iug/ieg/ceg/leg series hydraulic magnetic circuit protectors iag series - introduction http://airpax.sensata.com 99
