Hydraulic Magnetic Circuit Protectors

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. In

addition, they are UL Recognized as supplementary protectors per UL

STD. 1077, CSA Certified as supplementary protectors per CSA C22.2–

No. 235, TUV Approved to IEC60947-2, 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 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.
