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 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.

Two Pole Protectors
An assembly consisting of two single pole units, having their trip mechanisms internally coupled and with a single toggle handle, forms the IEG11 with
quick-connect D.I.N.-style terminals. 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.
