MULTI-POLE CIRCUIT PROTECTORS (IAG/IUG/IEG/CEG/LEG)

Two Pole Protectors

Three Pole and Four 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.

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.
