IEC Thermal Overload Relays

Thermal Overload Relays protect loads from over-current conditions by sensing the load current in all three wires of the load, and kicking out the contactor in the event of an over-current in any leg.  The current trip point is settable from the front panel dial.  The trip may be reset either manually or automatically after a time delay. 

The Cerus line of overloads by Franklin Electric are designed for easy snap-mounting with the Cerus IEC Contactors, or may be mounted separately stand-alone and used with any brand contactor.
