Low Voltage Motor Protectors

Our Bulletin 193/592 Electronic Overload Relays offer flexibility and convenience in modular designs. They are available for both NEMA and IEC applications. In addition, this portfolio offers a variety of options including protection and communication modules.

Our Bimetallic Thermal Overload Relays are motor protectors for IEC applications. We designed these relays for use with our contactors and reversing contactors.

Bulletin 592 Eutectic Alloy Overload Relays are thermal type devices. When used with the proper short-circuit protection, these relays protect the motor, motor controller, and power wiring against overheating due to excessive overcurrents. The trip-free mechanism provides overload protection even when the reset button is pressed.

Our Bulletin 825-P Modular Protection Systems are discontinued and no longer available for sale. Customers are encouraged to migrate to the E300 Electronic Overload Relays.
