Motor Protection Relays


Mitsubishi Electric thermal overload relays protect motors and motor circuit conductors against over heating caused by current overloads and or phase-loss. The TH-N and TH-T series relays can be paired with the Mitsubishi Electric contactors or utilized as a stand-alone overcurrent protection device.
