CM RELAY THERMAL OVERLOAD 33312959

The Columbus McKinnon thermal overload relay is a device that is used to protect electric motors from overheating. It monitors the current flowing through the motor and trips the circuit if the current exceeds a predetermined level, indicating that the motor is overheating. The relay has a thermal element that responds to the heat generated by the current flowing through the motor, and a set of contacts that open the circuit to shut off power to the motor when the thermal element is activated. The relay can be reset manually once the motor has cooled down. This device can be used in a variety of industrial, commercial and residential applications where protection of electric motor is needed.
