Schneider Electric Thermal Overload Relay, Adjustable, 690V AC Contact Voltage Rating - TeSys Series - LRD3357
Beat the heat from excess current in your electric motor using this thermal overload relay from Schneider Electric. When it senses a current overload, this unit causes the contacts to change state, keeping power from flowing to the circuit. You can adjust the thermal protection range between 37 and 50A to match the needs of your motors. Thanks to a built-in trip button, you can put this device to the test by simulating tripping to make sure that it's working correctly.
