Product Details

Siemens Thermistor Motor Protection Relay

The Siemens thermistor motor protection relay is a reliable over temperature protection device that saves motors from overloading. The relay has a mechanism for temperature monitoring or advanced sensing for cutting OFF the power to the motor when it exceeds an initially set threshold. It senses winding temperature to evaluate the motor for overloading or overheating. Just like any other Siemens relay, this motor protection relay guarantees minimum shutdown time, high efficiency and long life.
