Product Details

Siemens Thermistor motor protection relay

The Siemens thermistor motor protection relay is a reliable over temperature protection device to save the motors from overload. This relay has a mechanism for temperature monitoring and advanced sensing for cutting OFF power to the motor when it exceeds a certain initially set threshold. It senses winding temperature to evaluate the motor for overloading or overheating. The ATEX certification provides an extra layer of protection which makes it ideal to function in hazardous environments. Like any other Siemens relay, this motor protection relay guarantees minimum shutdown time, high efficiency and sustainable long life.
