Siemens 3RN1010-1CM00 Thermistor Motor Protection Relay 230V AC

The Siemens thermistor motor protection relay 230V AC, also known as a PTC motor protection relay, thermistor relay, or winding protection relay, with type number 3RN1010-1CM00, is an electrical relay for monitoring and protecting electric motors against overheating. It serves as a standard evaluation unit and features an automatic reset function, as well as one normally open (NO) and one normally closed (NC) contact. It is designed for an operating voltage of 230V AC. The device has dimensions of 3 x 10 x 9 cm and weighs 0.17 kg. Thermistor motor protection relays monitor the temperature in motor windings and switch off the motor if a limit value is exceeded, to prevent damage from overheating. Typical applications are found in industrial drives, pumps, fans, and compressors, as well as in process automation and mechanical engineering, to ensure the lifespan and reliability of motors.
