Product Details
Siemens 3RN1 Thermistor Relays
3RN1 thermistor relays are a range of thermal protection devices, which when used in conjunction with external PTC thermistors, offer temperature monitoring of electrical drives, transformers and other critical components such as bearings. The 3RN1 range operates on the principle of closed-circuit current and are therefore self monitoring in the event of sensor wire breakage.
