Model features introduced

SIRIUS3RN1010//11 thermistor motor protection relay

Conforms to the closed circuit current working principle (monostable design), so it can self-monitor line breakage and trigger electrical separation in the event of a fault in the control voltage, for equipment with AC control voltage total width 22.5mm screw connection 3RN1 thermistor motor protection device is a thermal protection device, suitable for use in combination with A type PTC resistors (cold wires), used to monitor the temperature of electrical drives, transformer windings, oil, bearings, air, etc.

Siemens3RN1 thermistor relay
The 3RN1 thermistor relay is a set of overtemperature protection devices that can be used with an external PTC thermistor to provide temperature monitoring of electrical drives, transformers, and other critical components such as bearings. The 3RN1 series operates according to the closed-circuit current principle, so it can be self-monitored in the event of a disconnection of the sensor line.
