Siemens 3RN1013-1BW10 Motor Protection Relay

Siemens 3RN1013-1BW10 Thermistor Motor Protection Relay provides DPDT protection for motors equipped with external thermistors, triggering on winding overheating to prevent damage and enabling safe shutdown in automation panels. It accepts 24 to 240 V AC/DC input with a nominal power consumption of about 2 W and offers DPDT contacts for signaling and control. This device is designed for industrial motor protection in control panels and motor control centers, working with thermistor sensor networks to monitor winding temperature and protect critical equipment. Siemens identifies 3RN2013-1BW30 as the preferred successor, indicating the product line’s ongoing evolution while preserving similar thermal protection functionality and power range.
