The Siemens 3RN1012-1CK00 is a robust thermistor motor protection unit designed to safeguard motors from potential overheating. This standard evaluation device is equipped with a single-pole double-throw (SPDT) contact configuration and is suitable for use with a 230 V ac supply voltage. It features a compact design with dimensions of 91 x 22.5 x 102 mm, making it an ideal choice for integration into a variety of control cabinet setups.

This thermistor relay is engineered to monitor the temperature of motors by evaluating the resistance of connected PTC thermistors. Upon detection of a temperature rise beyond the threshold, the device triggers an immediate response to disconnect the motor, thereby preventing damage due to overheating. The unit offers manual, automatic, and remote reset options, providing flexibility in control and reset methods.

The 3RN1012-1CK00 includes an LED display for clear indication of operational status and is housed in an IP20 rated enclosure, ensuring protection against solid objects larger than 12.5 mm. It is designed for straightforward screw terminal connections, facilitating easy installation and maintenance.

This device is a reliable solution for motor protection in industrial applications, where consistent performance and durability are essential. It is particularly suitable for use in environments where precise temperature monitoring and motor protection are critical for the smooth operation of machinery.
