TEMPERATURE MONITORING RELAY CM-MSS.23S

CM-MSx product series The thermistor relays of the CM-MSx.xx product series monitor the temperature of motor windings. Suitable for motors with PTC temperature sensors already installed. The sensors are located in the motor windings and directly measure the motor temperature. Thanks to direct temperature measurement, the thermistor relays can assess the motor condition, such as overheating, overloading, and insufficient cooling. Depending on the model and with ATEX approval, the relays can also be used in explosive atmospheres. Benefits • Reliable motor operation • Easy condition indication and fault diagnosis • Option for use in explosive atmospheres Features • Dynamic wire break detection • Wide supply voltage range: 24–240 V AC/DC • Sensor circuit short-circuit monitoring • Fault memory (depending on the device) • Reset via automation system, for example • Available with screw or spring terminal technology This product description is an automated translation of the original Finnish description.
