THERMISTOR RELAY CM-MSS.41S

Product code
2712512
CM-MSx product series

The CM-MSx.xx product series thermistor relays monitor the temperature of motor windings. Suitable for motors with PTC temperature sensors already installed.

The sensors are located within 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, overload, 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
  • Ability to use in explosive atmospheres
Features
  • Dynamic conductor break detection
  • Wide supply voltage range: 24-240 V AC/DC
  • Short-circuit monitoring of the sensor circuit
  • Fault memory (depending on the device)
  • Reset via automation system, for example
  • Available with screw or spring terminal technology
