Thermostat for monitoring temperature of the motor winding

Monitored ranges: 1.8 – 3.3 kohm
Output: 2x CO, 8 A

EAN: 8595188137164 Category:


  • It monitors motor coil temperature.
  • Fixed levels of switching.
  • PTC sensor is used for sensing, it is in-built in motor winding by its manufacturer or there is used an external PTC sensor.
  • MEMORY function – relay is blocked in an error state until until operator intervention (press RESET button).
  • RESET of faulty state:
    a) Button on the front panel.
    b) By external contact (remote by two wires).
  • Terminals of sensor are galvanically separated, they can be shorted out by terminal PE without damaging the device.
