PTC Thermistors for Electric Motors


Mod-Tronic PTC Thermistors

  • Reliable PTC thermistors that meet the specifications of DIN 44081 / 44082 provide overheating protection for motors and dynamic monitoring of critical system parameters.
  • MOD-TRONIC PTC thermistors have a very high positive temperature coefficient. Once the motor exceeds the maximum permitted operating temperature, the PTC thermistor will suddenly become highly resistive, and the protection module will switch off the motor. After cooling down (and possibly being reset, depending on the model), the motor is re-enabled via the safety chain and can be restarted.
  • The temperature range is from 60 to 180°C. PTC thermistor beads with different rated response temperatures can be connected in series. This permits optimal and economic thermal protection of machines and windings with different limit temperatures.
  • Mod-tronic PTC Thermistors are both Canadian and U.S. UL Recognized components.
