Motor Protection PTC Thermistors

ATC Semitec stock a full range of motor protection PTC thermistors.  At its thermal switching point (Ts), the PTC resistance increases dramatically from a few hundred ohms to several thousand ohms over a few degrees, allowing the PTC to act as a solid-state thermal switch to trigger an electronic circuit used to switch off.

  • Temperature switch points: 60°C to 190°C in 10K steps
  • Max Voltage: 30VDC
  • Standard Lead Length: 200mm
