Bimetallic thermostat
Bimetal Thermostat
Model : AT100

The Model AT100 Series snap action thermal protectors feature a shunted design so the bimetallic element does not carry the circuit current, enabling this Bimetal Thermostat to carry larger currents than the conductive thermal protectors. The ultra-small, low-profile cases meet tighter space requirements of smaller battery packs and small DC motors. Three different models feature different lead configurations to meet the needs of many applications.

  • Snap-action design, quick break/quick make switching action.
  • Ultra compact design with a high switching contact rating.
  • Shunted design: Bimetallic element does not carry current. Device makes or breaks circuit primarily based on temperature. This results in reducing the internal heating effect of the device when used in applications with higher current loads.
  • Automatically resets as ambient temperature falls below the calibration set point.
  • Plastic case is electrically isolated from the circuit.
  • Preset calibration temperature; not adjustable in the field.
