Manual Reset Operation

The manual reset type features temperature sensing components consisting of bimetallic strips. When temperature reaches the action range, the mechanism quickly disconnects. The circuit remains open until manually reset by pressing the reset button when temperature declines by approximately 20°C.

Important Notes:
  1. Apply 4-6N of force when resetting - excessive force may damage the mechanism
  2. Maintain minimum 20.4mm clearance between reset button and enclosure for proper operation
