KSD301 Bimetal Thermostat Temperature Controller with 250V 16A 0-250℃ Range and 100000 Cycles Life

Temperature sensing components consist of bimetallic strips. When temperature reaches the action range, the disc snaps quickly and disconnects the movable contact. The contact cannot reset automatically when temperature declines; instead, the circuit must be reconnected by manually pressing the reset button.

• Reset occurs when temperature declines 20°C after snap action by pressing reset button
• Recommended force: 4-6 N (avoid excessive strength)
• Minimum distance between reset button and cover: 20.4mm for proper function

Temperature sensing components consist of bimetallic strips. When temperature reaches the action range, the disc snaps quickly and disconnects. When temperature declines to the reset point, the contact automatically resets and resumes normal operation.
