Bimetallic Thermostat KSD9700 with 50-150℃ Range Normally Closed or Open and Bakelite Case

The KSD9700 temperature protector features a robust design with large metal casing, providing reliable thermal protection for various electrical applications.

The H20 and H21 series universal and enhanced protectors consist of a thermal conductive metal casing, bimetallic components welded with silver alloy contact points, conductive bracket, insulation fixation stand, fixed contact strip, and heat resistance cable. During abnormal operation, when environmental temperature reaches the set value, the bimetallic components perform quick action to open the contacts and disconnect the circuit. When cooled to safe operating temperature, the contacts automatically close to restore normal operation.

• CQC Certificate No: CQC16002142880
• TUV Certificate No: B160592241002

H20 and H21 series temperature protectors are suitable for rechargeable batteries, ballasts, massagers, micro motors, transformers, electric tools, heating appliances, and instruments.

Manual Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it jumps quickly and the movable disc disconnects. The contact point cannot reset until reconnecting the circuit by pushing the reset button after temperature declines approximately 20°C. Use 4-6N force for resetting. Ensure at least 20.4mm distance between reset button and close cover for normal function.

Auto Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it jumps quickly and the movable disc disconnects. When temperature declines to a fixed point, the contact point automatically resets and resumes operation.

This product holds UL, CQC, TUV, and RoHS certification approvals.
