Product Description
KW9700 KSD9700 TB02-BB1D TB05-BB5D Thermostat Temperature Controller 9700K
The H20 and H21 series universal and enhanced protectors feature large metal casings composed of thermal conductive metal casing, bimetallic parts welded with silver alloy contact points, conductive bracket, insulation fixation stand, fixed contact strip, and heat resistance cable. In case of abnormal operation, when the environment temperature increases to the set value, the bimetallic parts perform quick action to open the contact point and disconnect the circuit. When cooled to a safe operating temperature, the contact point automatically closes to restore normal operation.

H20/H21 Series Temperature Protector Applications
The H20/H21 series is suitable for chargeable batteries, ballasts, massagers, micro motors, transformers, electric tools, heat electric appliances, and instruments.
Operation Types:
- Manual reset type: When temperature reaches the action range, the bimetallic strip quickly disconnects. The contact point cannot reset automatically - the circuit must be manually reconnected by pressing the reset button after temperature declines by 20°C.
- Auto reset type: The contact point automatically resets and resumes operation when temperature declines to a safe level.
Note: For manual reset models, apply 4-6N force to the reset button. Ensure at least 20.4mm clearance between reset button and cover for proper operation.
This product has UL, CQC, TUV and RoHS certification approval.
