Product Description
Thermal Fuse Thermal Switch Temperature Switch Temperature Controller
H20, H21 series universal and enhanced protectors with large metal casing are composed of thermal conductive metal casing, bimetallic parts welded with silver alloy contact point, 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 safe operating temperature, the contact point automatically closes to resume normal operation.

H20, H21 Series Temperature Protector Applications
H20, H21 series are suitable for chargeable batteries, ballasts, massagers, micro motors, transformers, electric tools, heat electric appliances and instruments.
Operation Types
Manual Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it quickly disconnects. The contact point cannot reset until the circuit is manually reconnected by pushing the reset button when temperature declines to a fixed point.
Automatic Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it quickly disconnects. The contact point automatically resets when temperature declines to a fixed point.
Note for Manual Reset Type:
- This type can reset when temperature declines 20°C after snap action by pressing the reset button (4~6 N force recommended).
- For normal function, the distance between reset button and close cover should not be less than 20.4mm.
Product has UL, CQC, TUV and RoHS certification approval.
