Product Description
ST-22 SEKI Temperature Controller KSD9700 Thermostat BW-ABS Bimetallic Thermostat
The H20/H21 series universal and enhanced protectors feature large metal casings 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. During abnormal operation, when environment temperature reaches the set value, the bimetallic parts perform quick action to open the contact point and disconnect the circuit. When cooled to safe operation 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.
Manual Reset Type Operation
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 cannot reset until reconnecting the circuit by pushing the reset button.
Note: This manual reset thermostat can reset when temperature declines 20°C after snap action by pressing the reset button (4-6 N recommended). Ensure at least 20.4mm distance between reset button and close cover for proper function.
Certifications: UL, CQC, TUV and RoHS compliant
