Product Description
ST-22 SEKI Thermostat KSD9700 Temperature Protector Kw9700 Temperature Controller
The ST-22 SEKI Thermostat KSD9700 is a universal temperature protector featuring a large metal casing. Its construction includes a thermal conductive metal casing, bimetallic parts 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 activate quickly to open the contact point and disconnect the circuit. Normal operation resumes automatically when the device cools to a safe temperature.

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 activates to disconnect the circuit. Requires manual reset by pushing a button after temperature declines 20°C (4-6N force recommended). Minimum 20.4mm clearance required between reset button and cover.
- Auto reset type: Automatically resets and resumes operation when temperature declines to a safe level.
This product holds UL, CQC, TUV and RoHS certifications.
