Manual Reset: Temperature sensing components consist of bimetallic strip. When temperature reaches action range, it disconnects quickly. Requires manual reset button press (4-6N force) after temperature declines 20°C from snap action point.
Auto Reset: Automatically resets when temperature declines to fixed point after disconnection.
The JUC-31F thermostat is ideal for:
- Electric equipment and household appliances
- Thermal overload protection in circuit boards
- Power supplies (communication, switching, UPS, medical)
