Product Description
Thermal Fuse Auto Reset Thermal Fuse Thermal Switch Temperature Switch
BW & BH series protectors offer reliable over-current and over-temperature protection with firm sealing, small internal resistance, no noise, and automatic reset functionality. The bimetal components respond to temperature and current changes, altering their state to either cut off or complete the circuit as needed.

BW Series Thermostat Features
1. Principle and Structure
BW series protectors feature large metal casings containing thermal conductive components, bimetallic parts with silver alloy contact points, conductive brackets, insulation stands, fixed contact strips, and heat-resistant cables. When temperature reaches the set value, the bimetallic components quickly open the circuit, automatically resetting when cooled to safe operating temperatures.
2. Specifications
- Switch type: Normally closed or normally opened
- Operating Voltage/Current: AC250V/5A; AC125V/8A
- Operating Temperature: 40~150℃ (5°C increments)
- Tolerance: ±3°C/±5°C/±7°C
- Reset temperature: 15-45°C below operating temperature
- Contact resistance: ≤50mΩ
- Insulation resistance: ≥100mΩ
- Electric strength: AC1500V/1min (no breakdown or flashover)
- Service life: 10000 cycles
3. Dimensions
| Model | Length (mm) | Width (mm) | Height (mm) |
|---|---|---|---|
| BW9700 | 20 | 7.3 | 3.8 |
4. Applications
BW series protectors are suitable for rechargeable batteries, ballasts, massagers, motors, transformers, electric tools, heating appliances, and instruments.
