Product Description:
- AUPO HF series product is non-resettable pellet type thermal fuse which prevents electrical appliances from overheating. It has a metal case with pellet material inside and could be used in high current circuits.
Advantages:
- 1. Unique pellet formula technology to ensure stable operation and high precision.
- 2. Complete product quality management system to ensure high consistency and reliability of products.
- 3. Metal casing design, high sensitivity to temperature rise.
- 4. Patented product with strong circuit breaking capacity.
- 5. It is suitable for circuit over temperature protection with rated voltage of 250V and rated current of 20A.
Working Principle:
- When ambient temperature rises to its operating temperature, the pellet will melt, and the spring a can be released to push the star contact that there is no contact with the pin, thus cutting off the circuit permanently.
Application Field:
- HF series is widely used for overheating protection of automotive air conditioners and household appliances such as air conditioners and bath heater.
