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.
  • 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.
Product Certification:
  • HF series products meet the safety test requirements of IEC 60691 Ed 4.0 and GB/T 9816.2013, and it has certified with UL and other safety approvals.
