G4 G5 Emerson Microtemp Thermal Fuse Equivalent AUPO HF Series 20A 250V Cutoff 121C 133C 142C 157C 172C 184C 192C 216C 229C 240C

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.Designed for higher voltage and current applications, the HF Thermal Fuse is rated for operating currents up to 20 amps @ 250 VAC. The internal construction of the HF is designed for interrupting higher currents and withstanding higher temperatures than other models.

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.

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.
