The TPEL TH167 HOL thermal fuse is a non-resettable overtemperature protection device. When the temperature at the fuse body reaches 167°C, the element opens permanently, breaking the circuit to prevent heat damage or fire. It is intended for installation in transformers, electric fans, low-power motors, chargers, electronic ballasts, capacitors, and various heating systems.

Rated at 250V AC and 10A, it covers the majority of single-phase low-power appliances. The 146°C holding temperature ensures the fuse remains reliably closed during normal warm-up cycles below the trip threshold.
