The TPEL TH105 HOL thermal fuse is a non-resettable overtemperature protection device. When the temperature at the fuse body reaches 105°C, the element opens permanently, disconnecting the circuit to prevent heat damage or fire. It is designed 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 equipment. The 80°C holding temperature ensures the fuse remains reliably closed during normal warm-up cycles, while still providing protection at a comparatively low trip threshold.
