The TPEL TH198 HOL thermal fuse is a non-resettable overtemperature protection device. When the temperature at the fuse body reaches 198°C, the element opens permanently, disconnecting the circuit to prevent heat damage or fire. It is designed for installation inside transformers, electric fans, low-power motors, chargers, electronic ballasts, capacitors, and various heating systems.

Rated at 250V AC and 10A, it is compatible with the majority of single-phase low-power equipment. The 170°C holding temperature ensures the fuse remains closed throughout normal operating cycles that approach, but do not reach, the trip point.
