[0002] A resettable fuse is a device used in electrical systems to protect circuits from overload and short circuit. When the current exceeds the rated current value of the fuse, the fuse will blow, cutting off the circuit and playing a protective role. Traditional fuses need to be replaced once they blow, while resettable fuses can automatically restore power after the fault is eliminated, without the need for replacement; most of the resettable fuses on the market currently have a slow recovery speed after use, resulting in a long wait before they can be used, which affects work efficiency and time to a certain extent. For this reason, we propose a heat-dissipating resettable fuse. Utility Model Content
