In general, a fuse is to quickly cut off the supply of power when an electrical component is overloaded in supplying power from an electrical source such as a battery to an electrical component.

Among these fuses, there are those used in electric components where high voltage is used. A fuse used at a high voltage may give a secondary impact to the electric parts as power is transmitted to the electric parts through an arc generated when the melting part of the fuse is cut off due to an overload.

In order to solve this problem, it is necessary to cut off the arc generated when the fusing part is cut in the fuse used at high voltage.

Such a conventional high-voltage fuse is composed of a cylindrical housing, a pair of caps, and an element disposed inside the housing. The element is disposed inside the housing.
