Abstract
There is disclosed an arcless fuse in which adverse effects on an equipment due to an arc discharge, produced when the fuse is melted, are prevented, and also melted metal is prevented from dissipating. An arcless fuse includes a fuse element 25 having opposite ends connected respectively to a pair of terminals 23 and 23, the fuse element being in the form of one of a wire and a strip. A part of the fuse element 25 intermediate the opposite ends thereof is formed into such a non-linear configuration that a plurality of portions are arranged in closely spaced relation to one another, and the fuse element 25 is molded in a housing 27 of a synthetic resin. Preferably, an amorphous resin is used as the synthetic resin molding the fuse element 25 therein.
