ABSTRACT:
A miniature cartridge-type fuse comprises a sub-assembly of an inner insulating housing made of a transparent glass or glass-like material which cannot withstand the forces of a short circuit overload, and end cap terminals at the ends of the housing. A transparent encapsulating body is preferably molded immovably around the inner housing and covers, seals and physically interconnects the exposed exterior surfaces of the inner housing and terminals. The encapsulating body prevents the hazardous destruction of the fuse under all overload conditions and enables the fuse element to be seen through the encapsulation body and inner housing.
