ABSTRACT:
A fuse for operation with both DC and AC currents is disclosed which consists of a composite fuse link contained in a large insulator housing. Located within the housing are first and second foil sections fabricated from a good conducting material. Each foil section is secured to a right and left terminal with its other end coupled to a central link fabricated from zinc. The central link is contained within a smaller cylinder and is surrounded by air, while the foil sections are surrounded by quartz sand or some other suitable filler material dispersed within the large housing.
