    Abstract: An electric fuse for elevated circuit voltages has a plurality of ribbon fuse links connected in parallel. The fuse is designed to have full range interrupting or clearing capacity, i.e., to be able to interrupt small currents but slightly in excess of its minimum fusing current up to the largest major fault currents that may occur in distribution systems at points close to the source of power. This is achieved mainly by mounting on each of said plurality of fuse links a plurality of pellets of a gas evolving material, each of said plurality of fuse links having a metal-severing low fusing point overlay covered by one of said plurality of pellets and each of said plurality of fuse links being threaded through and supporting pellets of a gas evolving material which are positioned at points where there is no metalsevering low fusing point overlay.

    Abstract: A high-voltage fuse for interrupting both protracted overload currents and major fault currents and operating as a currentlimiting fuse when interrupting major fault currents. The fuse includes one or more fusible elements each operating in the fashion of a composite fusible element including serially connected ribbon sections and a wire section interposed between, and spot-welded to, the ribbon sections. In fuses according to this invention one single stamping, i.e. one single length of sheet silver stock takes the plate of a spot-welded composite of ribbon sections and a wire section. The wire like effect is achieved by providing an oblong hole, or window, in the center region of the ribbon fuse link, resulting in the formation of two wire-like strips of small cross-sectional area to both sides of the oblong hole or window.

    Abstract: A cartridge fuse provided with a blown fuse indicator arranged in coaxial relation with the casing of the fuse and forming an integral part of the fuse. The blown fuse indicator includes an indicator housing arranged in coaxial relation to the casing of the fuse and defining a shoulder abutting against the end surface of one of the pair of terminal caps by which the casing of the fuse is closed. The indicator housing has a sleeve-like extension overlapping the lateral surface of one of said pair of terminal caps and affixed to said one of said pair of terminal caps.
