    Abstract: A low-voltage fuse, and in particular a low-voltage fuse of the polyphase variety, has a specific array of fusible currentcarrying means arranged between juxtaposed surfaces of a pair of spaced terminal bars. These surfaces are provided with grooves extending in a direction longitudinally of said pair of terminal bars. The aforementioned array of current-carrying means is formed by a plurality of stampings of silver or copper, each including a pair of spaced terminal strips and each further including a plurality of terminal-strip-interconnecting fusible elements in ribbon form. The length of each of said fusible elements of said plurality of stampings exceeds the spacing between said pair of terminal bars. The aforementioned stampings are inserted with the terminal strips thereof into the grooves of said pair of terminal bars in such a way that all constituent fusible elements of each of said plurality of stampings are out of registry with any of the constituent fusible elements of any other of said plurality of stampings. The constituent fusible elements of said stampings are further bent alternately in opposite directions away from the median plane of said pair of terminal bars, thus assuming a substantially C-shaped configuration.

    Abstract: A cartridge fuse with ''''exposed'''' solder joints conductively interconnecting the fusible element means and the terminal caps on the casing of the fuse (as distinguished from a cartridge fuse having ''''blind'''' solder joints serving the same purpose) is provided with a novel kind of ''''exposed'''' solder joints. The axially outer ends of the fusible element means are clamped between the outer surface of the casing and the inner lateral surfaces of the terminal caps. The lateral surfaces of the terminal caps have apertures in registry with the ends of the fusible element means. The apertures form cavities for solder joints conductively connecting the ends of the fusible element means and the terminal caps.

    Abstract: A cartridge fuse includes a main casing and a sub-casing inside the main casing. The sub-casing houses the overload current interrupting means of the fuse and does not contain a pulverulent arc-quenching filler. The space bounded by the inner surface of the main casing and the outer surface of the sub-casing is filled with a pulverulent arc-quenching filler embedding the major fault current interrupting means of the fuse. The sub-casing is closed at least at one end by a pair of discs having juxtaposed rectangular cut-outs and defining a straight narrow slit. The sub-casing, the overload current interrupting means therein and the pair of ribbon fuse link sections extending from both sides of the sub-casing form a self-contained and self-sustaining subassembly which can readily be handled in the process of manufacturing the fuse. The aforementioned ribbon fuse link sections are pre-bent at sharp angles and form jointly with the sub-casing and the parts therein a clip-on unit, i.e. a unit that can simply be clipped on to the main casing without any metalforming operation and without use of any tool.

    Abstract: A high-voltage fuse having a mandrel supporting a plurality of ribbon fuse links wound substantially helically around the mandrel. Each fuse link has relatively short serially related neck portions, and each fuse link has a relatively long neck portion. The relatively long neck portions of the various fuse links are displaced in a direction longitudinally of the mandrel to substantially equalize heat generation by said neck portions along the mandrel.

    Abstract: A polyphase fuse of reduced bulk having ribbon fuse links whose length exceeds the height of the individual chambers or compartments of the casing or housing of the polyphase fuse wherein the fuse links are located. The ribbon fuse links are conductively connected to terminal or conductor strips whose juxtaposed surfaces are-or may be-fully utilized for the arrangement of ribbon fuse links. The terminal strips are individually affixed to the housing of the fuse and insulating spacers between the terminal strips are dispensed with.
