A polyphase fuse has a housing shaped substantially prismatically and subdivided into a plurality of chambers each provided for a phase fuse unit, or pole fuse unit, of the polyphase fuse. Each of the chambers contains a pair of terminal bars spaced by the housing itself so as to dispense with additional insulating spacers arranged between each pair of terminal bars. The juxtaposed surfaces of each pair of terminal bars are provided with fuse-link-receiving grooves. Each fuse link means includes a groove-engaging spacing tab and a substantially C-shaped center portion positioned generally transversely to the pair of terminal bars. The fuse link means of each phase unit of the polyphase fuse are superimposed and form a stack, the spacing between the contiguous C-shaped center portions thereof being determined by the length of their spacing tabs.
