Abstract

A modular under oil expulsion fuse cartridge assembly includes a tubular housing of non-electrical conductive material, an electrically conductive contact removably threadedly mounted on each end of the housing, and a replaceable fuse assembly removably slidably received within the tubular housing. The fuse assembly includes a fuse support tube and a fuse link supported within the tube electrically connected to each of the end contacts. The end contacts are designed with ramps or tapered ends to prevent arcing along the insulating surface of the fuse housing, and are located on the outside housing surface of the device away from the operating or arcing region of the assembly to provide a maximum strike distance between the end contacts. At least one of the electrical connections of the fuse link includes a plurality of deformable fingers movable between a first position which permits the fuse assembly to be slidably received within the housing, and a second position in which the fingers are spread outwardly by a clamping nut into engagement with an end contact.
