Abstract
An 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 received within the tubular housing. One of the end contacts incorporates a pressure chamber providing a flushing and cleaning operation during the interruption process. The fuse assembly includes a fuse liner tube in a fuse link therein in the form of a flat ribbon element electrially connected to each of the end contacts. One end of the fuse link is mounted on a thin disc which includes a plurality of projecting lands that prevent direct engagement of the fuse link with the end contact to avoid breaking the fuse link. The fuse link also includes a plurality of holes formed therethrough covered by a eutectic material having a desired melting temperature so that current interruption occurs at a predetermined operating temperature.
