ABSTRACT:
An electric fuse includes a cylindrical insulating housing with conductive terminal caps at opposing ends of the housing. Conductive ferrules are adjacent the terminal caps and electrically connected thereto. At least one main fusible element is disposed between the terminal caps and electrically connects the terminal caps. The ferrules are of a cylindrical configuration such that the fuse is operational through clip mounting of the ferrules. Bolt receiving means is provided for bolt mounting the fuse between a pair of conductive mounting bus bars. The bolt receiving means comprises a plurality of internally threaded passageways for securely receiving a threaded bolt. Each of the passageways respectively extends generally longitudinally inwardly through each of the terminal caps. The presence of the bolt receiving means presents substantially no impediment to the clip mounting operation of the fuse.
