ABSTRACT:
The electrical blade fuse is sealed at both the bottom and the top so that the fuse material, once melted, cannot become dislodged to short out other electrical circuits or to short out the terminals of the fuse itself. A cap of the fuse encloses the fuse cavity and is maintained in position by utilizing tab portions of the fuse terminals which are deformed to hold the cap in place, and additionally to serve as test electrodes to allow testing of the fuse in place.
