ABSTRACT:
A protective fuse assembly for a current limiting fuse of the type, including a dielectric housing enclosing the fuse, an end cap secured to the lower end of the fuse by a pyrotechnic charge assembly, the end cap supporting the housing on the fuse, an end cap mounted on the upper end of the fuse for centering the housing on the fuse, and an electrically conductive wire connecting the charge to the fuse whereby the charge is detonated when the fuse senses a fault current to release the lower end cap from the fuse so that the housing drops to the bottom of the fuse.
