ABSTRACT:
A high voltage current limiting fuse is taught which has a plurality of radially oriented, notched, pleated fuse ribbons. The fuse ribbons feed through radial slots in spacers at either end of the fuse barrel. A double fold in the fuse ribbon in the region of the slot in each case provides a locking terminal for abutting the fuse ribbon against the spacer. In addition, the double fold arrangement allows the fuse ribbon to be routed conveniently radially over the edge of the spacer and along the side of the fuse barrel, between the fuse barrel and the inside of a ferrule. This secures the end of the fuse element and provides electrical continuity between the fuse element and the ferrule.
