ABSTRACT: An integrally molded current limiting fuse body having surface elongating skirts integrally molded thereto to increase the surface leakage distance may be used in conjunction with various types of end closures for one or both of ends of the fuse body. One type of end closure utilizes a flange member integrally molded around the exterior edge of the fuse body so that an extending edge may be folded over an end plate overlying the open end of the fuse body. Another type of end closure comprises a flange member integrally molded into the edge of the open end of the fuse body so that an extended edge extending beyond the open end of the fuse body can be folded over an end plate overlying the open end of the fuse body. Alter- natively, the extended edge of the flange member may be welded to ? edge of the end plate to securely seal the end plate over the open end of the fuse body. When necessary, a seal may be placed between the end of the fuse body and the end plate to prevent the admission of moisture. Another end closure comprises a metallic end cap having an end wall portion and a flange portion joined to the edge of the end wall portion. The flange portion is integrally molded into the edge of the open end of the fuse body so that the end wall portion overlies and seals the open end of the fuse body.
