ABSTRACT:
A fuse construction has two spaced electrical conductors with inwardly directed conductor ends. A fuse plate member has opposite plate edges secured to said conductor ends. Said fuse plate has an inner insulative sheet with opposite outer conductive sheet faces. One of the sheet faces has an electric current breaking open band adjacent one conductor and the other sheet face has a similar band adjacent the other conductor. A fusible pin passes through a central part of said insulative sheet and said conductive faces and has its pin ends secured to said conductive faces between said open bands so that said bands do not break the electric current passing between said conductors while the pin does not blow but do break said electric current when the pin blows. A method of assembly of said fuse construction is disclosed.
