1. An electric fuse comprising:
- (a) a casing of electric insulating material,(b) terminal caps disposed on the ends of the casing,(c) fusible element means arranged inside said casing and electrically interconnecting said terminal elements,(d) a plurality of differing arc quenching materials arranged in layers within said casing and embedding said fusible element means, and(e) electrically insulative barrier means introduced in a fluid state between said layers so as to conform to the geometry of said fusible element means and to the surface of said layers and thereby establish an essentially impermeable barrier between said layers.

Abstract
A dual element fusible device is provided utilizing a plurality of separate arc quenching fillers disposed in layers within the fuse casing and being effectively separated from one another by an electrically insulative material which is introduced into the casing in a fluid state so that regardless of the configuration of the internal workings of the fuse, it establishes a continuous and impermeable barrier between the respective layers.
