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.
