Abstract (en)

[origin: US4855705A] A high power current-limiting fuse comprises a cylindrical envelope which closely surrounds a metallic fusible element in the form of a wire or ribbon. The cylindrical envelope is made of high density rigid ceramic such as Alumina of formula Al2O3, and Beryllium oxide of formula BeO. The two ends of the envelope are metallized to form two terminals respectively connected to the ends of the fusible element, whereby the current-limiting fuse is connectable to an electric circuit to be protected through the two so formed terminals. A sheath of fiberglass or ceramic can be mounted around the cylindrical envelope so as to increase the mechanical rigidity of the current-limiting fuse.
