Abstract
The high current interrupting fuse of the invention includes an envelope free of sand or similar arc quenching material. The envelope preferably has terminal end caps enclosing the ends of the envelope between which caps a fuse element extends. The envelope has an arc-quenching gas-releasing material at least at the inner surface of the envelope. Arc barrier plugs made of an ablative material surround each end of the fuse element which for ease of assembly freely pass through bores of plugs. The fuse element also preferably passes through metal plates externally of the plugs and adjacent to the end caps.
