To easily confirm the rating indication of a high voltage cut-out fuse after inserting it in a fuse tube.

A lead wire 2 is passed through a tube 4 indicated with the rating, in this high voltage cut-out fuse. Or, a label 5 indicated with the rating is labeled to the lead wire 2. For another means of solution, the label 5 indicated with the rating is affixed to an arc-extinguishing tube or a coated tube 3, in the high voltage cut-out fuse. For an additional means of solution, the arc- extinguishing tube or the coated tube 3 is lengthened, and the rating indication is provided on a protruded piece 6 formed by shaving the lengthened part, in the high voltage cut-out fuse. For one more means of solution, the arc- extinguishing tube or the coated tube is lengthened, and a groove 8 for the lead wire 2 to pass through is carved in a lengthened protrusion 7, in order to provide the rating indication there.
