Abstract: A current-limiting fuse structure comprising a generally tubular, electrically insulating casing having terminal means disposed adjacent to the opposite ends thereof. An electrically insulating core is disposed in the casing with opposite ends adjacent to the respective terminal means. One or more fusible elements connected between the terminal means and disposed in a helical path on the core. The core comprises opening means that extend longitudinally thereof for a distance equal to at least one-half of a helical cycle of the fusible elements whereby leakage paths through the core are eliminated.

Abstract: A fuse comprising an electrically insulating, generally tubular casing having a pair of terminal members mounted on the casing adjacent to the opposite ends of the casing and one or more fusible elements connected between the terminal members. A plunger is disposed in an axially extending opening in one of the terminal members and is biased outwardly from the opening by an associated spring. The plunger is normally restrained from movement under the influence of the spring by a restraining wire or high resistance fusible element which is connected between the plunger and the other terminal member of the fuse.
