Claim Text:
1. A medium voltage controllable fuse comprising: a trigger wire comprised of an exothermic reactive intermetallic material, said trigger wire rapidly heating in response to a trigger signal and thereby initiating an exothermic reaction that destroys the trigger wire; a high-current fault interrupting section responsible for opening the fuse and extinguishing arcs in the event of a high-current fault, said high-current fault interrupting section including a first fusible element comprised of a conducting member; a low-current fault interrupting section responsible for opening the fuse and extinguishing arcs in the event of a low-current fault, said low-current fault interrupting section including: a fuse housing defining a chamber for housing the trigger wire, the high-current fault interrupting section, and the low-current fault interrupting section, said fuse housing including a fuse body and a pair of conductive end caps mounted at opposite ends of the fuse body, wherein said high-current and low-current fault interrupting sections are connected in series between the pair of conductive end caps.
