Breaking capacity of a hbc fuse
Breaking capacity or interrupting rating is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration. The prospective short-circuit current that can occur under short circuit conditions should not exceed the rated breaking capacity of the apparatus, otherwise breaking of the current cannot be guaranteed. The current breaking capacity corresponds to a certain voltage, so an electrical … WebOct 30, 2009 · This paper presents the results of arc investigation for a number of materials when they were used as high breaking capacity (HBC) fuse fillers. Aluminum hydro-oxide, boric acid, zinc oxide, titanium oxide, and boron trioxide have been investigated and their prospects as filling media in high-voltage, high breaking capacity fuses have been …
