What is meant by H.R.C fuse?

Answer Posted / amlesh kumar

H.R.C. means 'High Repturing Capacity'.These are similar in construction to cartridge types with the exception that the fuse wire can carry short circuit heavy current for a known time period. During this time if the fault is removed then it does not blow off, otherwise it blow off and breaks the continuity of the circuit. The cartridge(i.e. encloser)of H.R.C. type is either of glass or some other chemical compound and is of air tight construction to avoid the effect of atmospheric air on the fuse material. These are available in 2 to 800Amp-capacity ranges. Fuse element is of silver
