Large power fuses use High Rupture Capacity fuse of fusible elements made of silver, copper or tin to provide stable and predictable performance. High voltage expulsion fuses surround the fusible link with gas-evolving substances, such as boric acid. When the fuse blows, heat from the arc causes the boric acid to evolve large volumes of gases. The associated high pressure and cooling gases rapidly extinguish the resulting arc. The hot gases are then explosively expelled out of the end(s) of the fuse. Other special High Rupturing Capacity (HRC) fuses surround one or more parallel connected fusible links with an energy absorbing material, typically silicon dioxide sand. When the fusible link blows, the sand absorbs energy from the arc, rapidly extinguishing it, creating an artificial fulgurite in the process.

high rupturing capacityfuse

Answer / paul

its a high rupture capacity fuse, the main reason you would
use this is because it can distinguish between high start
up current (from say a motor starting) and short circuit
current

Answer / s.karthik

HRC fuse link is a very common, simple and effective
electrical protection device against over load and short
circuit current. It is so simple device that even an
un-skilled person can handle it.
