High Rupture Capacity fuse.
Usually the type of fuse is encoded into the fuse number. For example a English Electric fuse C20J, the C represents that the fuse is a cartridge type, the 20 is the amperage of the fuse and the J represents the speed of the fuse. Also the J states that the fuse is a type J fuse.
Because if it is not connected to both it is not a full circuit and therefore if it is not a full circuit then the fuse can't protect you.
The interruption capacity of a fuse is the ability of a fuse to stop the current flow on a short circuit condition. On high rupture capacity (HRC) fuses the fuse cartridge has silica sand surrounding the fuse link. When the link blows under a high current so much heat is generated that the silica sand actually turns to glass to extinguish the arc. A dual element fuse is used on motor starting circuits. Their construction inside with two current flow paths allow the high current of a motor start for a short interval of time without blowing.

The full form of HRC is Rockwell Hardness C Scale. It is a measure of the hardness of a material, typically metals, determined by how much force is required to create an indentation on the surface of the material.
An ohm meter across the fuse will tell you whether the link is open or closed.
Silica sand is used in an HRC (High Rupturing Capacity) fuse to provide insulation and arc quenching properties. When the fuse blows, the silica sand helps to extinguish the arc created by the breaking circuit, preventing damage to the surrounding equipment.
The main advantage offered by an HRC fuse is that, when a fault current condition occurs, a tremendous amount of heat is created within the fuse. That heat melts the silica sand filling of the fuse into glass. Glass, being an insulator, suppresses any arc-over and breaks the circuit instantaneously. This behavior minimizes the possibility of a continuing - and dangerous - "high arc current" situation from developing, which is what happens if a normal fuse fails to break a heavy fault current. Compared to normal, "non-HRC" fuses, the main disadvantage of using an HRC fuse is that they cost a lot more to make - and to buy - because of the extra materials they contain. But choosing to use an HRC fuse instead of a normal fuse makes very good sense if the equipment that needs to be protected - or other equipment nearby - would be very expensive to replace if it all went up in smoke just because of a fuse which was not capable of stopping a high fault current flowing. So, if some expensive electrical equipment was supplied with one or more HRC fuses installed to protect it, you would be very foolish indeed to replace them with normal "non-HRC" fuses.
semiconductor fuse is used to save the diodes ,thyristers and IGBTS because the below time is very fast in the case of any short circuit and over current, HRC fuse is mostly used in the power factors panels and its below time is less then semiconducter fuses.

HBC (High Breaking Capacity, European term) and HRC (High Rupturing Capacity, North American term) fuses have the ability to break high fault currents. This is done by having silica sand in the fuse that the fuse elements travel through. On high fault current that sand will melt and turn to glass. This breaks the current flow immediatelyA cartridge fuse maximum current breaking capacity is very much lower than HRC, HBC because there is nothing in the fuse body except the fuse elements.
HRC stands for 'high rupture capacity'. An alternative abbreviation is 'HBC, meaning 'high breaking capacity. The rupture (or breaking) capacity is a term describing the maximum short-circuit current that the fuse can safely interrupt at its rated voltage. Most fuses will safely interrupt any level of fault current between a current that just causes the fuse to operate (melt), up to their maximum breaking capacity- such fuses are called 'full-range'. HRC fuses usually have strong, ceramic bodies to withstand the huge pressure generated when the fuse has to interrupt a large short-circuit current. In contrast, low breaking capacity fuses have weaker bodies made from materials such as glass.
