A fuse element usually has two or more sections that are connected with the help of a tin. Copper or silver is usually used in fuse due to their low resistance. The chemical reaction will take place between the filling power and the silver vapor, resulting in a high resistance material to help reduce the arc inside the fuse. The heat generated evaporates the dissolved element. Noise Causes The essence cannot overheat within the current. The inside of the fuse body is filled with powder which contains the materials used such as quartz, plaster Paris f Paris, dust, marble, chalk, etc. Which is connected by an element carrying a silver currently. Metal-end caps are added to this ceramic body. The HRC fuse is made of a material that has a high heat-resistant body like a ceramic.

Similarly, if the fault current is not high, the break time is long.Īlso Read : What is Limit switch | Working Principle of Limit switch | Application of Limit switch Construction of HRC Fuse: The HRC fuse is uniform, has the feature that it has a very low tripping time if it has a high-pressure current. There is a large amount of space on the inside of this which is around the wire otherwise the element of the fuse.

The ends of the fuse are made of ceramic metal caps which are attached with flexible silver wire. The fuse is tightly closed to prevent atmospheric air from entering it. HRC fuses are made from glass or some other type of chemical compound.

Definition: The HRC fuse whose full name is the High Rupturing Capacity fuse is similar to a normal fuse in which the fuse wire carries a short circuit current up to a certain limit.
