![]() It is used in different temperatures with different properties. These are available in a wide range of electric currents. These fuses are available in lightweight with specific parameters. This fuse protects the motor’s starting as well as other devices against overload and short circuits. ![]() This provides protection in situations like overload and short circuits. NH-type fuse is used for low and medium voltage. There are usually 3 types of fuses that are listed below: HRC, therefore, has reason to provide limitations within the element of the fuse.Īlso Read: What Is Fuse? | Types of Fuses | Working Principle of Fuse | Application of Fuse Types of HRC fuse: And it will break before the eutectic material. The thinner parts of the fuse element melt faster in a smaller area when the fuse is in a short circuit condition. When the fuse is in an overload condition the fuse ingredient does not melt but if such a condition lasts for a long time then a material like eutectic will melt and break the fuse element. If more current passes than its limit the fault current melts the element of the fuse before it reaches its climax. Under normal conditions, the current does not generate enough heat to dissolve it. The melting point of tin is 2400° C which is less than the melting point of silver like 980° C thus melting point of tin joints prevents the fuse from getting high temperatures in case of short circuits and overload. 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 silver currently. ![]() Metal-end caps are added to this ceramic body. The HRC fuse is made of a material that has a highly heat-resistant body like ceramic. Similarly, if the fault current is not high, the break time is long. The HRC fuse is uniform and 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. 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. ![]()
