They are capable of clearing high as well as low currents. Once the overcurrent damages and melts the fuse thread, we can simply eliminate t he Fuse Carrier as well as put back the fuse wire. Fuses work on the principal of a large current melting the fuse wire. These types of fuses include two essential parts where those are a fuse base, which has two terminals like in and out. The base contains the incoming and outgoing terminals. No maintenance required. Advantages: Fuse is cheapest type of protection in an electrical circuit; Fuse needs zero maintenance; Operation of fuse is simple and no complexity is involved ; Fuse has the ability to interrupt enormous short circuit current without producing noise, flame, gas or smoke; The operation time of fuse can be made much smaller than operation of circuit breaker. Circuit-breakers offer the following advantages compared to fuses. Rewirable Fuses. It also has a separate holder called the fuse base which holds the fuse carrier.. The incoming and outgoing live or phase wires are also connected permanently with the help of connecting terminals to the base. The wire is threaded through a small hole in the porcelain or ceramic fuse carrier (bridge) and secured to the contacts (terminals) by means of screws. Quick operation. Fuses have the advantages of being inexpensive, readily available and easily replaced. In some cases faults can occur in which the current may not be large enough to melt the fuse but enough to seriously harm the user of the electrical appliance. Their disadvantages are being inadequate to safely, efficiently assume the load of many modern electrical systems and difficult to identify once blown. … High breaking capacity. Their inverse time characteristic makes them much suited for overload protection. In general, this element is fabricated with Porcelain. Advantages of HRC fuses. the rewirable fuse. Homes with electrical systems installed prior to 1965 typically use fuses as electric-overload protection. Simple and easy to install. In the light of the working of the automatic fuse and its advantages, it can be concluded that the automatic fuse is a better one than the rewirable, resettable and reclose fuses. Another part of this rewirable fuse is a fuse carrier. They are consistent in performance. Rewirable fuse is the most commonly used fuse in house wiring. It consists of a base and a fuse carrier made of porcelain. When compared to other circuit interrupters of same capacity HRC fuses are the cheaper one. The fuse carrier is inserted into the base to close the circuit. Circuit breakers prevent over-current conditions from overheating wiring or output devices, which could otherwise cause damage or fires. Rewirable fuses come under the classification of LV fuses, and those are almost used in small applications such as wiring in the house, small-scale industries, and other tiny current applications. This is the conductive thread made using aluminium, tinned copper, and lead. For protection against faults of this nature a circuit-breaker is used in place of a fuse. The fuse element is fixed on the fuse carrier. Unlike self-destructive fuses, circuit breakers can open a circuit without requiring replacement. It is also known as kit-kat fuse.
