advantages of rewirable fuse

Fuses have the advantages of being inexpensive, readily available and easily replaced. For protection against faults of this nature a circuit-breaker is used in place of a fuse. Their inverse time characteristic makes them much suited for overload protection. They are capable of clearing high as well as low currents. Unlike self-destructive fuses, circuit breakers can open a circuit without requiring replacement. Quick operation. Rewirable Fuses. Fuses work on the principal of a large current melting the fuse wire. 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. Advantages of HRC fuses. 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. High breaking capacity. This is the conductive thread made using aluminium, tinned copper, and lead. Simple and easy to install. 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. Another part of this rewirable fuse is a fuse carrier. The fuse element is fixed on the fuse carrier. 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. … Their disadvantages are being inadequate to safely, efficiently assume the load of many modern electrical systems and difficult to identify once blown. The incoming and outgoing live or phase wires are also connected permanently with the help of connecting terminals to the base. the rewirable fuse. It is also known as kit-kat fuse. Circuit breakers prevent over-current conditions from overheating wiring or output devices, which could otherwise cause damage or fires. They are consistent in performance. The base contains the incoming and outgoing terminals. When compared to other circuit interrupters of same capacity HRC fuses are the cheaper one. 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. The fuse carrier is inserted into the base to close the circuit. It also has a separate holder called the fuse base which holds the fuse carrier.. It consists of a base and a fuse carrier made of porcelain. Rewirable fuse is the most commonly used fuse in house wiring. These types of fuses include two essential parts where those are a fuse base, which has two terminals like in and out. Homes with electrical systems installed prior to 1965 typically use fuses as electric-overload protection. Circuit-breakers offer the following advantages compared to fuses. In general, this element is fabricated with Porcelain. No maintenance required. 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.
