1. Application
This collection fuse is ideal for AC 50Hz, rated voltage to 1000V, rated current to 1250A. It is mostly utilized for protecting the electrical circuit against overload and brief-circuits(gG/gL). Simply because of diverse melting tablets, it also might derive for defending the semiconductor gadget and others total set installment from quick-circuit (aR/gR/gs) as well as the electric powered motor from brief circuit (aM). The rated breaking potential is to 120KA. They conform to national standard GB13539 and international electrical committee standard IEC60269.

two.CZPT Characteristic
This sequence of fuse consists of fuse link, fuse foundation and carrier fuse. The variable cross-area fuse human body created by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is created by the substantial strength porcelain or epoxy glass cloth pipe, there is complete of the large-purity quartz sand processed after chemistry to consider the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably connect with the finish plate(or junction panel) and to sort the square knife form contact framework. The fuse could have fuse indicator or striker, when the fuse component fusing it can exhibit fusing (indicator) or transforms every single sort of sign as well as automated transfer circuit (striker). The fuse base is made up of high temperature resistance resin plate(or large intensity porcelain plate) and wedge-shaped static make contact with to form open up-kind framework and it can be employed as the supporting system of the proper size of the fuse url. This series of fuse has several deserves these kinds of as good in warmth dissipation, large mechanical toughness, trustworthy in get in touch with, convenient in functionality and so on.
