one. Application
This series fuse is ideal for AC 50Hz, rated voltage to 1000V, rated current to 1250A. It is mostly utilized for protecting the electrical circuit from overload and limited-circuits(gG/gL). Because of distinct melting tablets, it also could derive for defending the semiconductor system and other people complete set installment from limited-circuit (aR/gR/gs) as nicely as the electric powered motor from limited circuit (aM). The rated breaking ability is to 120KA. They conform to nationwide standard GB13539 and global electrical committee standard IEC60269.
two.CZPT Characteristic
This collection of fuse is made up of fuse website link, fuse foundation and provider fuse. The variable cross-area fuse human body made by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is created by the high energy porcelain or epoxy glass cloth pipe, there is entire of the higher-purity quartz sand processed after chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably link with the end plate(or junction panel) and to sort the square knife shape contact structure. The fuse may possibly have fuse indicator or striker, when the fuse component fusing it can exhibit fusing (indicator) or transforms every single variety of sign as properly as automated transfer circuit (striker). The fuse foundation is made up of large temperature resistance resin plate(or higher depth porcelain plate) and wedge-shaped static speak to to kind open up-variety structure and it can be utilized as the supporting unit of the proper dimension of the fuse website link. This collection of fuse has a lot of deserves this sort of as very good in warmth dissipation, substantial mechanical energy, reputable in contact, practical in overall performance and so on.
