High Quality Screw Base Fuse

High Quality Screw Base Fuse

1. Application
This sequence fuse is appropriate for AC 50Hz, rated voltage to 1000V, rated current to 1250A. It is largely used for defending the electrical circuit from overload and quick-circuits(gG/gL). Because of different melting tablets, it also might derive for guarding the semiconductor system and other folks complete established installment from limited-circuit (aR/gR/gs) as nicely as the electric powered motor from short circuit (aM). The rated breaking potential is to 120KA. They conform to national standard GB13539 and global electrical committee standard IEC60269.

two.CZPT Characteristic
This series of fuse is made up of fuse website link, fuse base and carrier fuse. The variable cross-section fuse entire body produced by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is created by the large toughness porcelain or epoxy glass cloth pipe, there is complete of the substantial-purity quartz sand processed right after chemistry to get the extinguishing of arc medium in the tube. The two sides of the fuse use the location welding to reliably hook up with the finish plate(or junction panel) and to type the sq. knife form make contact with construction. The fuse could have fuse indicator or striker, when the fuse factor fusing it can display fusing (indicator) or transforms every single sort of sign as properly as automatic transfer circuit (striker). The fuse base is made up of large temperature resistance resin plate(or substantial depth porcelain plate) and wedge-formed static contact to kind open up-kind structure and it can be used as the supporting system of the proper size of the fuse website link. This collection of fuse has many merits this sort of as excellent in heat dissipation, substantial mechanical power, trustworthy in contact, convenient in efficiency and so on.
