This sequence fuse is suited for AC 50Hz, rated voltage to 1000V, rated existing to 1250A. It is largely utilized for safeguarding the electrical circuit in opposition to overload and quick-circuits(gG/gL). Since of different melting tablets, it also may derive for defending the semiconductor device and other folks full established installment from limited-circuit (aR/gR/gs) as effectively as the electric powered motor from quick circuit (aM). The rated breaking potential is to 120KA. They conform to nationwide normal GB13539 and intercontinental electrical committee common IEC60269.
This collection of fuse is made up of fuse website link, fuse foundation and carrier fuse. The variable cross-part fuse entire body produced by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is produced by the substantial strength porcelain or epoxy glass cloth pipe, there is entire of the high-purity quartz sand processed after chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the location welding to reliably join with the finish plate(or junction panel) and to form the sq. knife shape contact structure. The fuse could have fuse indicator or striker, when the fuse aspect fusing it can demonstrate fusing (indicator) or transforms every sort of signal as nicely as automatic transfer circuit (striker). The fuse foundation consists of high temperature resistance resin plate(or high depth porcelain plate) and wedge-shaped static contact to kind open-variety framework and it can be utilized as the supporting device of the proper dimensions of the fuse hyperlink. This collection of fuse has several merits such as great in heat dissipation, high mechanical energy, dependable in contact, practical in efficiency and so on.
