Square Pipe Bolt Connection Type Semiconductor Device Protection Used Fast Fuse

Square Pipe Bolt Connection Type Semiconductor Device Protection Used Fast Fuse

1. Application
This collection fuse is suitable for AC 50Hz, rated voltage to 1000V, rated present to 1250A. It is largely utilised for guarding the electrical circuit from overload and quick-circuits(gG/gL). Due to the fact of distinct melting tablets, it also could derive for guarding the semiconductor gadget and other folks complete established installment from limited-circuit (aR/gR/gs) as well as the electrical motor from quick circuit (aM). The rated breaking ability is to 120KA. They conform to nationwide regular GB13539 and international electrical committee regular IEC60269.

2.CZPT Function
This sequence of fuse is composed of fuse website link, fuse foundation and carrier fuse. The variable cross-area fuse entire body created by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the sq. fusion tube which is made by the large strength porcelain or epoxy glass fabric pipe, there is full of the higher-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 spot welding to reliably hook up with the finish plate(or junction panel) and to type the sq. knife shape get in touch with structure. The fuse may have fuse indicator or striker, when the fuse component fusing it can show fusing (indicator) or transforms every single sort of signal as effectively as computerized transfer circuit (striker). The fuse foundation is composed of substantial temperature resistance resin plate(or large intensity porcelain plate) and wedge-formed static make contact with to form open up-type composition and it can be utilised as the supporting device of the proper size of the fuse hyperlink. This series of fuse has a lot of deserves such as very good in heat dissipation, high mechanical energy, reliable in speak to, convenient in functionality and so on.
