1. Application
This series fuse is suitable for AC 50Hz, rated voltage to 1000V, rated recent to 1250A. It is mainly utilized for protecting the electrical circuit towards overload and brief-circuits(gG/gL). Because of different melting tablets, it also may derive for defending the semiconductor gadget and others complete set installment from quick-circuit (aR/gR/gs) as nicely as the electric motor from short circuit (aM). The rated breaking ability is to 120KA. They conform to countrywide common GB13539 and global electrical committee regular IEC60269.
2.CZPT Feature
This series of fuse is made up of fuse url, fuse foundation and carrier fuse. The variable cross-part fuse human body manufactured by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the sq. fusion tube which is made by the higher energy porcelain or epoxy glass fabric pipe, there is complete of the substantial-purity quartz sand processed right after chemistry to take 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 form the sq. knife form contact composition. The fuse could have fuse indicator or striker, when the fuse element fusing it can demonstrate fusing (indicator) or transforms each sort of signal as nicely as automated transfer circuit (striker). The fuse foundation is composed of substantial temperature resistance resin plate(or higher intensity porcelain plate) and wedge-formed static make contact with to form open up-kind construction and it can be employed as the supporting unit of the appropriate dimension of the fuse url. This collection of fuse has a lot of deserves these kinds of as very good in warmth dissipation, higher mechanical power, reputable in contact, convenient in functionality and so on.
