1. Application
This collection fuse is ideal for AC 50Hz, rated voltage to 1000V, rated present to 1250A. It is mainly used for guarding the electrical circuit towards overload and short-circuits(gG/gL). Simply because of distinct melting tablets, it also may derive for defending the semiconductor gadget and other people full set installment from limited-circuit (aR/gR/gs) as well as the electrical motor from short circuit (aM). The rated breaking capability is to 120KA. They conform to countrywide standard GB13539 and international electrical committee standard IEC60269.

two.CZPT Characteristic
This series of fuse is made up of fuse website link, fuse foundation and carrier fuse. The variable cross-segment fuse human body manufactured by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the sq. fusion tube which is created by the higher toughness porcelain or epoxy glass fabric pipe, there is full of the substantial-purity quartz sand processed soon after chemistry to just take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably connect with the conclude plate(or junction panel) and to kind the sq. knife form speak to framework. The fuse may possibly have fuse indicator or striker, when the fuse factor fusing it can exhibit fusing (indicator) or transforms every single sort of signal as properly as automated transfer circuit (striker). The fuse foundation is composed of large temperature resistance resin plate(or high intensity porcelain plate) and wedge-shaped static get in touch with to type open-sort construction and it can be employed as the supporting device of the suitable size of the fuse hyperlink. This collection of fuse has several deserves such as excellent in heat dissipation, large mechanical power, reputable in contact, practical in performance and so on.
