NT collection fuse Foundation is suitable for AC 50Hz, rated voltage to 1000V, rated present to 1250A. It is primarily used for protecting the electrical circuit from overload and limited-circuits(gG/gL). Since of distinct melting tablets, it also might derive for defending the semiconductor gadget and other people comprehensive established installment from quick-circuit (aR/gR/gs) as nicely as the electric powered motor from quick circuit (aM). The rated breaking capability is to 120KA. They conform to nationwide standard GB13539 and global electrical committee normal IEC60269.
This series of fuse consists of fuse website link, fuse foundation and provider fuse. The variable cross-part fuse human body created by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the sq. fusion tube which is manufactured by the high strength porcelain or epoxy glass fabric pipe, there is complete of the higher-purity quartz sand processed following 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 end plate(or junction panel) and to sort 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 each and every type of sign as effectively as automatic transfer circuit (striker). The fuse base is composed of large temperature resistance resin plate(or substantial intensity porcelain plate) and wedge-shaped static contact to type open-sort construction and it can be used as the supporting gadget of the appropriate dimension of the fuse url. This series of fuse has many deserves this sort of as good in heat dissipation, large mechanical power, dependable in get in touch with, handy in efficiency and so on.
