This collection fuse is appropriate for AC 50Hz, rated voltage to 600V, rated present to 125A. It is mainly utilized for defending the electrical circuit in opposition to overload and quick-circuits(gG/gL). Because of diverse melting tablets, it also could derive for rotecting the semiconductor gadget and other people total established installment from quick-circuit (aR/gR/gs/gtr) as well as the electric motor from limited-circuit (aM). The rated breaking capacity is to 100KA. They conform to countrywide common GB13539 and international
electrical committee regular IEC60269.
This sequence of fuse is made up of fuse url and fuse base. The variable cross-area fuse physique manufactured by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the fusion tube which is made by the higher power porcelain or epoxy glass fabric pipe, there is total of the high-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 connect with the finish plate and to form the cylindrical cap condition composition. Fuse foundation suppressed by the resin or plastic casing equipped with contacts and contains the fusion items, the connection made by riveting as the assistance of the appropriate measurement fuse human body components. This sequence of fuse has many deserves this kind of as small in dimensions, practical for set up, safe in usage, lovely in appearance and so on.
