This sequence fuse is suited for AC 50Hz, rated voltage to 600V, rated existing to 125A. It is mostly employed for protecting the electrical circuit from overload and short-circuits(gG/gL). Simply because of diverse melting tablets, it also may possibly derive for rotecting the semiconductor system and other folks full established installment from limited-circuit (aR/gR/gs/gtr) as well as the electrical motor from brief-circuit (aM). The rated breaking ability is to 100KA. They conform to countrywide normal GB13539 and international
electrical committee standard IEC60269.
This series of fuse consists of fuse hyperlink and fuse foundation. The variable cross-section fuse human body manufactured by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the fusion tube which is produced by the high strength porcelain or epoxy glass cloth pipe, there is complete of the substantial-purity quartz sand processed soon after chemistry to consider the extinguishing of arc medium in the tube. The two sides of the fuse use the place welding to reliably join with the conclude plate and to form the cylindrical cap condition construction. Fuse foundation suppressed by the resin or plastic casing fitted with contacts and is made up of the fusion pieces, the link created by riveting as the assistance of the acceptable size fuse body components. This collection of fuse has several deserves this sort of as little in measurement, practical for installation, secure in use, beautiful in look and so on.
