one. Software
This series fuse is ideal for AC 50Hz, rated voltage to 600V, rated present to 125A. It is largely utilised for safeguarding the electrical circuit towards overload and brief-circuits(gG/gL). Due to the fact of different melting tablets, it also could derive for rotecting the semiconductor system and other individuals total established installment from short-circuit (aR/gR/gs/gtr) as effectively as the electric powered motor from short-circuit (aM). The rated breaking capability is to 100KA. They conform to nationwide normal GB13539 and international
electrical committee standard IEC60269.
two.CZPT Attribute
This collection of fuse is composed of fuse url and fuse base. The variable cross-area fuse human body manufactured by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the fusion tube which is made by the higher strength porcelain or epoxy glass cloth pipe, there is full of the high-purity quartz sand processed soon after chemistry to get the extinguishing of arc medium in the tube. The two sides of the fuse use the location welding to reliably link with the stop plate and to type the cylindrical cap form framework. Fuse base suppressed by the resin or plastic casing equipped with contacts and is made up of the fusion pieces, the connection created by riveting as the support of the suitable dimensions fuse entire body parts. This collection of fuse has a lot of deserves this sort of as modest in measurement, handy for set up, risk-free in use, stunning in physical appearance and so on.
