500V~120KA fuse/dc power cord with fuse

Application:

              This series fuse is suitable for AC 50Hz, rated voltage to 1000V, rated current to 1250A. It is

mainly used for protecting the electrical circuit against overload and short-circuit s(gG/gL) . Because

of different melting tablets, it also may derive for protecti ng the semiconductor device and others

complete set installment from short-circuit (aR/gR/gs/ gtr) as well as the electric motor from short

-circuit (aM). The rated breaking capacity is to 120KA. They conform to national standard GB13539

and international electrical committee standard IEC60269.

Construction Feature:

           This series of fuse consists of fuse link, fuse base and carrier fuse. The variable cross-section

fuse body made by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is made by the high strength porcelain or epoxy glass cloth pipe, the re is full of the high-purity quartz sand processed 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 end plate(or

junction panel) and to form the square knife shape contact structure. The fuse may have fuse indicator

or striker, when the fuse element fusing it can demonstrate fusing (indicator) or transforms each

kind of signal as well as automatic transfer circuit (striker). The fuse base consists of high temperature resistance resin plate(or high intensity porcelain plate) and wedge-shaped static contact to form open-type structure and it can be used as the supporting device of the appropriate size of the fuse link. This series of fuse has many merits such as good in heat dissipation, high mechanical str engt h,reliable in contact, convenient in performance and so on.
