H. V current-limiting fuses type W is mainly used in AC50Hz, rated voltage 3.6~10KV, rated current up to 400A(3.6KV),224A(7.2KV) circuit for protection transformers and power equipments from overload and short-circuit. It can also be used with load switch, vacuum contact.
It conforms to IEC282-1, IEC644,BS and GB15166.2 standard.
W type H. V HRC current-limiting fuses has two installation:bus-bar installation snd insert installation.it is small in volume,reliable in connection the power striker parallels to the fuse element made from pure silver .they are sealed. in the fuse tube filled with chemically treated high -purity quarta sand.it is made from heat resistand.high duty ceramic or epoxy glass.when fault circuit happens the fuse link metlts.the high resistant metal wire paralleling to fuse link melts immediatedly at the appearamce of the arc.and the strikerjumps out to push the chained equipment contact.signaling the melting or automatically cutting the circuit.W type H.V HRC current limiting fuse has many merits as high current limiting ability .high breaking capacity.quick and punctual in action.reliable in performance
