HV Current Limiting Fuse Type A/B
A/B type High voltage current-limiting fuses has bus-bar installation .The fuse link is fastened to the bus-bar directly with bolts. it is small in volume. reliable in connection . The power striker parallels to fuse element made from pure silver . They are sealed ,in the fuse tube filled with chemically treated high-pu rity qua rtz sand. the fuse tube is made from heat resistant, high duty ceramic or epoxy glass. When fault circuit happens the fuse link melts, the high-resistant metal wire paralleling to fuse links melts immediatedly at the appearamce of the arc, and the striker jumps out to push the chained equipment contact, signaling the melting or automatically cutting the circuit , A/B type H.V. HRC current-limiting fuses has many merts as high current-limiting ability, high breaking capacity, quick and punctual in action, reliable in performance.
