H. V HRC Fuse Types a/B for Transformer Protection

Applicatoins
    H.V HRC current-limiting fuses type A/B for transformer protection is mainly used in AC 50Hz, rated voltage 3.6-40.5KV, rated current up to 160A circuit for protecting transformers and power equipment from overload and short-circuit. It can also be used with load switch, vacuum contact.
    It conforms to IEC282-1, GB15166.2 and BS standard.
  
Design Features
    A/B type H.V HRC current-limiting fuses is bus-bar installation. The fuse link is fastened to the bus bar directly with bolts. It is small in volume, reliable inconnection. The striker parallels to the fuse element made from pure silver. They are sealed in the fuse tube filled with chemically treated high-purity quartz 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 immediately at the appearance 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 merits and high current-limiting ability, high breaking capacity, quick and punctual in action, reliable in performance.
