ApplicationsH.V. current-limiting fuses type A/B is mainly used in AC50HZ,rated voltage 3.6-40.5kv,rated current up to 200A circuit for protection transformers and power equipments from overload and short-circuit.It can also be used with load switch,vacuum contactor.It conforms to IEC282-1,GB15166.2 and DIN standard. Design FeaturesA/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 in connection,The striker parallels to the fuse element made of 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 cermic or epoxy glass.When fault circuit happens,the fuse link melts,the high-resistant metal wire paralleling to fuse linsk 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-liming ability,high breaking capacity,quick and punctual in action,reliable in performance
