      PRODUCT
      ■ H.V.C current-liniting fuses type W for transformer protection

      Applications
      H.V. HRC current-limiting fuses type S is mainly used in AC50HZ,rated voltage 3.6-10kv,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 Features
      W 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.

      Selection for W type motor current-limiting fuse

      When started with full voltage,rated current=twice of loade d motor current;when started under other circumstances,rated current=1.5 times of loaded motor current.For directly started motor,fuses of proper rated curren should be selected according to the following formula;1.5 times of loaded motor current.For directly started motor,fuses of proper rated current should be selected according to the following formula:
      Iy=N·In·φ
      Iy--starting current 
      N--ratio fo starting current and loaded cruuent,usually N∽6
      In--loaded motor current
      φ--comprehensive coefficient,see the table below

      Refer to time-current characteristic diagram forselection of proper H.V.Fuse link,rated current of fuse link should be more than 1.3 times than loaded motor current.
