*Product   Description 




*Application 
H.V HRC  current - limiting fuses type W motor protection is mainly used in AC 5OHZ, rated voltage 3.6 - *0kV, rated current up to **0A ( 3.6kV ), **4A ( 7.2kV ) circuit for protecting motor and power equipment form overload and short - circuit. It can also be used withload switch, vacuum contact. It conforms to IEC**2 - 1, IEC**4, BS and GB****6.2.



*Design Features

W type H.V HRC current - limiting fuses has two installation: bus - bar installation and insert installation. It is small in volume, reliable inconnection 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 quartzsand. The fuse is made  from heat resistant,high duty ceramic or epoxy glass. When fault circuit happens the fuse link melts ,the high - resistant metal wire paralleing to fuse link melts immediatedly at the apperance of the arc, and the striker jumps out to push the chained equipment contact, signaling the melting or automatically cutting the circuit. W type H.V HRC current - limiting fuses has many merits and high current - limiting ablity, high breaking capacity, quick and punctual in action,reliable in performance.
