*Applications

H.V HRC curent-limiting fuses type W motor protection is mainly used in AC50Hz, rated voltage 3.6-10kV, rated current up to 400A(3.6kV), 224A(7.2kV) circuit for protecting motor and power equipment from overload and short-circuit. It can also be used withload switch, vacuum contact. It conforms to IEC282-1,IEC644,BS and GB15166.2.

*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 filled with chemically treated high-purity quartz sand. 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 paralleling to fuse link melts immediately at the appearance of the arc, and the striker jumps out to push the chained equipment sontact, signaling the melting or autimatically cutting the circuit. W type H.V HRC current-limiting fus ehas many merits as high current-limiting ability, high breaking capacity, quick and punctual in action, reliable in performance.
