Model NO.: WDF. O, WKF. O
Standard: GB15166.2, IEC282-1, Bs
Foreign Model:Wdf.O: Department: Xrnm1
Rated Voltage:3.6kv: Rated Current of The Fuse Links:50, 63, 80, 100,
Rated Breaking Current(Ka):50: Diameter:51mm
Trademark: SR
Specification: IES, BS
Origin: China
HS Code: 8535100000
Applications:H. V HRC current-limiting fuses type W motor protection is mainly used in AC 50Hz, 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 with load switch, vacuum contact.
It conforms to IEC282-1, IEC644, BS and GB15166.2.
When fault circuit happens, The fuse links melts, the high resistant metal wire paralleling to fuse link melts immediately at the appearance of the arc, and the sreiker jumps out to push the chained equipment contact, signaling the melting or automatically cutting the circuit. W type H. V HRC current-limiting fuse has many merits as high current limiting ablity, high breaking capacity, quick and punctual in action, reliable in performance.
