W Type Current-Limiting High Voltage Fuse for Motor Protection
Basic Info

Model No.:  WDF. O, WKF. O

Product Description Model NO.: WDF. O, WKF. O Type: Current Fuse Shape: Tubular Structure Fusing Device: Striker Foreign Model:Wdf.O: Department: Xrnm1 Rated Breaking Current(Ka):50: Diameter:51mm Specification: IES, BS HS Code: 8535100000 Breaking Capacity: High Usaga: High Voltage Electrical System Fusing Speed: Quick Standard: GB15166.2, IEC282-1, Bs Rated Voltage:3.6kv: Rated Current of The Fuse Links:50, 63, 80, 100, Trademark: SR Origin: China 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.
