Basic Info

Model No.:  XRNMI

Product Description Model NO.: XRNMI Type: Fuse Shape: Circular Cylinder Material: Porcelain Length: 254/403/600mm Diameter: 51/76mm Trademark: SR Origin: China Breaking Capacity: High Voltage Circuit Breakers Usaga: High Voltage Standard: IEC Color: White,Brown Rated Current: 25-224A Rated Voltage: 7.2kv Specification: ISO9001 HS Code: 8535100000 Applications

H. V current-limiting fuses type W is mainly used in AC50Hz, rated voltage 3.6~10KV, rated current up to 400A(3.6KV),224A(7.2KV) circuit for protection transformers and power equipments 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 standard.

Design Features

W type H. V HRC current-limiting fuses has two installation:bus-bar installation snd insert installation.it is small in volume,reliable in connection 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 quarta sand.it is made from heat resistand.high duty ceramic or epoxy glass.when fault circuit happens the Fuse Link metlts.the high resistant metal wire paralleling to fuse link melts immediatedly at the appearamce of the arc.and the strikerjumps 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 ability .high breaking capacity.quick and punctual in action.reliable in performance


Key Specifications/Special Features:
1.motor protection
2.High breaking capability
3.High voltage current limiting fuse
4.Suitable for electrical power system of AC 50Hz, rated voltage 10kV and below, rated current up to 400A(3.6KV),224A(7.2KV) circuit for protecting motor and other power equipment from overload and short-circuit.
5.High-pressured fuse conforms to the national GB15166.2 standard and the international electrical committee IEC 60282 standard as well as German DIN standard and British BS standard.
