The RN3 high voltage current limiting fuse is used for overload and short circuit protection of power lines and transmission equipment.
Characteristics of RN3 high voltage current limiting fuse
1. The melt adopts a sheet-shaped variable cross-section multi-fracture structure to enhance the breaking ability. The breaking speed is increased, and the insulation can be established quickly after breaking. The ability to combat overvoltage shock is improved.
2. RN3 series high voltage current limiting fuse. In order to work with the FN5 load switch. Completed the basic functions of the instructions.
3. According to the test method in the national standard draft GBL5166.1-5—“current limiting fuseâ€, the short circuit capacity of 20-150 MVA can be interrupted, while the RN1 type can only break the short circuit capacity of 40-80 MVA. The RN3 can be used with FN5 to interrupt the overload current. Break the overload current.
4. The operating temperature of the fuse is lowered and the rated current of the fuse is improved.
