FN7-10 / 400A 630A FN7-10R / 400A 630A FN7-10D / 400A 630A FN7-10DR / 400A 630A FN7-10RA / 400A 630A FN7-10DXLRA / 400A 630A FN7-10DXLRAF / 400A 630A FN7-10 is a high-voltage load switch kinds of new inner gas-type indoor high voltage load switch for AC 50Hz, rated voltage of 12kV three-phase AC power system, as the breaking load current and closing short-circuit current. FN7-10 high voltage switches through a long-term test operational assessment, performance to IEC420 "AC high voltage load switch - fuse combinations" (1990 Edition) and GB3840 "3-63kV AC high voltage load switch" standards, compared with similar foreign products, technical parameters have reached the international level, having small size, light weight, can be used to ring counter and box-type substation, widely used in 12kV power distribution line, and effectively avoid missing running the equipment. Development of high voltage switches FN7-10 success to fill the gap, enabling switches, isolation and grounding three functions. FN7-10 high voltage switches can be equipped with CS6 type and disc-type manual operating mechanism or have side-mounted integrated mechanism to operate. The Company's solemn commitment, if customers are not satisfied, we will serve in the end. We have confidence in our products, quality bags with one year (including use, return, replacement) manufactured products are used export waterproof wooden box, the box with a perfect factory descriptions and product information.
