FN7 Air Load Break Switch

1. FN7 Type 10kv 11kv 12kv indoor air load break switch fuse unit pole mounted lbs

FN7-12 series indoor AC HV load switch is a gas-production HV load switch and fuse combination unit with arc quenching principle.It is applied in three-phase AC 50Hz power system with rated voltage 12kV for breaking the load current and making the short-circuit current.The fuse combination unit can break the short-circuit current and has the function of single-phase fuse three-phase tripping and breaking.It is the ideal selection for protecting the line, equipment and transformer. Its performance meets the requirements of national standards GB 3804-2004 High-voltage alternating-current switches for rated voltage above 3.6kV and less than 40.5kV and GB 16926-2009
