FN12-12 Indoor High-Voltage Load Switch Fuse Combination Device
FN12-12 and FN12-12R combined apparatus are three-phase high-voltage switchgear with a rated voltage of 12KV and a rated frequency of 50Hz. They are used for breaking and closing load current, closed-loop current, no-load transformer and cable charging current, closing short circuit current, and load switches equipped with grounding switches. They can withstand short circuit current and are mainly used in urban power distribution stations and industrial electrical equipment with three-phase loop network or terminal power supply for negative control and short circuit protection.
