Description:
FN12-12 Series AC HV Load Switch is a kind of three phase high voltage switch apparatus, suitable for 12kV 
rated voltage, 50Hz rated frequency alternative current, It is mainly used in downtown power distribution station 
and industrial electric equipment of three phase ring main unit electricity circle or terminal power supply, for 
breaking and closing short circuit current. This switch shall be fitted with special operative mechanism. (manual 
or electrical operation).
Suitable for control and protection of power equipment such as transformers, cables, overhead lines, etc. in 10kV, 50Hz three-phase distribution systems. Widely used in terminal substations and box substations of urban and rural power grids, and suitable for control and protection of ring networks and dual radiation power supply units. FZN25-12 (D)/T630-20 Indoor High Voltage AC Vacuum Load Switch FZRN25-12 (D)/T200-31.5 Indoor High Voltage AC Vacuum Load Switch Fuse Combination Electrical Appliances
Product Introduction: FZN25 and FZRN25 vacuum load switches and combination appliances are suitable for load control and short circuit protection in three-phase AC 50Hz ring networks or terminal power supply and industrial electrical equipment. The load switch separates and closes loads, closed-loop currents, no-load transformers, and cable charging currents. The combination electrical appliance can be disconnected to any current up to the rated short-circuit current. Adopting direct action isolation fracture and vacuum arc chamber linkage. Equipped with manual and electric functions. The unique transmission structure design of FZN25 and FZRN25 allows the arc extinguishing chamber to withstand high voltage only at the moment of closing and opening, resulting in small volume and light weight.
