The FZRN 16A-12 series indoor AC high-voltage vacuum load switch fuse combination device meets the international and national standards of GB3804-90 "3-63kV AC high-voltage load switch" and EC420 "AC high-voltage load switch fuse combination device" in terms of performance.
The FZRN16A-12 series indoor high-voltage vacuum load switch is suitable for use in 6-10kV three-phase AC 50Hz power grids as a means of breaking load currents and closing short-circuit currents. It is particularly suitable for places that require oil-free, non maintenance, and frequent operation.
This product has the advantages of independent partition port, low manual operation force, and can be equipped with two types of vacuum arc extinguishing chambers, ceramic tube or glass tube. It is an ideal product for oil-free high-voltage switches and equipment updates.
