ZFN16A-12 series indoor AC high-voltage load switch fuse combination electrical applianceDetailed product description：

The ZFN16A-12 series indoor AC high-voltage load switch fuse combination device meets the international and national standards of GB3807-90 "3-63KV AC high-voltage load switch" and IEC420 "AC high-voltage load switch fuse combination device" in terms of performance.
The ZFN16A-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 isolation fracture, low manual operation force, and can be equipped with two types of vacuum arc extinguishing chambers: ceramic tube or glass tube
