FZ(R)N16A-12 INDOOR AC HIGH-VOLTAGE VACUUM LOAD SWITCHES (FUSE COMBINATION)
Product Overview
FZRN16A-12 series indoor AC high-voltage load switch-fuse — GB3804 combination electrical appliances, with performance up to GB3804.IEC420 “3~63kV AC high-voltage load switch” and IEC420 “AC high-voltage load switch-fuse combination electrical equipment” international standards and national standards.
FZN16A-12 series indoor high voltage vacuum load switch 6~12kV 50Hz ， is suitable for 6~12kV three-phase AC 50Hz power grid, used for breaking load current and closing short -circuit current, especially suitable for oil-free, no maintenance and f requent operation requirements Place.
This product has the advantages of independent isolation， fracture, low manual operation force, and can be equipped with， ceramic tube or glass tube vacuum interrupter. It is an ideal product for oil-free high- voltage switches and equipment upgrades.
