FZN23-12 High voltage vacuum load switchDetailed product description：

FZN23-12 (D)/630 indoor vacuum load switch and FZRN23-12 (D)/125 vacuum load switch fuse combination are suitable for high-voltage switchgear with three-phase AC 50Hz and 12kV. They are used for breaking load current and closing short-circuit protection. The combination can also break short-circuit current for short-circuit protection. They are the main components for controlling and protecting power equipment such as transformers, cables, and overhead lines.
