INDOOR HIGH VOLTAGE VACUUM
LOAD BREAK SWITCH

Overview
FZN25-12 indoor high-voltage vacuum load break switch is an indoor device with three-phase AC 50Hz and rated voltage of 12kV. It is used with
industrial and mining enterprise power distribution stations and substations as protection and control of electrical facilities. It is used to divide and load
current, Closed-loop current, no-load transformer and cable charging current.
FZRN25-12 indoor high-voltage vacuum load switch fuse combination appliance is an indoor device with three-phase AC 50Hz and rated voltage of
12kV. It is suitable for industrial and mining enterprise power distribution stations and substations, etc. for load control and short circuit protection. The
equipped grounding switch can withstand short circuit current. The operating mechanism can be turned on manually to facilitate the realization of the
three remote control requirements of the power system.
FZN25-12, FZRN25-12 series load switches and combination appliances are suitable for urban power distribution stations and industrial power
equipment powered by three-phase ring network or terminal, for load control and short circuit protection. Because the protection effect of combined
appliances on transformers and other electrical equipment is more reliable and more economical than circuit breaking, it is especially suitable for ring
networks, dual-radiation power supply units and box-type substations.
