Summary
        FZN25-12D/630-20 type AC high voltage vacuum load switch is an indoor device with three-phase AC 50Hz and rated voltage of 12kV, which is suitable for industrial and mining, enterprise, power distribution station, substation and other occasions. It is used as the protection and control of electrical facilities, for opening and closing load current, closed-loop current, air load transformer and cable charging current.
         Equipped with manual and motor operating mechanism, it is convenient to realize the three remote control requirements of power system.
        FZRN25-12D/T200-31.5 AC high voltage vacuum load switch fuse combination device is an indoor device with three-phase AC 50Hz and rated voltage of 12kV, which is suitable for industrial and mining, enterprise, power distribution substation and other occasions for load control and short-circuit protection. Equipped with grounding switch, it can withstand short-circuit current. The operating mechanism can be operated manually and electrically, which is convenient to realize the three remote control requirements of the power system.
         FZN25-12D and FZRN25-12D load switches and combined electrical appliances are suitable for load control and short circuit protection in urban distribution stations and industrial electrical equipment with three-phase ring network or terminal power supply. Because the protection function of the combined electrical equipment to the transformer and other electrical equipment is more reliable and economical than the circuit breaker, it is especially suitable for the ring network, double radiation power supply unit and box type substation.
