Product Description

Product Description

FZN25-12 indoor high voltage vacuum load switch is a three-phase Ac 50Hz, rated voltage 12kV indoordevice, used with industrial and mining enterprise power distribution stations and substations and otheioccasions, as the protection and control of electrical facilities, used to divide load current, closed-loopcurrent,no-load transformer and cable charging current.
FZRN25-12 indoor high voltage vacuum load switch fuse combination electrical appliance is a three-phase AC 50Hz, rated voltage 12kV indoor device, suitable for industrial and mining enterprise powerdistribution stations and substations and other occasions, for load control and short circuit protectionEquipped with a grounding switch that can withstand short-circuit currents. The operating mechanismcan be manually closed electrically, which is convenient to realize the three remote control reguirementsof the power system.
FZN25-12, FZRN25-12 series load switches and combination electrical appliances are suitable forthree-phase ring network or terminal power supply urban distribution stations and industrial powerequipment, for load control and short circuit protection. Because the protective effect of combinedelectrical appliances on electrical equipment such as transformers is more reliable and economical thanopen circuits, it is especially suitable for ring, networks, dual-radiation power supply units and box-typesubstations.
