FZRN25-12D Indoor High Voltage Air Pressure Type Breaker Vacuum Load Switch

Overview

FZN25-12 indoor high voltage vacuum load switch is a three- phase AC 50Hz, rated voltage 12kV indoor device, used with industrial and mining enterprise power distribution stations and substations and other occasions, as the protection and control of electrical facilities, used to divide load current, closed-loop current, 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 power distribution stations and substations and other occasions, for load control and short circuit protection. Equipped with a grounding switch that can withstand short-circuit currents. The operating mechanism can be manually closed electrically, which is convenient to realize the three remote control requirements of the power system.

FZN25-12, FZRN25-12 series load switches and combination electrical appliances are suitable for three-phase ring network or terminal power supply urban distribution stations and industrial power equipment, for load control and short circuit protection. Because the protective effect of combined electrical appliances on electrical equipment such as transformers is more reliable and economical than open circuits, it is especially suitable for ring networks, dual-radiation power supply units and box-type substations.
