•Overview
FZN25-12/FZ(R)N25-12D Indoor High Voltage Vacuum Load Switch and FZRN25-12D/T200-31.5 Indoor High Voltage Vacuum Load Switch-Fuse Combination Appliance is a control and protection device for three-phase AC 50Hz, 12kV power distribution system, the product is oil-free, non-toxic, non-fire and explosion hazard, widely used in industrial and mining enterprises and urban building distribution stations and other places. The latter is more reliable than circuit breakers for the protection of electrical equipment such as transformers, and is particularly suitable for ring networks, dual auxiliary power supply units and box-type substations.
FZN25-12D/630-20 indoor high-voltage vacuum load switch (hereinafter referred to as load switch) is a three-phase AC 50Hz, rated voltage 12kV indoor device, suitable for industrial and mining enterprise power distribution and substation and other places, as the protection and control of electrical facilities, for the distribution of load current, closed-loop current, no-load transformer and cable charging current. It has a grounding switch that has the ability to close short-circuit currents. Its operating mechanism can be manual and electric, which is convenient to realize the requirements of three remote control of the power system.
FZRN25-12D/200-31.5 Indoor High Voltage Vacuum Load Switch-Fuse Combined Appliance (hereinafter referred to as Combined Appliance) is an indoor device with three-phase AC 50Hz and rated voltage of 12kV, which is suitable for power distribution stations and substations of industrial and mining enterprises for load control and short-circuit protection. It also has a grounding switch with the ability to close short-circuit currents. Its operating mechanism can be manual and electric, which is convenient to realize the requirements of three remote control of the power system.
