Overview

 

FZRN25-12/FZ(R)N25-12D type indoor high-voltage vacuum load switch and FZRN25-12D/T200-31.5 type indoor high-voltage vacuum load switch-fuse combination are the control of three-phase AC 50Hz.12kV power distribution system And protection device, the product is oil-free, non-toxic, non-flammable and explosive, widely used in industrial and mining enterprises and urban building power distribution stations and other places. The latter is more reliable in protecting electrical equipment such as transformers than circuit breakers, and is especially suitable for ring networks, dual auxiliary power supply units and box-type substations.

 

FZRN25-12D/T630-20 indoor high-voltage vacuum load switch (hereinafter referred to as load switch) is an indoor device with three-phase AC 50Hz and rated voltage 12k. It is suitable for industrial and mining enterprise power distribution stations and substations. Protection and control for splitting and closing load currents, closed loop currents, no-load transformers and cable charging currents. It has a grounding switch capable of making short-circuit currents. Its operating mechanism can be manual and electric, which is convenient to realize the three-remote control requirements of the power system.

 

FZRN25-12D/T200-31.5 indoor high-voltage vacuum load switch-fuse combination (hereinafter referred to as combination) is an indoor device with three-phase AC 50Hz and rated voltage of 12kV, suitable for industrial and mining enterprise power distribution stations and substations and other occasions , for load control and short circuit protection. It also has a grounding switch capable of closing short-circuit current. Its operating mechanism can be manual and electric, which is convenient to realize the three-remote control requirements of the power system.
