Indoor high-voltage load switch FS-N25-12D/T630-20-200/630A

The FSN25-12D/T630-20 indoor AC high-voltage vacuum load switch is an indoor device with a three-phase AC 50Hz and a rated voltage of 12kV. It is suitable for industrial and mining enterprises, distribution substations, and other occasions. As a protection and control device for electrical facilities, it is used for dividing and closing load currents, closed-loop currents, no-load transformers, and cable charging currents.
Install a grounding switch with the ability to close short-circuit current.
The operating mechanism can be manual or electric, making it easy to achieve the three remote control requirements of the power system.
FSRN25-12D/T200-31.5 Indoor AC High Voltage Vacuum Load Switch - The fuse combination electrical device is a three-phase AC 50Hz, rated voltage 12kV indoor device, suitable for industrial and mining enterprises, distribution substations, and other occasions, used for load control and short circuit protection.
Install a grounding switch with the ability to close short-circuit current.
