Product Description
FZRN25-12D indoor AC high-voltage vacuum load switch-fuse combination Units is an indoor device with three-phase AC 50Hz and rated voltage of 12kV. It is applicable to industrial and mining enterprise power distribution stations and substations for load control and short circuit protection. The grounding switch with the ability to close the short circuit current is equipped. The operating mechanism can be operated manually and electrically, which is convenient to realize the three remote control requirements of the power system.
