High voltage load switch FZN25-12RD

Overview FZRN25-12 vacuum load switch and combined electrical appliances, suitable for three-phase AC 50Hz loop network or terminal power supply and industrial electrical equipment, for load control and short-circuit protection. The load switch separates and closes the load, closed-loop current, no-load transformer and Cable charging current. The combined electrical appliance can break any current up to the rated short-circuit current. The direct-acting isolation fracture and the vacuum interrupter are used for linkage. With manual and electric functions. With a unique transmission structure design, the arc extinguishing chamber can only withstand high pressure at the moment of closing and opening, so it is small in size and light in weight. It can realize the one-time operation of isolation fracture and interruption of arc extinguishing chamber. Between the static contact and the conductive cylinder of the moving contact, there is a grounding valve interlocking with the grounding switch, which not only ensures safety but also facilitates maintenance.
