FZRN25-12D/ FZN25-12D Indoor H.V. Vacuum Pressurised Air Load Break Switch

FZ(R)N25 vacuum load switch and combined electrical appliances, suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment, used for load control and short circuit protection, load switch on and off load, closed loop current, no-load transformer and cables recharging current. Combination appliances can break any current up to the rated short-circuit current. The linkage between the direct-acting isolation fracture and the vacuum interrupter is adopted. With manual and electric functions.

With the unique transmission structure design, the arc extinguishing chamber only bears high pressure at the moment of closing and breaking, so it is small in size and light in weight.

It can realize the one-time operation of the isolation fracture and the interrupter fracture.

Between the static contact and the conductive cylinder of the moving contact, there is a grounding valve interlocked with the grounding switch, which not only ensures safety but also facilitates maintenance.
