Vacuum Load break switch Indoor H.V. FZN25-12RD

Model: 

FZN25-12RD/T630-20

Overview:

FZN25 and FZRN25 vacuum load switches and combined electrical appliances are suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment for load control and short-circuit protection. Load switches open and close loads, closed-loop current, and no-load transformers. and cable charging current. The combined electrical appliance can break any current up to the rated short current, and adopts direct-acting isolation break and linkage with the vacuum arc extinguishing chamber. Available in manual and electric functions.

FZN25 and FZRN25 vacuum load switches and combined electrical appliances can realize one-time operation of isolation fracture and arc extinguishing chamber fracture.

FZN25 and FZRN25 vacuum load switches and combined electrical appliances have high temperature resistance, strong insulation, and flame-retardant transparent glass covers between the static contacts and the moving conductive cylinder, which effectively ensures the safe operation of the equipment and personal safety. The load switch and grounding switch are equipped with reliable mechanical interlocking, which not only ensures safety but also facilitates maintenance.
