FZN25/FZRN25 type vacuum load switch

Description:
        FZN25/FZRN25 type vacuum load switch and composite apparatus, suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment. for load control and short circuit protection use, load switch open and close the closed-loop current, no-load transformer and cable charging current, composite apparatus can break any current till rated short circuit current. Adopt the straight move or isolating fracture and vacuum interrupter linkage. With the function of manual and electric operation.ZN25, FZRN25 special transmission structure design, arc extinguish chamber only withstand voltage in the moment of closing and breaking, small size, low price.ZN25, FZRN25 can realize isolation fracture and arc extinguish chamber fracture disposable operating FZN25, FZRN25 has a grounding switch mutual linkage grounding valve between the static contact and movable conductive cylinder, ensures safety and convenient maintenance.
