Description

FZN25/FZRN25 type vacuum load break switch and composite apparatus, suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment

Product 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.

Operating Methods

FZRN25 special transmission structure design, arc extinguish chamber only withstand voltage in the moment of closing and breaking, small size, low price.

◆It is suitable for three-phase AC 50 / 60Hz interruption power supply and industrial electrical equipment

◆For load control and short circuit protection

◆Load switch breaking load, closed-loop current, no-load transformer and cable charging current

◆The current of the combined apparatus is up to the rated short-circuit current

◆It adopts direct acting isolation fracture and vacuum arc linkage, with manual and electric functions Feature:

◆Unique transmission structure design, small volume and light weight,

◆The interrupter only bears high voltage at the moment of making and breaking.

◆It can realize the one-time operation of isolating fracture and interrupter end fracture

◆There is a grounding valve linked with the grounding switch between the static contact and the moving contact conducting cylinder

◆It is safe and convenient to inspect
