12KV 24kv Three Pole LBS Load Break Switch 11KV Indoor High Voltage Disconnector Switch Mechanism
Overview:
FZRN25-12D vacuum load switch and combination electric appliance, suitable for three-phase AC 50Hz ring network or terminal power supply and industrial power equipment, for load control and short circuit protection, load switch split load, closed loop current, no load transformer And cable charging current. The combination can break any current up to the rated short-circuit current. Direct-acting isolation fracture and vacuum arc linkage are adopted. With manual and electric functions.
FZRN25-12D's unique transmission structure design, the arc extinguishing chamber is only subjected to high pressure at the moment of closing and breaking, so it is small in size and light in weight.
The FZRN25-12D enables one-time operation of the isolation fracture and the interrupter of the arc chamber.
FZRN25-12D has a grounding valve interlocking with the grounding switch between the static contact and the moving contact conductive tube, which ensures safe and convenient maintenance.
