Air load break switch FK(R)N12BEL-12D

FKN12BEL-12D series air-blast load break switch and FKN12BEL-12D series air-blast load break switch-fuse combination apparatus are new series switchgear applies to three-phase electric distribution system of rated 12kV, acting as protecting and control apparatus for transformers, cable and overhead lines.
These series are especially applicable in rural, urban terminal substation and prefabricated substations, as well as ring network power supply.  FKN12BEL-12D can break and make load current and over-current. FKN12BEL-12D can break and make over-current, load current and short-cir cuit current (limited current fuse).
This product is featured with compact structure, aesthetic appearance, reliable interlock and high insulating level. In the spring storage operation  mechanism, ON/OFF speed is free from the influence of manpower. For the arc-extinguish, electric arc-extinguish inside the insulating cover, the free gas occurs at sparking do not cause descend of insulating level between phases and phase to earth. The insulation cover clapboard separates electrified  part thus boost protection grade of ring main unit. The copper-tungsten contact  and main contact brings along reliable conductivity and long life. This product has easy maintenance and operation as well as reliable performance. It is in compliance with IEC62271-105.
