Characteristics
 
(In the mid 1980s, the successful development of VCB for the first time in Korea in cooperation with TOSHIBA of Japan)


Excellent  Insulation  Characteristics
  It guarantees excellent insulation by using U-type insulation on each phase.

Low Noise
  Operation noise is very low. When electric current is broke, the noise from
the machine is hardly audible. There is no fear of explosion and fire, since operation is entirely safe.

Further Safely
  It is almost unnecessary to change the vacuum breaker because it endures a long life, and the main conductor part can be easily maintained and inspected.

Safety Facility
  Since the controlling part is in the front while the conductor part of the main circuit is installed in the rear, it is very safe. The steel surface protecting the controlling part and major parts prevents dust and pollution.

Compact size, Light-weight, and Easy-to-handle
  Vacuum circuit breakers are more compactly sized and lighter in weight. Besides, it requires minimized space for installation because of the decrease in divisions. The compact size and light-weight enable the easy movement and installation inside the divisions.
