Compact size,lightweight, and easy-to-handle
 - Type VY vacuum circuit breakers are more compactly sized and lighter in weight.
 - Compact size of v vacuum circuit breaker makes it possible to reduce the cybicle size and to minimize its installation space. Light weight of a vacuum circuit breaker makes it easy to house and install in a cubicle.

 Facilitated maintenance/inspection
 - Service life of the vacuum interrupter contact is long, current conductive parts of the main circuit can be easily maintanined and checked,are replacement of then vaccum interrupter is rarely required. 

 Low noise
 - Operating noise if very low,Since current is interrupted within the vacuum interrupter, inerrupting noise is barely audible on then inerior. There is no fear of explosion and fire,since operation is entirely safe. 

 
 Further safety
 - Employing a dead front structure in which the operation mechansim is arranged on then front size while the main circuit conductive section is mounted at the rear, operating safety is assured.
 - Enclosed in a steel housing, the operating mechanism is protected from dust adn dirt. 

 Sophisticated external view 
 _ Adopting a one-piece insulation frame incorporating and individual U-shaped frame for three pases and using two sheets of insulation materials for separating then individual frames from eash others, high insulation characteristics are assured.
