The high-voltage vacuum circuit breaker is the new generation VCB.It can be installed on distribution lines breaking short circuit current.It's used for overhead distribution lines interval switching,control and protection,as well as for monitoring the load current and zero sequence current.
The high-voltage vacuum circuit breaker is mainly made up of body,operating structure and accessories,the operating structure is generally the manual and electric spring mechanism.
This VCB has simple structure,high current breaking ability,safe operation and no risk of explosion.It's widely used in electrical power,metallurgy,machinery,chemical and other industries.
