Product Overview

VBT series indoor AC high-voltage vacuum circuit breakers (hereinafter referred to as vacuum circuit breakers) are suitable for protection and control of electrical appliances in three-phase power systems with a rated voltage of 50Hz to 12kV and a rated current of 630-4000A.

The circuit breakers with high reliability, easy operation, and simple maintenance can be used for central and fixed switchgear, as well as oil-free transformation. Due to special advantages, the vacuum circuit breakers are particularly suitable for frequent operations under rated current or places where multiple interruptions of short-circuit current are required.

It can be widely used for infrastructure construction in power plants, power grids, metallurgy, petrochemical cities, such as airports, buildings, subways, etc.
