The BV12 Indoor Medium-voltage Solid-sealed Vacuum Circuit Breaker is an indoor switching device used in 12kV power systems, serving as protection and control equipment for power grids, industrial and mining enterprises, etc. Due to its outstanding advantages, it is particularly suitable for locations requiring frequent operation at rated working current or repeated interruption of short-circuit currents.

The circuit breaker adopts an integrated design of the operating mechanism and breaker body. It can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a withdrawable (handcart) unit. The fixed-type breaker can also be fitted with corresponding mechanical interlocks to meet the requirements of fixed switchgears such as XGN2, GG1A, GGX, etc.
