Product Description

The VS1-12 indoor high-voltage vacuum circuit breaker is a three-phase AC 50Hz, 24kV rated voltage indoor switchgear for power systems. It serves as a protection and control unit for power grid equipment and industrial and mining power equipment. It is suitable for applications requiring frequent operation at rated operating current or repeated short-circuit interruption.

The circuit breaker features an integrated operating mechanism and circuit breaker body, allowing it to be used as a fixed-mount unit or equipped with a dedicated propulsion mechanism to function as a trolley unit.
