About UsProduct DescriptionProduct name: Introduction of
VS-12 series indoor high voltage vacuum circuit breakerModel VS1-12
indoor high voltage vacuum circuit breaker is the indoor switchgear
of a three-phase AC power system with ratedthe voltage of
50Hz and 12kV, which is used as the protection and control unit of
power grid equipment and power equipment ofindustrial and mining
enterprises.Suitable for frequent operation at rated operating
current, or multiple break short circuit current.The circuit
breaker adopts the integrated design of the operating mechanism and
circuit breaker body, which can be used as a fixed installation
unit or equipped with a special propulsion mechanism to form a hand
car unit.Detailed PhotosProduct ParametersItemUnitsParametersRated
