Product Description


12kV high voltage Indoor Vacuum Circuit Breaker with power switchgear


ZN63(VS1)-12 Indoor High Voltage Vacuum Circuit Breaker is three-phace voltage 50Hz Power , 12kV Rate voltage power system indoor switch equipment . As grid Equipment and Electrical Equipment in Industrial and Mining Enterprises . Lend Itself to frequent Opration on Rate Voltage and Opening short Circuit Current .


The circuit breaker adopts an integrated design of operating mechanism and circuit breaker body , It can be used as a fixed installation unit or with a professional propulsion mechanism ,Role of component vehicle unit .


VS1-12 / M circuit breaker(with permanent magnet actuator) using vacuum arc extinguishing chamber, vacuum as arc extinguishing and insulation medium, arc extinguishing chamber has very high truth

VS1-12 VS1-12 Vacuum circuit breaker, voids, when the contact and static contacts are electrically divided under the action of the actuating mechanism, a vacuum arc will be generated between the contacts, and due to the special structure of the contact, an appropriate longitudinal magnetic field will be generated in the contact gap, which will cause the vacuum arc to remain diffusible and will spread evenly over the contact surface, maintaining a low arc voltage when the current is natural, The residual ion, electron and metal steam can be combined or assembled on the contact surface and shield over an order of magnitude of a microsecond, and the dielectric insulation of the interrupter break is quickly restored, resulting in the arc being extinguished and broken. As the vacuum breaker uses a magnetic field to control the vacuum arc, it has a strong and stable ability to break current.
