VCNR-10kV(12kV) Handcart Vacuum Contactor with Fuse
This series of products is suitable for three-phase indoor medium-voltage switchgear operating at an AC frequency of 50-60Hz, with a rated operating voltage of 6kV(7.2kV) or 10kV(12kV) in the main circuit. Its functional combination is flexible, and the structure is compact and reliable, featuring multiple protection functions, a long service life, and the ability to operate frequently. It can be widely used to switch on and off circuits for AC motors, transformers, and other loads, as well as for reactive power compensation using capacitors. The contactor is available in fixed or trolley-mounted versions, with the trolley model compatible with KYN28A (GZS1) type switchgear of widths 550, 650, and 800mm, making it a suitable replacement for VSC/P contactors.
This series is suitable for three-phase indoor medium-voltage switchgear operating at an AC frequency of 50-60Hz, with a rated operating voltage of 6kV(7.2kV) or 10kV(12kV) in the main circuit.
The main circuit uses a sealed pole structure, offering good insulation, a long service life, and stable and reliable mechanisms that can operate frequently.
Combined with fuse quick-break protection, it forms a perfect F-C combination device.
