VCNR-12 Handcart Vacuum Contactor with Fuse
This series of products is suitable for three-phase AC indoor high-voltage switchgear with AC 50-60Hz and main circuit rated operating voltages of 7.2kV and 12kV. Its function combination is flexible, its structure is compact and reliable, and it has multiple protection functions. It has a long service life and can be operated frequently. It can be widely used for breaking and closing AC motors, transformers and other load circuits, and can also be used for capacitor reactive power compensation. The contactor can be selected as fixed type or handcart type. The handcart type can be used with 550, 650 and 800mm wide KYN28A (GZS1) type center cabinets, and can be used to replace VSC/P contactors. The main circuit of the contactor adopts a solid-sealed pole structure with good insulation performance and long life. The mechanism has electromagnetic holding and permanent magnet structures. It is stable and reliable and can operate frequently. With the fuse quick-blow protection, it forms a perfect F-C combination electrical appliance.
