Get ready to experience the power of VACYC permanent magnet AC M.V. vacuum contactor and VACFC series AC M.V. vacuum contactor-fuse combination apparatus (F-C)! These three-phase AC indoor middle voltage switch devices are perfect for AC 50-60Hz and have a rated working voltage of 7.2kV and 12kV. With their flexible function combination, compact and reliable structure, multiple protection functions, long service life, and frequent operation capabilities, these devices are the ultimate solution for opening and closing load circuits such as AC motors and transformers. Plus, they can also be used for capacitor reactive power compensation.
The VACFC series combination apparatus features a modular combination structure that can be used by a single contactor or combined into F-C. It can be fixed or drawout moving type, and the drawout type can be used with KYN28A(GZS1) intermediate cabinet with a width of 650mm or 800mm. It's the perfect replacement for VSC/P contactor.The VACFC contactor can be used alone or with other electrical apparatus. And with our 12kv Efficient High Voltage Vacuum Contactor-Fuse Combination Switch for Switchgear, you'll get the ultimate performance and reliability. So, what are you waiting for? Experience the power of VACYC and VACFC today!
