This series of contactors, manufactured by Yueqing Liyond Electric Co., Ltd., utilizes vacuum switch tubes as arc extinguishing components. These contactors boast features such as arc flash-free operation, long lifespan, noiseless operation, compact size, and high safety and reliability. They are designed for use in AC power networks with a frequency of 50/60 Hz and a rated operating voltage of 1140 volts. These contactors are ideal for connecting and disconnecting circuits, forming electromagnetic starters when paired with suitable thermal relays or electronic protection devices, and integrating with related protection devices. They are particularly well-suited for creating explosive electromagnetic starters and various power control panels. These contactors are highly recommended for industries such as coal, petroleum, chemical, metallurgy, machinery, transportation, and power.
