General description
This series of contactors use vacuum switch tubes as arc extinguishing components, which have the characteristics of no arc flash, long life, no noise, small size, safe and reliable. It can be widely used in the power network of AC 50/60 Hz and rated operating voltage of 1140 volts to connect and disconnect circuits, and form an electromagnetic starter with appropriate thermal relays or electronic protection devices and other related protection devices, especially suitable for forming Explosive electromagnetic starter and various power control screens. It is the most ideal circuit device for coal, petroleum, chemical industry, metallurgy, machinery, transportation and power industries.
