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.
