Determine whether the AC contactor can cut off the short circuit current?
Since the contact system is linked with the moving core, the movable iron core drives the three action contacts at the same time, the main contact closes, and the main Contact mechanical connection of the auxiliary normally closed contact open
When the coil is energized, the static core produces electromagnetic attraction, and the moving core is sucked
arc extinguishing device, the general capacity of the larger AC contactor are equipped with arc extinguishing device, in order to quickly cut off the arc, from burning the main contact;
insulation shell and accessories, all kinds of springs, transmission, short circuit, terminal and so on
