 (1) The main purpose 
 CJ12 AC contactor is mainly used in AC 50Hz, rated working voltage up to 380V, rated operating current of 100A-600A power lines, electrical equipment for metallurgy, steel rolling enterprise, cranes, etc. for remote making and breaking circuit, and as frequent AC motor start, stop, reverse and reverse. 

 (2) structural characteristics of 
 AC contactor CJ12 system for the open type, its structure is bar frame layout of the electromagnetic system the right hand side, the main contact center, auxiliary contacts to the left, and equipped with a rotating stop file, the whole arrangement to facilitate the monitoring and maintenance. The magnetic system of the contactor by the "U"-type movement of core and coil, core movement with buffer device, thereby increasing the life of the product. CJ12Z for DC magnetic system. The main contacts of the contactor system as a single breakpoint rotating structure with a clay longitudinal seam interrupter cover, has a good extinction performance. Auxiliary contact to bridge pairs of breakpoints, the transparent shield; vulnerable parts of the whole contactor has easy disassembly and ease of maintenance repair and other features. 

 The main difference between the 3.CJ12A and B types of 

 Type A and B-type main difference between the interrupter principle, so the shape is not the same type A interrupter shield grille piece, longitudinal seam; the inside of the B-type interrupter cover rows of iron bars film. 
 Type A is the magnetic blow the interrupter principle, static contact lead after three to four spiral welded with the input terminals, magnetic splint in the static and dynamic contact on both sides of the longitudinal seam clay interrupter cover clamp live in order to prevent the interrupter cover off, both sides of the elastic wire interrupter cover fixed live. The interrupter principle is the arc by the magnetic traction pulled the cooling interrupter interrupter cover. 
 B-type contactor is the gate piece interrupter principle, the static contact lead is not spiral. Interrupter cover is also a clay material, but there are a lot of horizontal grille piece, relying on the lower edge of the grille piece gap arc interrupter. 
 The internal structure of the type A complex, the interrupter is better than B-type. Pay attention to the application.
