Structural features
✦
The contact system of the contactor is direct-acting with double breakpoints, For CJ20-40A and above, the auxiliary contacts are installed on both sides of the main contact as independent components, which are electrically separated;
✦
CJ20-10-25A products may be installed by screws or by 35mm standard card track.
✦
CJ20-10-16A products have double breakpoints to simply break the arc extinguishing chamber, and the rest adopt the plastic grid are extinguishing chamber, which has the advantages of high breaking capacity and high reliability;
✦
C120-63~630 power saving products have the DC general power saving module, which not only can derive silencing energy saving products or DC operated products, but also do not occupy auxiliary contacts, thus greatly improving the reliability and life of products.
