Structural features

Contact system of AC/DC contactor for the arrangement of direct-acting and double-break, auxiliary contact of CJ20-40A and more as separate component installed in the both sides of the main contact, is separation in the electrical.

CJ20-10~25A AC/DC contactors can be installed with screws or 35mm standard card rails.

CJ20-10~16A AC/DC contactors use a double breakpoint simple opening arc chamber, and the rest use multi-longitudinal seam arcing cover or arcing cover enclosures, with high breaking capacity, high reliability.

CJ20-63~630 energy-saving AC/DC contactors have DC general power-saving module, not only can derive muffler energy-saving products or DC operation products, and do not take up auxiliary contacts, thus greatly improving product reliability and life.
