This standard specifies the general types, parameters, technical requirements, test methods and inspection rules for CJX series AC contactors. This standard applies to CJX series AC contactors. Contactors are mainly used in circuits with AC 50Hz (or 60Hz), rated operating voltage up to 660V, and rated operating current up to 170A when the rated operating voltage is 380V under the AC-3 usage category, for long-distance connecting and breaking of circuits. And it can be combined with appropriate thermal overload relay to form an electromagnetic starter to protect circuits where operating overload may occur.
