CJX2-F series Large CapacityAC contactor is mainly used for AC 50Hz or 60Hz, with working voltage up to660V and working current up to 800A. It is used for long distance connection and breaking current. It is also suitable for frequent start and control of electric motor. It can be combined with auxiliary contact group, air delay head, mechanical interlock, and then form mechanical interlock contactor, star-delta starter, and suitable thermal overload relay. An electromagnetic starter is designed to protect from possibility of operating an overload circuit.
