Introduction to the AC Contactor
ZHIMING brand of the CJX1 series AC contactor is suitable for circuits with AC 50Hz or 60Hz frequency and a rated operational voltage up to 1000V. Under the AC-3 utilization category, it is applicable for circuits with a rated voltage of 380V and a rated current up to 475A. It is mainly used for remote making and breaking of circuits, as well as for frequent starting and controlling of AC motors. When combined with an appropriate thermal overload relay, it can be assembled into an electromagnetic starter to provide overload protection for the circuit.
This product complies with the standards GB/T 14048.4 and IEC 60947-4-1.
