CJX1 series AC contactors are mainly used to make and break electric circuit at a long distance in circuit of AC50Hz or 60Hz, rated insulation voltage up to 690V and 1000V, rated operational current up to 400A under the utilization category AC-3 and rated operational voltage up to 380V. They are also suitable for frequent starting, stopping and reversing control of AC motor. They are used in combination with overload relay to compose a magnetic motor starter for protecting circuit where operational overload may happen.

The products conform to the standard of IEC60947-4-1, GB14048. 4 and GB14048. 5.
