CJX21210 is a threepole AC contactor designed for motor control, with a 380V coil and normally open (NO) contacts. It is capable of switching up to 660V AC and handling up to 20A. This device belongs to the CJX2 family and is suitable for use in industrial control panels and motor starting circuits. Key benefits Reliable motor switching: enables safe, remote control of threephase motors in industrial settings. Safe default state: normally open contacts provide an OFF state when the coil is not energized, improving safety in control circuits. Simple integration: compact, straightforward mounting in standard control panels and switchgear. Versatile voltage range: supports coil operation at 380V AC and switching up to 660V AC, with a 20A load rating. Durable and robust: designed for repeated operation in demanding environments typical of industrial applications. Key attributes Model: CJX21210 Type: AC contactor, 3P (threepole), normally open (NO) Coil voltage: 380V AC Rated switching voltage: up to 660V AC Current rating: 20A Poles: 3 Intended use: motor control and general purpose AC switching in industrial controls Brand/series reference: CJX21210 (CJX2 series contactor) Functional capabilities Threepole configuration provides balanced control for threephase power systems. NO contacts default to open, enabling safe circuit behavior when power is removed. Compatible with standard control circuits that use a 380V AC coil and require handling up to 660V AC switching and 20A loads. Compatibility and suitability Suitable for use in equipment and control panels that require a 380V AC coil and a threepole NO contactor. Appropriate for motor starting and stopping tasks in manufacturing equipment, conveyors, ventilation systems, and other threephase loads. Works with control logic and PLCbased or manual control schemes seeking reliable remote switching of motors. Typical use cases Start/stop control for a threephase motor on a packaging line or conveyor system, controlled by a PLC or switch. Remote switching of fans or pumps in an industrial HVAC or process cooling system. Interlocking or gating of multiple machines in a production cell where threephase loads must be safely isolated when the control signal is inactive. Product usage notes Ensure the control circuit voltage is compatible with a 380V AC coil. Confirm that the load current does not exceed the 20A rating for safe operation. Observe proper wiring practices for threepole devices and integrate with appropriate protective devices as required by the application. Overall, the CJX21210 threepole NO AC contactor provides a clear, reliable solution for controlling threephase motors and other AC loads in industrial environments, with specifications that match the stated 380V coil, 660V switching capability, and 20A current rating.
