New Original CHINT CJX2-4011 AC220V Contactor Fast Shipping
2.Product Description
The CHINT CJX2-4011 is a 3pole AC contactor designed for reliable remote switching, frequent motor starting, and circuit control in industrial and commercial power systems. Rated for a main circuit voltage up to 690V AC and a control coil voltage of 220V AC (50/60Hz), it features a 40A rated operational current under the AC3 utilization category (standard for squirrelcage motor control). This model integrates 3 main normallyopen (NO) power contacts plus 1 auxiliary NO and 1 auxiliary normallyclosed (NC) contact, making it suitable for motor control circuits, power distribution panels, conveyors, pumps, fans, and general industrial automation. Built with highconductivity copper coils, silveralloy main contacts, and a robust electromagnetic mechanism, it ensures stable performance, low contact resistance, and long mechanical and electrical life.
Main Functions
- Main Circuit Control
- Switches 3phase AC circuits up to 690V, with a rated operational current of 40A (AC3 at 400V), enabling direct control of 3phase motors up to approximately 18.5kW.
- Provides reliable makeandbreak for resistive, inductive, and motor loads, supporting frequent starting and stopping operations.
- Auxiliary Contact Signaling
- Includes 1 NO and 1 NC auxiliary contact for interlocking, status indication, or control circuit feedback in automation systems.
- Auxiliary contacts support lowpower control signals, facilitating integration with PLCs, relays, and control panels.
- Electromagnetic Actuation
- Operates via a 220V AC control coil, generating stable electromagnetic force to close main and auxiliary contacts when energized.
- Features a springreturn mechanism for quick, positive contact opening when the coil is deenergized, preventing welding and ensuring safe disconnection.
- Motor Protection Compatibility
- Designed to pair with thermal overload relays to form complete electromagnetic starters, providing overcurrent and phasefailure protection for motors.
- Wide Application Flexibility
- Suitable for AC1 (resistive load), AC3 (squirrelcage motor starting/stopping), and AC4 (plugging/slowing of motors) utilization categories, adapting to diverse load types.
