The CJX1 Series AC Contactor is a high-performance switching solution designed for making, breaking, and frequently starting AC motors. Operating in systems up to 690V and 50/60Hz, the CJX1-12/22 model is renowned for its mechanical longevity and electrical stability.

Built to international technical standards, this series is a direct equivalent to the world-standard 3TF series design. It features a sophisticated double-break contact system and a compact modular frame, making it the premier choice for industrial motor control centers (MCC), HVAC systems, and heavy-duty automation panels.

• Superior Contact Material: Utilizing high-grade silver-alloy contacts to ensure low contact resistance and maximum resistance against arc erosion and welding under heavy-duty AC-3 loads.

• Double-Break Contact Architecture: The twin-break design increases the arc-quenching efficiency, significantly extending the electrical lifespan of the contactor compared to single-break alternatives.

• Flexible Auxiliary Configuration: The CJX1-12/22 comes with built-in auxiliary contacts (2NO+2NC), allowing for complex interlocking and signaling without the need for additional add-on blocks.

• High Operational Frequency: Capable of up to 1,200 operations per hour (for AC-3), ensuring reliable performance in rapid-start industrial cycles.

• Global Standard Compliance: Manufactured and tested to meet IEC 60947-4-1 and EN 60947 standards, ensuring safety and performance across international markets.

1. Industrial Motor Control: Direct-on-line (DOL) starting and stopping of three-phase squirrel-cage motors.

2. Star-Delta Starters: Used in combination with timers and thermal overload relays for high-torque motor starting sequences.

3. HVAC Systems: Controlling large compressor motors and industrial ventilation fans in commercial buildings.

4. Heating and Lighting: Reliable switching of non-inductive or slightly inductive loads in resistive heating circuits.

• Drop-in Compatibility: Identical mounting dimensions and terminal layouts as the 3TF series allow for seamless replacement of aging components in existing panels.

• Easy Maintenance: The arc chute and contacts are easily accessible, allowing for rapid inspection and maintenance without specialized tools.

• Dust-Proof Protection: The enclosed contact design prevents the ingress of industrial dust, ensuring high-reliability switching in textile mills and woodworking facilities.

• Rugged Coil Construction: High-quality copper windings and a reinforced magnetic core provide stable pick-up and drop-out voltages, even during slight grid fluctuations.

Q: Can I use the CJX1-12/22 for single-phase applications?

A: Yes. While designed for three-phase systems, you can use the three poles in series or parallel to control high-amperage single-phase loads.

Q: Is it compatible with thermal overload relays?

A: Absolutely. The CJX1 series is designed to be directly coupled with standard thermal overload relays (like the 3UA or LR series) to provide comprehensive motor protection.

Q: What is the significance of the "22" in CJX1-12/22?

A: The "22" denotes the built-in auxiliary contact configuration: 2 Normally Open (NO) and 2 Normally Closed (NC) contacts.
