The CJX2-09 AC Magnetic Contactor is a fundamental component for industrial automation and motor control. Designed for making and breaking electrical circuits over long distances, this contactor is most commonly used for frequent starting and controlling of AC motors.
Rated for 9A (AC-3), the CJX2-09 is part of the world-standard CJX2 series, renowned for its compact footprint and high operational reliability. It features a robust electromagnetic system and high-conductivity silver-alloy contacts, ensuring stable performance even in high-frequency switching environments. Whether integrated into a simple pump starter or a complex automated production line, the CJX2-09 provides the precision and durability required for modern electrical engineering.

• High-Grade Silver Alloy Contacts: Features silver-cadmium oxide or silver-nickel contacts that provide superior conductivity and exceptional resistance to electric arc erosion and welding.

• Versatile Coil Voltage Options: While the standard unit operates at 220V AC, we provide a full range of coil voltages (24V, 36V, 48V, 110V, 380V) to match any control circuit requirement.

• Snap-On DIN Rail Installation: Optimized for 35mm standard DIN rail mounting, significantly reducing installation time in control panels. It also supports traditional screw-hole mounting for permanent fixtures.

• Modular Auxiliary Contacts: Equipped with a built-in auxiliary contact (1NO or 1NC). The top-facing mounting slots allow for the easy addition of F4 auxiliary contact blocks or pneumatic delay timers.

• Flame-Retardant Enclosure: The housing is made of high-strength, heat-resistant engineering plastic (UL94-V0 rated), ensuring safety and preventing deformation under high thermal stress.

1. Direct-On-Line (DOL) Starters: Used as the primary switching element for industrial water pumps, exhaust fans, and conveyor motors.

2. HVAC Systems: Controlling compressors and blower motors in centralized air conditioning units.

3. Automatic Transfer Switches (ATS): Integrated into power switching logic for backup generator systems.

4. Lighting Control: Handling high-power lighting banks in stadiums, factories, and commercial parking lots.

• Proven Durability: Our contactors are tested to withstand over 10 million mechanical operations, ensuring they outlast standard budget alternatives in heavy-duty cycles.

• Global Compatibility: The mounting dimensions and terminal labeling follow international standards, making them a perfect drop-in replacement for Schneider LC1-D09 series contactors.

• Precision Coil Windings: High-purity copper wire used in the electromagnetic coil prevents overheating and reduces the "humming" noise often associated with low-quality contactors.

• Strict Quality Control: Every unit undergoes a rigorous pull-in and release voltage test to ensure reliable switching even during minor voltage fluctuations.

Q: Can I use the CJX2-09 for a single-phase motor?
A: Yes. You can use a 3-phase contactor for a single-phase load by either using two of the three poles or wiring the poles in series to improve contact life.
Q: What is the difference between AC-1 and AC-3 ratings?
A: AC-3 refers to inductive loads like squirrel-cage motors (where the starting current is high). AC-1 refers to non-inductive or slightly inductive loads like heaters or incandescent lamps. The CJX2-09 is rated 9A for AC-3 and up to 20A for AC-1.
Q: Does it come with a surge suppressor?
A: Standard units do not, but we offer optional clip-on RC surge suppressors or varistor modules to protect sensitive PLC outputs from coil back-EMF.
