Frequently Asked Questions (FAQs)

1. What is the CJX2 Industrial AC Contactor?

The CJX2 is a heavy-duty electromechanical switch (magnetic contactor) primarily used in industrial automation. It uses an electromagnetic coil to close or open its contacts, allowing a low-voltage control circuit to safely switch a high-power load circuit.

2. What functions does it provide?

It is designed for making and breaking electrical circuits over long distances. Its primary function is the frequent starting, stopping, and controlling of 3-phase AC motors. Additionally, when combined with a thermal overload relay, it functions as an electromagnetic starter to protect circuits from overload damage.

3. What are the key parameters influencing selection?

When selecting a CJX2 contactor, you must consider: Rated Operational Current (Ie) based on your motor’s full-load amps (e.g., 9A to 95A for AC-3 loads); Coil Voltage (Us) to match your control circuit (e.g., 24V, 220V, 380V); and the Load Category (AC-1 for resistive loads like heaters, AC-3 for inductive loads like squirrel-cage motors).

4. What are the currently available options?

The CJX2 series offers a wide range of models from CJX2-09 to CJX2-95, covering AC-3 operational currents from 9A up to 95A. For the control coil, you can select voltages including 24V, 36V, 48V, 110V, 220/230V, and 380/400V in either 50Hz or 50/60Hz frequencies.

5. What standards does it meet and which markets is it designed for?

This contactor is designed for the global industrial market. It strictly complies with international electrical standards and holds major certifications including CCC, CE, TUV, and CB, ensuring high safety and reliability for both European and international power grids.

6. What are the installation precautions?

Before installation, verify that the coil voltage matches your control power supply to prevent coil burnout. The contactor supports standard 35mm / 75mm DIN rail mounting as well as screw mounting. Ensure that the fastening torque for the wiring terminals meets the specified requirements (e.g., 1.2 N·m for smaller models, up to 9 N·m for the 95A model) to prevent loose connections and overheating.
