2. Selection Guidelines

Select the appropriate model based on load type (resistive/inductive), rated current, control voltage, and operating frequency.

2. Installation Notes

Inspect product appearance before installation to ensure no damage

Tighten terminal screws securely to avoid overheating from loose connections

When used with thermal relays, maintain a gap ≥ 5mm for heat dissipation

3. Maintenance Suggestions

Regularly check contact wear; replace contacts if wear exceeds 1mm

Clean the coil core surface to remove dust and oil for reliable attraction

Inspect and retighten loose wiring terminals

VII. Key Tips

1. CJX2-25 is a standard contactor for general industrial control. For high-frequency operation (>600 operations/hour), the CJX2S series (Pioneer series) is recommended.
2. Coil voltage must match the control circuit voltage to prevent coil burnout.
3. When replacing contactors of other brands, verify mounting dimensions and wiring methods to ensure compatibility.
