Frequently Asked Questions (FAQ)
Can the CJX2t series contactors be customized?
Yes, all products of the company can be customized for production according to the user's specific usage scenarios.
What are the ambient temperature requirements for installing these contactors?
The ambient air temperature should be within the range of -5℃ to +40℃. Additionally, the average temperature within a 24-hour period should not exceed +35℃.
What is the maximum altitude allowed for normal operation?
The installation altitude for the contactors should not be higher than 2000 meters above sea level.
How do the auxiliary contact codes "10", "01", and "11" differ for the CJX2t series?
"10" means 3 normally open main contacts and 1 normally open auxiliary contact (for 32A and below); "01" means 3 normally open main contacts and 1 normally closed auxiliary contact (for 32A and below); "11" means 3 normally open main contacts, 1 normally open auxiliary contact, and 1 normally closed auxiliary contact (for 40A and above).
What are the atmospheric humidity limits for the contactors?
At the highest temperature of +40℃, the relative humidity of the air must not exceed 50%. However, higher relative humidity is permitted at lower temperatures (e.g., up to 90% under 20℃). Special measures should be taken for occasional condensation caused by temperature changes.
What is the maximum allowed installation inclination?
The inclination angle between the installation surface of the contactor and the vertical plane should not exceed ±5°.
