Frequently Asked Questions (FAQ)
What do the code designations "10", "01", and "11" mean for CJX2 contactors?
For contactors rated at 32A and below, "10" designates 3 normally open main contacts and 1 normally open auxiliary contact, while "01" designates 3 normally open main contacts and 1 normally closed auxiliary contact. For contactors rated at 40A and above, "11" designates 3 normally open main contacts, 1 normally open auxiliary contact, and 1 normally closed auxiliary contact.
What are the ambient air temperature limits for installing the CJX2 series AC contactor?
The ambient air temperature must be kept within the range of -5℃ to +40℃. Additionally, the average temperature over a 24-hour period should not exceed +35℃.
Is there an altitude limitation for the installation of these contactors?
Yes, the installation altitude for the CJX2 series AC contactors should not be higher than 2000 meters above sea level.
How does humidity affect the operation and installation of the contactor?
At the maximum temperature of +40℃, the relative humidity should not exceed 50%. However, higher relative humidity is permitted at lower temperatures (e.g., up to 90% at 20℃). Special measures must be implemented to manage occasional condensation caused by temperature fluctuations.
What is the allowed inclination angle for the installation surface?
The inclination between the vertical plane and the mounting surface of the CJX2 series AC contactor must not exceed ±5°.
What are the pollution level and installation category ratings for this product?
The CJX2 series AC contactor is rated for Pollution Level 3 and falls under Installation Category (Overvoltage Category) III.
