Frequently Asked Questions (FAQ)
What are the standard ambient temperature limits for CJX1 AC contactors?
The ambient air temperature must be within the range of -5℃ to +40℃. Additionally, the average temperature over a 24-hour period should not exceed +35℃ to ensure normal operation.
What is the maximum installation altitude for these contactors?
The CJX1 series AC contactors are designed for installation in areas with an altitude not exceeding 2000 meters above sea level.
How does relative humidity affect the contactor's performance?
At a peak temperature of +40℃, relative humidity should not exceed 50%. However, higher humidity is acceptable at lower temperatures (e.g., up to 90% at +20℃). Precautionary steps should be taken to manage occasional condensation.
What are the coil holding and releasing voltage ranges?
The contactor coil is designed to reliably hold between 85% and 110% of its rated control power supply voltage. It will reliably release within 20% to 75% of the rated control power supply voltage.
What are the requirements for the installation angle?
The contactor should be installed on a surface where the inclination relative to the vertical plane does not exceed ±5°. The environment should also be free from significant vibration or shock.
