Frequently Asked Questions (FAQ)
QWhat is the maximum altitude limit for installing the CJX1 series AC contactor?
The installation altitude for the CJX1 series AC contactor should not exceed 2000 meters above sea level.
QWhat are the ambient temperature and humidity requirements for proper operation?
The ambient air temperature must be between -5℃ and +40℃ (with a 24-hour average of ≤ +35℃). Relative humidity should not exceed 50% at +40℃, though higher humidity (up to 90%) is allowed at lower temperatures like +20℃.
QWhat are the coil operating voltage ranges for holding and releasing?
The contactor coil reliably holds at 85% to 110% of the rated control power supply voltage (Us) and reliably releases within 20% to 75% of Us.
QWhat is the rated insulation voltage (Ui) for the auxiliary circuit?
The auxiliary circuit features a rated insulation voltage (Ui) of 660V and a conventional thermal current (Ith) of 10A.
QWhat are the installation orientation and environmental restrictions?
The contactor should be installed with an inclination of no more than ±5° relative to the vertical plane, in a location free from significant shaking, impact, or vibration.
