Frequently Asked Questions (FAQ)
Can these contactors be customized for specific scenarios?
Yes, all products of the company can be customized for production according to specific user usage scenarios.
What are the ambient temperature requirements for installation?
The ambient air temperature should be within the range of -5℃ to +40℃, and the average temperature must not exceed +35℃ within a 24-hour period.
What is the maximum altitude allowed for installation?
The contactors should be installed at an altitude of not higher than 2000 meters.
What does the "11" auxiliary contact suffix signify?
The "11" designation means the contactor features three normally open main contacts, one normally open auxiliary contact, and one normally closed auxiliary contact.
What are the installation inclination limits for these contactors?
The inclination between the installation surface and the vertical plane must not exceed +5° during setup.
How does relative humidity affect the operating conditions?
At the highest temperature of +40℃, relative humidity should not exceed 50%. However, higher relative humidity is permitted at lower temperatures (e.g., up to 90% at 20℃). Special measures should be implemented if condensation occurs due to temperature fluctuations.
