Frequently Asked Questions
Can these contactors be customized for specific applications?
Yes, all products of the company can be customized for production according to the user's specific usage scenarios.
What does the auxiliary contact designation "11" mean for the ZHCt models?
The "11" designation means the contactor is equipped with three normally open main contacts, one normally open auxiliary contact, and one normally closed auxiliary contact.
What are the ambient temperature requirements for normal operation?
The ambient air temperature must remain between -5℃ and +40℃, and the average temperature over a 24-hour period should not exceed +35℃.
What is the maximum installation altitude and inclination allowed?
The contactors should be installed at an altitude no higher than 2000 meters, and the inclination between the installation surface and the vertical plane must not exceed ±5°.
How does humidity affect the working conditions of the contactors?
At a peak temperature of +40℃, the relative humidity should not exceed 50%. However, higher humidity levels (e.g., up to 90% at +20℃) are acceptable at lower temperatures, provided special measures are taken for occasional condensation.
