Frequently Asked Questions (FAQ)
Can ZHC contactors be customized for specific applications?
Yes, all products can be customized for production according to the user's specific usage scenarios and requirements.
What do the auxiliary contact numbers 10, 01, and 11 mean?
"10" means three normally open main contacts and one normally open auxiliary contact (32A and below); "01" means three normally open main contacts and one normally closed auxiliary contact (32A and below); "11" means three normally open main contacts, one normally open auxiliary contact, and one normally closed auxiliary contact (40A and above).
What are the ambient air temperature and altitude limits for installation?
The ambient air temperature must be between -5℃ and +40℃ (with a 24-hour average not exceeding +35℃). The installation altitude should not exceed 2000 meters.
What are the relative humidity requirements for the operation environment?
At the maximum temperature of +40℃, the relative humidity should not exceed 50%. Higher relative humidity is permitted at lower temperatures (e.g., up to 90% at 20℃). Special precautions should be taken to prevent condensation.
What is the maximum allowed installation inclination for the contactor?
The inclination between the contactor's installation surface and the vertical plane must not exceed ±5° to ensure proper operation.
What is the rated insulation voltage of the ZHC contactor series?
All ZHC contactor models, from ZHC-09 up to ZHC-95, have a rated insulation voltage of 690V.
