Frequently Asked Questions (FAQ)
Q1: What is the meaning of auxiliary contact codes 10, 01, and 11?
A1: For contactors 32A and below, "10" indicates three normally open main contacts and one normally open auxiliary contact; "01" indicates three normally open main contacts and one normally closed auxiliary contact. For contactors 40A and above, "11" indicates three normally open main contacts, one normally open auxiliary contact, and one normally closed auxiliary contact.
Q2: What are the normal ambient air temperature limits for CJX2 contactors?
A2: The ambient air temperature should be within the range of -5℃ to +40℃, and the average temperature over a 24-hour period must not exceed +35℃.
Q3: What is the maximum installation altitude and inclination allowed?
A3: The installation altitude must not be higher than 2000 meters. The inclination angle between the installation surface and the vertical plane must not exceed ±5°.
Q4: How do atmospheric conditions and humidity affect installation?
A4: At the maximum temperature of +40℃, relative humidity should not exceed 50%. Higher relative humidity, up to 90%, is acceptable at lower temperatures (such as under 20℃). Special measures must be taken to handle occasional condensation caused by temperature changes.
Q5: What are the insulation voltage and pollution level ratings for this series?
A5: The CJX2 series contactors have a rated insulation voltage of 690V, a pollution level rating of level 3, and fall under installation category III.
Q6: What is the rated electrical endurance of the CJX2-09 contactor under AC-3 conditions?
A6: Under AC-3 operating conditions, the CJX2-09 contactor has an electrical endurance rating of 100 x 10,000 times (1,000,000 operations).
