CJX1 (AC Contactor)

The CJX1 Series AC contactor is engineered for AC circuits operating at 50Hz or 60Hz,with rated operating voltage up to 690V. When used in the AC-3 category and rated current up to 400A, it offers a rated operating voltage is 380V, enabling safe remote circuit connection and disconnection. It can also be paired with JRS2 (3UA) to form an electromagnetic starter, protecting circuits from operational overloads.

This product fully complies with IEC/EN60947-4-1 standards.

Note:1.The default combination of auxiliary contact is “2NO 2NC"; 2.Auxiliary contact for above 32A can be: “3 NO 3NC" or “4NO 4NC"

Normal Operating Condition an Dinstallation Condition

1.Ambient temperature:+5℃~+40℃, average temperature within 24h does not exceed +35℃

2.Altitude: does not exceed 2000m

3.Atmospheric condition: when the highest temperature is +40℃, the relatively humidity does notexceed 50%; it can allow relatively high humidity when it is at relatively low temperature, for instance, it reaches 90% when it is at +20℃, it should take measurement when there have condensation occurred due to the temperature variation

4.Pollution grade:3

5.Installation category:Ⅲ

6.Installation position: the gradient of the mounting surface to the vertical surface does not exceed ±5°

7.lmpact and vibration: product should be installed and used at the places without obvious shake,impact and vibration
