CJX2-09~95 Series (AC Contactor)

The CJX2 Series AC Contactor is built for 50Hz/60Hz AC circuits, supporting up to 690V rated voltage and 95A rated current, enabling safe remote circuit connection and disconnection.

It can be directly paired with thermal relays to form an electromagnetic starter for effective overload protection. Additionally, it’s compatible with optional accessories (block-type auxiliary contact groups, air-delay contacts, mechanical interlock mechanisms) to be configured as delay contactors, directional contactors, or star-delta starters for specialized industrial needs.

Fully compliant with IEC/EN 60947-4-1 standards, this contactor meets global safety and performance benchmarks for industrial electrical systems.

Normal Operating Condition and Installation 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 not exceed 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
