RDC5 Series (AC Contactor)

The RDC5 series AC Contactor is primarily designed for AC circuits with a frequency of 50Hz or 60Hz, featuring a maximum rated voltage of 690V and a maximum rated current of 95A. It is utilized for remotely switching circuits on and off, and can also be directly integrated with a thermal relay to form an electromagnetic starter, which serves to protect circuits prone to overload operations. Additionally, the contactor can be fitted with accessories including the block typeauxiliary contacts group, air delay contact, mechanical interlock mechanism, etc. to combine intodelay contactor,directional contactor, and star-delta starter.

This product complies with the EC/EN60947-4-1 standard.

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