RDC19B Series (AC Contactor)

RDC19B(CJ19) series switch-over capacitor contactor is suitable for the power circuit of AC50/60Hz, rated power voltage up to 660V and below, for the use of low voltage reactive power compensation equipment added-in or remove the low voltage shunt capacitor.

This contactor is equipped with a surge suppression device, and it can effectively restrain the impact of closing inrush current on capacitor and reduce the breaking instantaneous overload voltage without adding the current limiting reactor.

The contactor is fully compliant with IEC/EN60947-4-1.

Product Detail

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
