Product Description
CNC High Quality Cj19I 380V 3 Poles Capacitor Changeover AC Contactor 50/60 Hz
CJ19i contactor for capacitor switching (hereinafter called contactor) is suitable for the circuit of AC 50Hz/60Hz with rated rated voltage up to 690V. It is mainly used to add low voltage reactive power compensation equipment or cut off low voltage parallel capacitor. The contactor is equipped with a device to suppress the inrush current, which can effectively reduce the impact of the making inrush current on the capacitor and suppress the over-voltage when the capacitor is cut off.
Standard: IEC/EN 60947-4-1
