CJ19 Changeover capacitor Ac contactor

CJ19 Series changeover capacitor contactor is especially used for low voltage shunt capacitor switching. And it widely used in reactive power compensation equipment in which AC 50HZ, voltage 380V, inrush current system in the contactor can decrease shock to capacitor and lower switching overvaluation while breaking a circuit.Moreover, It can replace transfer device which are composed of one contractor and three current limiting reactors, small, light, joins convenient and reliable, high capacity of turning on/off.
These series contactor  conforms to IEC60947-4-1 standard.

CJ19 series AC Contactor is suitable for using in the circuits the rated voltage up to 400V AC 50Hz or 60Hz. CJ19 is used to combine with low voltage reactive power compensators or cut off low voltage shunt capacitor. CJ19 series AC Contactor has restraining device to effectively decrease impact caused by inrush transient current when switch on or over voltage when switch off.

2. Altitude: The equipment is suitable for installation below an altitude of 2000m to ensure its adaptability to various geographical locations.

3. Atmospheric conditions: In an environment with a temperature of 40°C, the relative humidity of the atmosphere should not exceed 50%. However, at lower temperatures, higher relative humidity may be allowed.
