Protección de la transmisión del motor — CJ19 Capacitor Switching Over Magnetic Contactor 
Application:
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 overvoltagein while breaking a circuit.Moreover, It can replace transfer device which are composed of one contactor and three current limiting reactors, small, light, joins convenient and reliable, hige capacity of turning on/off.
This product conforms to GB14048.4, IEC60947-4-1 standard.
