Type CJ19-25,32,43,63 capacitor changeover 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

For CJ19-25-43, Screws are available for installation, as well as the 35mm standard din rail
For CJ19-63-95, 35mm or 75mm standard din rail can be mounted are available for installation
When ordering, you should point out the below:
Model, rated operational voltage and frequency of coil and quantity
Example: Changeover capacitor contactor CJ19-32/11 AC 220V 50Hz 500PCS
1. Sea level heightat most 2000M
2. Ambient air temperature: -5+40
3. Relative humidity (RH): When +25,it should be less than 90%
4. No inductive dust and gas of corroding metal in air
5. Installation conditions: degree of inclination between fitting surface and vertical surface should be less than ±5
Operation And Maintenance
The inlet and outlet wire of contactor should be connected firmly in order to avoid terminal and product burned down.
When contactor closes, inrush current turns higher, and resistance is easy to be burned down,then you should change resistance to continue to use
Isolation voltage of the electric discharge parts in power factor compensation device should be no less than Ue
