Description
Switching capacitor contactor CJ19 (16) -25, 32, 43, 63, 85, 95 are used to switch low voltage shunt capacitors. They are widely used in reactive power compensation equipment with 380V 50Hz.
The contactors are equipped with a device to restrain inrush current, which can effectively reduce the impact of closing inrush current on the capacitor and reduce the switching overvoltage at the moment of disconnection.
Switching capacitor contactor CJ19 can replace the original switching device consisting of a contactor and 3 pieces of current-limiting reactors, which is small in size and light in weight. Strong on-off capacity and easy installation
