Automatically Switching Capacitors – CJ19(16)series switching capacitor contactor – LASTONE Detail:

Overview

CJ19 (16) -25, 32, 43, 63, 85, 95 switching capacitor contactors 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.It can replace the original switching device consisting of a contactor and 3 pieces of currentlimiting reactors, which is small in size and light in weight. Strong on-off capacity and easy installation

Standard： GB/T 14048.4-2010

Features
