CJX4-kd系列切换电容器接触器（以下简称接触器）主要用于交流50Hz（或60Hz）， 额定绝缘电压为690V， 在AC-6b使用类别下，额定工作电压为400V时额定工作电流至87A的低压无功功率补偿设备中，通断低压无功功率补 偿用的电容器组，用以调整电系统的功率因数COSΦ值。接触器附有抑制涌流 装置，能有效地减少合闸涌流对电容器组的冲击和降低操作过电压。
CJX4-Kd range contactor for capacitor switching in used in AC 50Hz(or
60Hz), rated insulation voltage 690V, rated current is up to 87A under rated voltage 400V and category AC-6b of low-voltage no power compensation device, for adjust power factor COSΦContactor attached inhibit flow device that can effectively reduce impact from trip flow and reduce operation over- voltage.
