适用范围：
CJ19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、额定工作电压至380V的电力线路，供低压无功功率补偿设备投入或切除低压并联电容器之用。接触器带有抑制涌流装置，能有效地减小合闸涌流对电容的冲击和抑制开断时的过电压。
结构特点：
接触器为直动式双断点结构，触头系统分上下两层布置，上层有三对触头与限流电阻构成抑制涌流装置，当合闸时它先接通经数毫秒之后工作触头接通，限流触头中永久磁块在弹簧反作用下释放，断开限流电阻，使电容器正常工作，接触器内部电路连接图(见图)。 CJ19-25-43的接触器有两对辅助触头，CJ19-63-95的接触器有三对辅助头。接触器接线端有绝缘罩覆盖，安全可靠，线圈接线端带有标出电压数据可防止接错。CJ19-25-43接触器可用螺钉安装，也可借底部的滑块扣装在35mm标准卡轨上。面罩上一个可拆卸的长方形小牌，用户可用它打印项目代号等。CJ19-63-95可用35mm或75mm标准卡轨安装。
