Model CJ19、CJ19B and CJ19C switching capacitor contactors(hereafter called“the contactor“for short)are the coutartors specially used for making and breaking of low voltage shunt capacitors and widely used in reactive power used for making and breaking of capacitor up to 60kvar in electric power system of AC 50Hz and rated working voltage 220~380V for the purpose of power factor．
结构特征 Structure
接触器为双断点直动式运动结构，动作机构灵活，手动检查方便，结构紧凑。触头、磁系统采用封闭结构，粉尘不易进入，能提高寿命。接线端均有防护罩覆盖，使用安全可靠。安装可用螺钉紧固，也可扣装在35 毫米或75 毫米的安装轨上，装卸迅速方便。
Double-break contacts direct-action campaign structure,movement organizations flexible, manually check compact structure. Contact,the magnetic system uses the closed structure,the dust is not easy to enter,can increase life expectancy.Shield terminals are covered,safe and reliable.Install fastening screw can also be installed in the deduction of 35 mm or 75 mm mounting rail,loading and unloading quick and easy.

注：① CJl6 型可以用CJl9 型代替。
② CJl9C 型的基本技术性能与CJ19B 型相同, 不同之处为电阴电路在完成抑制涌流作用之后即与电路脱离。
Note: ① Model CJl9 can substitute for Model CJl6．
② The basic technical function of model CJl9C is the same as model CJl9B，but the difference is that the former will switch off the circuit after its resistor circuit finishes controlling surge current．
