交流接触器是广泛用作电力的开断和控制电路。它利用主接点来开闭电路，用辅助接点来执行控制指令。主接点一般只有常开接点，而辅助接点常有两对具有常开和常闭功能的接点，小型的接触器也经常作为中间继电器配合主电路使用。 交流接触器的接点，由银钨合金制成，具有良好的导电性和耐高温烧蚀性。LC1D188MD 施耐德交流接触器，南京梅莱原装供应！
基本组成
交流接触器主要有四部分组成:(1) 电磁系统、包括吸引线圈、动铁芯和静铁芯；(2)触头系统、包括三组主触头和一至两组常开、常闭辅助触头、它和动铁芯是连在一起互相联动的；(3)灭弧装置、一般容量较大的交流接触器都设有灭弧装置、以便迅速切断电弧、免于烧坏主触头；(4)绝缘外壳及附件、各种弹簧、传动机构、短路环、接线柱等。
工作原理
陆:输配电设备网,当线圈通电时、静铁芯产生电磁吸力、将动铁芯吸合、由于触头系统是与动铁芯联动的、因此动铁芯带动三条动触片同时运行、触点闭合、从而接通电源。当线圈断电时、吸力消失、 动铁芯联动部分依靠弹簧的反作用力而分离、使主触头断开、切断电源。
