西門子交流接觸器作為執行元件，常常被用於接通、分斷線路或頻繁的控制電動機等設備運行。交流接觸器的主要結構分別是由動、靜主觸頭，滅弧罩，動、靜鐵芯，輔助觸頭和支架外殼等零部件組成。交流接觸器的作用是當電磁線圈通電後，使動鐵芯在電磁力作用下吸合，直接或通過杠杆傳動使動觸頭與靜觸頭接觸進而接通電路。電磁線圈斷電後，動鐵芯在復位彈簧作用下自動返回，俗稱釋放觸頭並且分開電路分斷。交流接觸器是電力拖動和自動控制系統中應用*普遍的一種低壓控制電器。

交流接觸器通常採用三種滅弧方式：雙斷電弧滅弧，縱向接縫滅弧和電弧滅弧。它用於消除在分裂和閉合過程中由移動和固定觸點產生的電弧。容量超過10A的接觸器具有滅弧裝置。交流接觸器還具有輔助部件，例如反作用彈簧，緩衝彈簧，接觸壓力彈簧，傳動機構，基座和端子。

西門子交流接觸器交流接觸器的工作原理：是利用電磁力與彈簧力配合，實現觸頭的接觸和斷開。

交流接觸器具有兩種操作狀態：斷電狀態（釋放狀態）和斷電狀態（動作狀態）。

當吸引線圈通電時，靜鐵芯產生電磁吸引，銜鐵被吸入，與銜鐵連接的連杆驅動觸頭作用，使常閉觸頭斷開接觸器處於通電狀態；

當吸引線圈斷電時，利用電磁吸引力消失的原理，可以將電樞重新打開，常開觸點閉合，位置彈簧鬆開，所有觸點復位，接觸器處於斷電狀態。

西門子交流接觸器交流接觸器作用原理與接線圖二
一般三相接觸器接線一共有8個點，三路輸入，三路輸出，還有是控制點兩個。

輸出和輸入是對應的，很容易能看出來。如果要加自鎖的話，則還需要從輸出點的一個端子將線接到控制點上面。首先應該知道交流接觸器的原理。它是用外界電源來加在線圈上，產生電磁場。加電吸合，斷電後接觸點就斷開。

知道原理後，應該弄清楚外加電源的接點，也就是線圈的兩個接點，一般在接觸器的下部，並且各在一邊。其他的幾路輸入和輸出一般在上部，一看就知道。還要注意外加電源的電壓是多少（220伏或380伏），一般都標得有。

並且注意接觸點是常閉還是常開。如果有自鎖控制，根據原理理一下線路就可以了。

西門子交流接觸器交流接觸器接線參數：1、3、5接三相電源，（主電路部分）；2、4、6接三相電機。

A1、A2 是這個接觸器的線圈，接到控制電路裡面去，通過控制這個接觸器的接線線圈（A1、A2）來實現控制住電路部分的電機（以小控大）。

13、14表示這個接觸器的輔助觸點，NO表示為常開，也就是沒通電的情況下13、14是斷開的，通電後13、14是閉合的。放在控制電路部分用來自鎖（並聯在啟動按鈕上），達到連續運行的目的。
