斷路器的接線方式有板前、板后、插入式、抽屜式，用戶如無特殊要求，均按板前供貨，板前接線是比較常見的接線方式。插入式接線：在成套裝置的安裝板上，先安裝一個斷路器的安裝座，安裝座上六個插頭，斷路器的連接板上有六個插座。安裝座的面上有連接板或安裝座后有螺栓，安裝座預(yù)先接上電源線和負(fù)載線。運用時候，將斷路器直接**安裝座。若斷路器壞了，只要拔出壞的，換上一只好的即可。它的更換時間比板前，板后接線要短，且方便。因為插、拔需要一定的人力。所以國內(nèi)的插入式產(chǎn)品，其殼架電流限制在較大為400A。從而節(jié)省了維修和更換時間。插入式斷路器在安裝時應(yīng)檢查斷路器的插頭是否壓緊，并應(yīng)將斷路器緊固，來減少接觸電阻，提高可靠性。

真空斷路器毫無例外地運用對接式接觸方式。動觸頭碰上靜觸頭之后就不能再前進(jìn)了，觸頭接觸壓力是由每極觸頭壓縮彈簧(有時稱作合閘緩沖彈簧)提供的。所謂接觸行程，就是開關(guān)觸頭碰觸開始，觸頭壓簧施力端繼續(xù)運動至終結(jié)的距離，亦即觸頭彈簧的壓縮距離，故又稱壓縮行程。接觸行程有兩方面作用，一是令觸頭彈簧受壓而向?qū)佑|頭提供接觸壓力；二是保證在運行磨損后仍然保持一定的接觸壓力，使之可靠接觸。通常接觸行程可取開距的百分之二十到三十左右，10kV的真空斷路器約為3～4mm。
