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。

斷路器是一種基本的低壓電器，斷路器具有過載、短路和欠電壓保護功能，有保護線路和電源的能力。主要技術(shù)指標是額定電壓、額定電流。斷路器按照不一樣的應(yīng)用具有不同有著不一樣的功能，品種、規(guī)格很多，具體的技術(shù)指標也有許多。斷路器自由脫扣：斷路器在合閘過程中的任何時刻，若是保護動作接通跳閘回路，斷路器完全能可靠地斷開，這就叫自由脫扣。帶有自由脫扣的斷路器，能夠保證斷路器合閘短路故障時，可以迅速斷開，可以防止擴大***的范圍。 </p> <p> <br /> </p> <p> <br /> </p><p> 欠電壓脫扣器是在它的端電壓降至某一規(guī)定范圍的時候，使斷路器有延時或無延時斷開的一種脫扣器，當電源電壓下降（甚至緩慢下降）到額定工作電壓的百分之七十至百分之三十五范圍內(nèi)，欠電壓脫扣器應(yīng)運作，欠電壓脫扣器在電源電壓等于脫扣器額定工作電壓的百分之三十五時，欠電壓脫扣器應(yīng)能防止斷路器閉合；電源電壓等于或大于百分之八十五欠電壓脫扣器的額定工作電壓時，在熱態(tài)條件下，應(yīng)能保證斷路器可靠閉合。所以當受保護電路中電源電壓發(fā)生一定的電壓降時，能自動斷開斷路器切斷電源，使該斷路器以下的負載電器或電氣設(shè)備免受欠電壓的損壞。使用時，欠電壓脫扣器線圈接在斷路器電源側(cè)，欠電壓脫扣器通電后，斷路器才能合閘。

真空斷路器的實際結(jié)構(gòu)中，觸頭合閘彈簧設(shè)計成即使處于分閘位置，也有相當?shù)念A(yù)壓縮量，有預(yù)壓力。這是為使合閘過程中，當動觸頭尚未碰到靜觸頭而發(fā)生預(yù)擊穿時，動觸頭有相當力量抵抗電動力，而不致于向后退縮；當觸頭碰接瞬間，接觸壓力陡然躍增至預(yù)壓力數(shù)值，防止合閘彈跳，足以抵抗電動斥力，并使接觸初始就有良好狀態(tài)；隨著接觸行程的前進，觸頭間的接觸壓力漸漸增大，接觸行程終結(jié)時，接觸壓力達到設(shè)計值。接觸行程不包括合閘彈簧的預(yù)壓縮量程，它實際上是合閘彈簧的第二次受壓行程。
