SACE E2B 20 3 ph斷路器一般由觸頭係統、滅弧係統、操作機構、脫扣器、外殼等構成。
當短路時，大電流（一般10至12倍）產生的磁場克服反力彈簧，脫扣器拉動操作機構動作，開關瞬時跳閘。當過載時，電流變大，發熱量加劇，雙金屬片變形到·定程度推動機構動作（電流越大，動作時間越短）。
有電子型的，使用互感器採集各相電流大小，與設定值比較，當電流異常時微處理器發出信號，使電子脫扣器帶動操作機構動作。
斷路器的作用是切斷和接通負荷電路，以及切斷故障電路，防止事故擴大，保證安·運行。而高壓斷路器要開斷1500V，電流為1500-2000A的電弧，這些電弧可拉長至2m仍然繼續燃燒不熄滅。故滅弧是高壓斷路器·須解決的問題。
吹弧熄弧的原理主要是冷卻電弧減弱熱遊離，另一方面通過吹弧拉長電弧加強帶電粒子的復合和擴散，同時把弧隙中的帶電粒子吹散，迅速恢復介質的絕緣強度。
低壓斷路器也稱為自動空氣開關，可用來接通和分斷負載電路，也可用來控制不頻繁起動的電動機。它功能相當於閘刀開關、過電流繼電器、失壓繼電器、熱繼電器及漏電保護器等電器部分或全部的功能總和，是低壓配電網中一種重要的保護電器。
低壓斷路器具有多種保護功能（過載、短路、欠電壓保護等）、動作值可調、分斷能力高、操作方便、安·等優點，所以被廣泛應用。結構和工作原理低壓斷路器由操作機構、觸點、保護裝置（各種脫扣器）、滅弧係統等組成。
低壓斷路器的主觸點是靠手動操作或電動合閘的。主觸點閉合後，自由脫扣機構將主觸點鎖在合閘位置上。過電流脫扣器的線圈和熱脫扣器的熱元件與主電路串聯，欠電壓脫扣器的線圈和電源並聯。當電路發生短路或嚴重過載時，過電流脫扣器的銜鐵吸合，使自由脫扣機構動作，主觸點斷開主電路。當電路過載時，熱脫扣器的熱元件發熱使雙金屬片上彎曲，推動自由脫扣機構動作。當電路欠電壓時，欠電壓脫扣器的銜鐵釋放。也使自由脫扣機構動作。分勵脫扣器則作為遠距離控制用，在正常工作時，其線圈是斷電的，在需要距離控制時，按下起動按鈕，使線圈通電。
