B型脫扣特性：脫扣電流為（3～5）In，適用于住戶配電系統(tǒng)，家用電器的保護和人身安全保護； </p> <p> C型脫扣特性：脫扣電流為（5～10）In，適用于保護配電線路以及具有較高接通電流的照明線路和電動機回路； </p> <p> D型脫扣特性：脫扣電流為（10～20）In，適用于保護具有很高沖擊電流的設(shè)備，如變壓器、電磁閥等； </p> <p> K型脫扣特性：具備1.2倍熱脫扣動作電流和8～14倍磁脫扣動作范圍，適用于保護電動機線路設(shè)備，有較高的抗沖擊電流能力。高海拔環(huán)境下塑殼斷路器熱脫和穩(wěn)定性研究。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

空氣斷路器，又名空氣開關(guān)，是斷路器的一種。是一種只要電路中電流超過額定電流就會自動斷開的開關(guān)。空氣開關(guān)是低壓配電網(wǎng)絡(luò)和電力拖動系統(tǒng)中非常重要的一種電器，它集控制和多種保護功能于一身。除能完成接觸和分?jǐn)嚯娐吠?，尚能對電路或電氣設(shè)備發(fā)生的短路、嚴(yán)重過載及欠電壓等進行保護，同時也可以用于不頻繁地啟動電動機。 </p> <p> 空氣斷路器的主要作用 </p> <p> 在正常情況下，過電流脫扣器的銜鐵是釋放著的；一旦發(fā)生嚴(yán)重過載或短路故障時，與主電路串聯(lián)的線圈就將產(chǎn)生較強的電磁吸力把銜鐵往下吸引而頂開鎖鉤，使主觸點斷開。欠壓脫扣器的工作恰恰相反，在電壓正常時，電磁吸力吸住銜鐵，主觸點才得以閉合。一旦電壓嚴(yán)重下降或斷電時，銜鐵就被釋放而使主觸點斷開。當(dāng)電源電壓恢復(fù)正常時，必須重新合閘后才能工作，實現(xiàn)了失壓保護。
