介紹：

電動機(jī)熱磁斷路器的保護(hù)功能主要由熱磁保護(hù)元件提供。?熱元件?通過感溫雙金屬片產(chǎn)生推力，達(dá)到一定位移促使斷路器脫扣。?電磁元電動機(jī)熱磁斷路器通常采用模塊結(jié)構(gòu)，方便加裝輔助觸頭、報(bào)警觸頭、欠電壓脫扣器和分勵脫扣器等附件。其保護(hù)功能包括過載保護(hù)件?則通過鐵心、線圈、磁軛、銜鐵等組成，當(dāng)短路電流通過導(dǎo)體在鐵心的磁系統(tǒng)中形成強(qiáng)大的電磁場時，銜鐵被吸合使斷路器脫扣?。和短路保護(hù)。過載保護(hù)通過熱動式元件實(shí)現(xiàn)，而短路保護(hù)通過電磁式元件實(shí)現(xiàn)
