5SJ6?系列標準型?小型斷路器
小型斷路器是用于低壓電氣設備，保護導體、開關及電器，防止過載和斷路的，能夠滿足與電氣設備相關的各種條件，代表了各個行業中技術性能及經濟性最佳的解決方案，廣泛應用于工業、政府設施高技術公共設施及家電等行業。
西門子斷路器是按照現行國際標準（IEC60898）制造的，分為7個產品系列，覆蓋范圍為電流0.3A-125A，電壓230/400V，同時可按與之相關的附件及輔助開關進行分類。它們用搭鎖安裝在符合EN50022及DIN46277標準的35mm的對稱護攔上。
?主要功能特點：
1.?采用漏斗式組合型接線端子使接線簡單可靠；可方便地連接匯流母線排，并可以通過附加接線端子使進線或出線的端子容量達35mm2
2.?觸頭系統采用銀合金材料(銀錫或銀石墨)，真正做到了無熔焊。
3.?采用快速滅弧系統，由動觸頭鎖定片、引弧導板、磁吹金屬片和金屬滅弧柵片等部鉤傘Ｃ鴰∈抑杏卸啻?3片的金屬柵片，可迅速將電弧熄滅，平均短路分斷時間僅為3.7?ms。
4.?能量限制等級比?3?還要高(能量值僅為等級?3?的50%)。
5.?選擇性配合保護好。可與上級的熔斷器，塑殼式斷路器等產品形成良好的選擇性保護。
6.?斷路器均能滿足IEC898的標準，分斷能力最高可達10KA（如用于工業IEC947－2標準最高達25KA。
7.?斷路器脫扣特性有A、B、C、D四種，額定電流范圍從0.3－125A。可以適用于各種不同的使用范圍
8.?斷路器的外殼采用熱固性材料制成，具有很高的耐熱性和抗沖擊強度，絕緣強度高。
9.?斷路器外形為標準模數化結構，體積小重量輕；安裝部件采用金屬片和彈簧，可以安全牢固地卡裝在35mm的標準導軌上。
10.?斷路器可與多種附件相連接，如用于手柄鎖定的鎖定裝置，它可以防止無關人員去操作斷路器，另外還有輔助開關、故障報警開關、分勵脫扣、欠壓脫扣等附件可供選擇。
