額定絕緣電壓是設(shè)計斷路器的電壓值，電氣間隙和爬電距離應(yīng)參照此值而定。有些斷路器沒有明確規(guī)定額定絕緣電壓，應(yīng)將額定工作電壓中比較大值視作額定絕緣電壓，在任何情況下，比較大額定工作電壓不超過額定絕緣電壓，伊頓穆勒塑殼斷路器NZMB1-4-A40，斷路器的額定絕緣電壓與工頻試驗電壓見表1。額定工作電壓是指通斷能力以及使用類別相關(guān)的電壓值，塑殼斷路器的額定工作電壓多為50Hz、380V，伊頓穆勒塑殼斷路器NZMB1-4-A40，伊頓穆勒塑殼斷路器NZMB1-4-A40，但也有50Hz、600V，額定工作電壓380V、50Hz的塑殼斷路器，***不允許用到660V或1140V的電源電壓上。

電器開關(guān)的分斷能力 </p> <p> 一般分為極限分斷能力Icu和運行分斷能力Ics（很多微斷不分），假如Icu=60KA，那么當線路中發(fā)生60KA的故障電流，斷路器可以安全切斷電路，而不發(fā)生觸頭熔接、等異常狀況。注意做過極限分斷的斷路器不允許再用（往往失效了），必須更換。而如果Ics=60KA，分斷該電流后，斷路器允許合閘再使用，但應(yīng)急后也須更換?，F(xiàn)在很多好的斷路器可以做到Icu=Ics。當然，對于Icu與Ics，國家有嚴格的定義與相關(guān)的試驗，以上只是簡單說說。
