1. 用途
  CM1系列塑料外殼式斷路器其額定絕緣電壓為800V(CM1-63為500V)，適用于交流50HZ，額定工作電壓690V及以下(CM1-63為400V)，額定工作電流至800A的電路中作不頻繁轉(zhuǎn)換及電動(dòng)機(jī)不頻繁起動(dòng)之用。斷路器具有過載、短路和欠電壓保護(hù)功能，能保護(hù)線路和電源設(shè)備不受損壞。
  斷路器按照其額定極限短路分?jǐn)嗄芰?Icu)的高低，分為C型(基本型)、L型(標(biāo)準(zhǔn)型)、M型(較高分?jǐn)嘈?、H型(高分?jǐn)嘈?四類。斷路器可垂直安裝，亦可水平安裝。該斷路器具有體積小、高分?jǐn)?、短飛弧(部分規(guī)格為零飛弧)、帶隔離、抗震動(dòng)等特點(diǎn)，并通過了核工業(yè)條件(1E級(jí))試驗(yàn)和船舶條件的試驗(yàn)，是國產(chǎn)產(chǎn)品中唯一能用于核工業(yè)基地的產(chǎn)品，更是陸地及船舶使用的理想產(chǎn)品。 
2.執(zhí)行標(biāo)準(zhǔn)
  產(chǎn)品符合IEC60947-2(1995)、GB14048.2《低壓斷路器》標(biāo)準(zhǔn)。
3.使用條件
  海拔不超過2000m；最大傾斜度為22.5°；
  周圍介質(zhì)溫度不高于+40°C(對船用產(chǎn)品為+45°C)和不低于-5°C；
  能耐受潮濕空氣、鹽霧、油霧、霉菌、核輻射的影響；
  在受到船舶正常振動(dòng)時(shí)能可靠工作；在受到地震情況下（4g）能可靠工作；
  在無爆炸危險(xiǎn)的介質(zhì)中，且介質(zhì)無足以腐蝕金屬和破壞絕緣的氣體與導(dǎo)電塵埃的地方；
  在沒有雨雪侵襲的地方。
