1. 用途
 BKM1塑殼斷路器系列塑料外殼式斷路器其額定絕緣電壓為800V(CM1,63為500V)，BKM1塑殼斷路器適用于交流50HZ，BKM1塑殼斷路器額定工作電壓690V及以下(CM1,63為400V)，BKM1塑殼斷路器額定工作電流至800A的電路中作不頻繁轉換及電動機不頻繁起動之用。斷路器具有過載、短路和欠電壓保護功能，能保護線路和電源設備不受損壞。
  斷路器按照其額定極限短路分斷能力(Icu)的高低，分為C型(基本型)、L型(標準型)、M型(較高分斷型)、H型(高分斷型)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、高分斷、短飛弧(部分規格為零飛弧)、帶隔離、抗震動等特點，并通過了核工業條件(1E級)試驗和船舶條件的試驗，是國產產品中唯一能用于核工業基地的產品，更是陸地及船舶使用的理想產品。 
2.執行標準
  產品符合IEC60947,2(1995)、GB14048.2《低壓斷路器》標準。
3.使用條件
  海拔不超過2000m；最大傾斜度為22.5°；
  周圍介質溫度不高于+40°C(對船用產品為+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時能可靠工作；在受到地震情況下（4g）能可靠工作；
  在無爆炸危險的介質中，且介質無足以腐蝕金屬和破壞絕緣的氣體與導電塵埃的地方；
  在沒有雨雪侵襲的地方。
