用途
CM1塑壳断路器,CM1系列塑料外壳式断路器其额定绝缘电压为800V(CM1-63为500V)，适用于交流50HZ，CM1塑壳断路器额定工作电压690V及以下(CM1-63为400V)，额定工作电流至800A的电路中作不频繁转换及电动机不频繁起动之用。断路器具有过载、短路和欠电压保护功能，能保护线路和电源设备不受损坏。
断路器按照其额定极限短路分断能力(Icu)的高低，分为C型(基本型)、L型(标准型)、M型(较高分断型)、H型(高分断型)四类。断路器可垂直安装，亦可水平安装。该断路器具有体积小、高分断、短飞弧(部分规格为零飞弧)、带隔离、抗震动等特点，并通过了核工业条件(1E级)试验和船舶条件的试验，是国产产品中唯一能用于核工业基地的产品，更是陆地及船舶使用的理想产品。
2.执行标准
产品符合IEC60947-2(1995)、GB14048.2《低压断路器》标准。
3.使用条件
海拔不超过2000m；最大倾斜度为22.5°；
周围介质温度不高于+40°C(对船用产品为+45°C)和不低于-5°C；
能耐受潮湿空气、盐雾、油雾、霉菌、核辐射的影响；
在受到船舶正常振动时能可靠工作；在受到地震情况下（4g）能可靠工作；
在无爆炸危险的介质中，且介质无足以腐蚀金属和破坏绝缘的气体与导电尘埃的地方；
在没有雨雪侵袭的地方。 -
