CM1系列塑料外壳式断路器（以下简称断路器），是本公司采用国际先进设计、制造技术研制、开发的新型断路器之一。其额定绝缘电压为800V，适用于交流50Hz，额定工作电压690V及以下，（CM1-63为400V），额定电流至800A的电路中作不频繁转换及电动机保护（CM1-800无电动机保护型）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。该断路器具有体积小、分断高、飞弧短（部分规格零飞弧）、抗振动等特点，并通过了核工业条件（1E级）试验和船舶条件的试验，成为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。
本断路器可垂直安装（即竖装），亦可水平安装（即横装）。
本断路器具有隔离功能，其相应的符号为：“ 。
断路器符合IEC60947-2、GB14048.2标准。
2.适用工作环境
