■ 产品概述
CQM3系列塑壳断路器(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/60Hz,额定工作电压690V及以下(CQM3-63为400V),额定工作电流至800A的电路中作不频繁转换及电动机保护之用。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L型(标准型)、M型(较高分断型)三类。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。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GB/T14048.2标准要求。
■ 产品型号选型
举例:如订CQM3-125,标准型,三极,配电用,额定电流为50A并带分励脱扣器、板前接线2只,即写为订CQM3-125L/3310 50A,2只。

■ 主要技术性能指标
注:1)根据GB14048.1术语“寿命”表示电器在修理或更换部件前完成的操作循环次数的概率。
2)分别选装高为4mm(CQM3-63L/M、)、6.2mmCQM3-100L/M)、7.5mm(CQM3-250L/M)、9.5mm(CQM3-800L/M)的零飞弧罩,实现零飞弧
