CM3-630L用途常熟开关断路器主要安装在低压配电柜中作主开关，用于控制和保护配电网络。其技术性能达到了国际上同类产品九十年代先进水平。符合IEC947-CM3-630/43002、GB14048.2《低压断路器》标准。CM3-630L使用条件周围空气温度为-5°C～＋40°C，且24h的平均值不超过＋35°C（特殊订货的除外）；安装地点的海拔不超过2000m；空气相对湿度在温度为＋40°C时不超过50％；在较低温度下可以有较高的相对湿度，最湿月的月平均最低温度不超过＋25°C，该月的月平均相对湿度不超过90％，并考虑因温度变化发生在产品表面的凝露；污染等级为3级。CM3-630L结构特点简介触头系统每相触头安装在绝缘小室内。触头系统采用了多片触头并联形式的结构、减小了触头系统的惯性，保证了断路器的高分断能力。操作机构安装在断路器中央，与主电路隔离；断路器由弹簧贮能机构进行闭合操作，闭合速度快。操作机构兼有电动及手动贮能、闭合、断开。所有附件整个系列通用。抽屉座摇动抽屉座下部横梁上手柄，可实现断路器的三个工作位置（手柄旁有位置指示）；“连接”位置:主回路和二次回路均接通，此时隔离板开启；“试验”位置:主回路断开。并由绝缘隔离板关闭隔开，仅二次回路接通。可进行必要的动作试验；“分离”位置:主回路与二次回路全部断开，此时隔离板关闭；抽屉式断路器具有可靠的机械联锁装置，只有在连接位置和试验位置时才能使断路器闭合；断路器共有47个二次回路接线端子；相同额定电流的抽屉式断路器（包括本体和抽屉座）具有互换性。
