产品概述
CQM3L 系列漏电断路器(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400V, 额定电流至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,同时,能保护线路和电源设备不受损坏,还可以对过电流保护不能检测出的长期存在的接地故障可能引起火灾危
险提供保护,可对人提供间接接触保护
。在其它保护装置失灵时,额定剩余动作电流为30mA的CQM
3L断路器可对人提供直接接触附加保护。
断路器可带漏电报警不脱扣模块。避免停电造成重大损失。该断路器具有体积小、分断高、飞弧短、抗振动等特点。断路器可垂直安装(即竖装)。亦可水平安装(即横装)。断路器不可倒进线。2、4、6接负载线,即只允许1、3、5接电源线。 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CQM3L-100,四级,额定电流为80A并带电动操作机构及辅助开关,N极不安装过电流脱扣器,且N极始终接通,不与其它三极一起合分,板前接线5只,即写为订CQM3L-100P/4320A 80A 5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6mm(CQM3L-100)、7.5mm(CQM3L-225)、9.3mm(CQM3L-400)、9.5mm(CQM3L-630)的零飞弧罩,实现零飞弧。
3. 本系列三极断路器接三相负载时、否则该断路器会产生误动作,包括取自断路器负载端的负载控制回路电源也不能带中性线,负载不能带中性线。
4. 本系列三极和四极断路器接单相负载时、不要接B极,相线接A极,中性线接C极。

Note:
1: According to the IEC60947-1 term "life" denotes the probability of the number of operating cycles that an electrical appliance completes before repairing or replacing components.
2: Zero-flying hoods with heights of 6mm (CQM3L-100), 7.5mm (CQM3L-225), 9.3mm (CQM3L-400) and 9.5mm (CQM3L-630) are selected to realize zero-flying arc.
3: When this series of three-pole circuit breakers are connected to three-phase loads, the loads should not carry neutral lines, including the power supply of load control circuit taken from the load end of the circuit breaker, nor the neutral lines. Otherwise, the circuit breaker will malfunction.
4: When this series of 3poles and 4poles circuit breakers are connected to single-phase loads, the phase wiring is connected to pole A, the neutral wiring is connected to pole C, not to pole B.
