5.4要根据保护对象的要求，选用不同额定电流、额定剩余动作电流及剩余电流分断时间的断路器、也可根据要求选择额定剩余动作电流及剩余电流分断时间可调型漏电产品，否则达不到有效的保护作用。

六、注意事项

6.1 不要用火线对地短路或火线与零线短路的办法来试验漏电断路器，以免影响产品性能。

6.2短路器的过载、短路、保护特性出厂前已进行整定，使用中不能自行修理。

6.3对于少接线，错接线，本断路器不能有效起到漏电保护作用。

七、安全警告

7.1 断路器仅对负载侧接触相线或带电壳体与大地的漏电进行保护，对同时接触电路两线所引起的触电不能起到保护作用。

7.2 检测电路的绝缘电阻时，必须将电流回路之间的电子元件断开，否则将损坏短路器。

八、故障分析与排除见表9

表9 故障分析与排除

故障原因		原因分析	排除方式三相四线电路必须使用四极漏电断路器正确接线
误动	断路器使用不当造成误动	将三极断路器，用于三相四线电路中，由于零线中的正常工作电流不经过漏电电流互感器，只要启用单相负载断路器就会动作。断路器负载侧零线接地，会使正常工作电流经接触地点流入地造成误动四级断路器错误接线 接设备外壳
	断路器负载侧接地引起的误动
	电流和导线对地电容电流引起的误动	1）负载侧的导线紧贴地面铺设较长，存在着较大的对地电容电流；2）负载侧导线因绝缘下降，对地漏电电流增加	选用剩余动作电流稍大规格的断路器。

九、公司承诺

自产品生产日期起十八个月内，在客户正常的储运、保养、使用条件下，因产品的制造问题而不能正常使用时，提供“三包”服务。

十、订货须知

订货时必须写明：产品名称、型号、规格、极数（四极断路器零线形式）、分断能力级别、脱扣方式及附件名称、保护特性、额定电流、额定剩余动作电流，订货数量。

例如：订M1LE-250，四极(零线形式B型)，M型，配电保护用断路器，复式脱扣器，额定电流250A，额定剩余工作电流100mA，共100台。

应写为M1LE-250M/4300 B型 250A 100mA 100台。对断路器有特殊要求可与厂家协商解决。

五、附属装置的技术数据

1.辅助触头和报警触头的额定值见表

2.分励脱扣器的外加电压介于额定控制电源电压70%-110%之间时，能可靠分断断路器。

3.当电源电压下降到欠电压脱扣器额定工作电压的70%-35%范围内时，欠电压脱扣器能可靠地分断断路器；当电源电压低于欠电压脱扣器额定工作电压的35%时，欠电压脱扣器能防止断路器闭合；当电源电压高于欠压脱扣器额定宽作电压的85%时，欠电压脱扣器能保护断路器可靠闭合。

六、使用与维护

1、断路器各种特性及附件由制造厂整定，在使用不可随意调节。

2、断路器手柄可以处在三个位置，分别标示闭合断开、脱扣三种状态，当手柄处于脱扣位置时，此时不能起保护作用，在查明原因，排除故障后应向后扳动手柄，使断路器再扣，然后合闸。

3、在用户遵守保管和使用条件下，从制造厂发货之日起，不超过18个月，断路器封印完好，产品如因制造质量问题而发生损坏不能正常使用时，制造厂负责无偿更换和修理。
