2. 额定值是否符合使用要求，包括额定电压、额定电流、额定短路分断能力等等，上下级保护选择要合理。
3. 断路器应清洁，产品上端应无导电物质或其它非导电物质遗落。
4. 断路器安装场所应无爆炸危险、无腐蚀性气体，并应注意防潮、防尘、防震动和避免日晒。
5. 板前接线的断路器可以安装在金属骨架或绝缘板上，板后接线的断路器应安装在绝缘板上。
6. 所有电气联接是否紧固可靠，紧固件联接应根据表14扭矩要求核对。
7. 断路器进行动作特性试验时，应使用经国家有关部门检测合格的专用测试仪器，严禁利用相线直接触碰接地装置的试验方法。
装装装敬告：1. 安装断路器时应按要求,在电弧喷出方向有足够的飞弧距离,并确保相间隔弧板或护罩安装到位,进线端铜排进行了绝缘处理,以防止电弧短路。
2. 安装后应检查断路器与安装板的绝缘电阻。
如有必要对产品进行绝缘测试时,请按以下要求操作：1)用DC 500V兆欧表；2)在断路器处于闭合状态时,对断路器各极分别对地(安装箱金属外壳)间绝缘电阻进行测试;在断路器处于断开状态时,对连接在一起的电源端子与连接在一起的负载端子之间和连接在一起的所有各极带电部件与外壳之间(外壳用金属箔覆盖)分别进行测试;3)绝缘电阻应不小于10M Ω。
3. 因线路短路引起断路器动作后,应更换新的断路器且排除故障后方可投入运行。
4.在使用断路器的情况下,也应保证电气系统接地保护应完好可靠,并且装有剩余电流保护装置。
运行维护：1. 严禁湿手操作断路器，否则可能发生电击事故。
2. 断路器投入运行后，使用单位应作运行记录，并建立相应的管理制度。
3. 断路器因被保护电路发生故障(过载或短路)而分闸时，必须查明原因，排除故障后，才能进行合闸操作。
4. 断路器每六个月进行一次检查，检查时应切断电源，操作手柄使断路器合、分3次，检查机构是否可靠；检查断路器以及断路器与安装板的绝缘电阻，同时清除外壳表面尘-4-注：1. 短路分断能力级别代号:标准型(代号S)，较高型(代号H)；2. 按操作方式分:手柄直接操作(无代号)，电动操作(代号P)，转动手柄操作(代号Z)；3. 按极数分:三极(代号3)，四极(代号4)；4. 按用途分:配电保护用(无代号)；电机保护用(代号2)；5. 四极产品中性极(N)的 型式分为:C型:N极安装过电流脱扣元件，且N极与其它三极一起合分(N极先合 后分)；表1 附件名称及代号无附件报警触头分励脱扣器辅助触头欠电压脱扣器分励脱扣器、辅助触头分励脱扣器、欠电压脱扣器二组辅助触头辅助触头、欠电压脱扣器分励脱扣器、报警触头辅助触头、报警触头欠电压脱扣器、报警触头分励脱扣器、辅助触头、报警触头二组辅助触头、报警触头辅助触头、欠电压脱扣器、报警触头300308310320330340350360370318328338348368378附件名称附件代号-5-123456789T 0.3sTR Isd Ii....0.9I R 1.2I RIi (xI n 34681012OFF 2RunOFF0.5 1.0OFFNPTU126080100T (S)9010011012514015016080(A)234568OFF 1.5Isd (xI )2I 4 主要技术参数4.1断路器的额定值见表2。
