2. L(过载电流) 设置I1=In×（0.4+0.01....0.63） In 为断路器额定电流动作时间设置等级10A：脱扣时间t1=4s I1 为断路器设定过载电流等级10：脱扣时间t1=8s 等级20：脱扣时间t1=16s 等级30：脱扣时间t1=24s 3. R(电机堵转)设置I5=I1×(3+1....7) 动作时间设置 t5=1-4-7-10s t5 为脱扣器动作的预设时间说明：R（电机堵转）保护功能可以设置关闭/开；设置关闭时把微动开关向下（OFF）位，设置开时把微动开关向上（ON）位；R 电机堵转保护功能在电机启动时是自动停用的，完成启动过程后自动恢复保护。
4. I(短路保护)设置I3=In×6.....13 5. U(缺相和三相不平衡)设置I6=0.4×I1 动作时间 t6=4s 说明：U（缺相和三相不平衡）保护功能可以设置关/开，设置关时把微动开关向下（OFF）位，设置开时把微动开关向上（ON）位；当一相或两相的电流降到低于 L 功能设定的0.4×I1 和持续时间超过 4s 时保护动作； 6.

断路器的操作一、操作断路器基本要求（1）一般情况下断路器不允许带电手动合闸。
如特殊需要时，应迅速果断，使操作机构连续通过整个行程，此时合闸信号灯应发亮。
（2）远方操作断路器时，应使控制断路器（或按钮）进行到相应的信号灯亮为止，不得快速操作后很快就返回，那样将使操作失灵。
（3）如果操作断路器后，进行的下一步操作使隔离开关，则不能以信号灯或测量仪表指示为准判断断路器是否确已真实操作完毕。
此时应至现场断路器所在地，以断路器机械位置指示器判断断路器真正开闭情况。
（4）在下列情况下，须将断路器的操作电源切断：1）检修断路器或在二次回路或保护装置上作业时。
2）倒母线过程中，须将母联断路器操作电源切断。
3）检查断路器开闭位置及操作隔离开关前。
4）继电保护故障。
5）油断路器无油，或气体断路器漏气。
6）液压、气压操动机构贮能装置压力降至允许值以下时。
7）当断路器的操作不在主控室和配电室内，在断开操作电源的同时，必须在断路器操作手柄上悬挂“不可合闸”的警告牌。
8）当系统接线从一组母线倒换到另一组母线时。
断开操作电源的办法是摘去操作回路中的操作断路器。
（5）设备停电操作前，对终端线路应先检查负荷是否为零。
对并列运行的线路，在一条线路停电前应先考虑有关整定值的调整，并注意在该线路拉开后另一线路是否过负荷。
如有疑问应问清调度后再操作。
断路器合闸前必须检查有关继电保护已按规定投入。
（6）断路器操作后，应检查与其相关的信号，如红绿灯、光示牌的变化，测量表计的指示。
装有三相电流表的设备，应检查三相表计，并到现场检查断路器的机械位置以判断断路器分合的正确性，避免由于断路器假分假合造成误操作事故。
（7）操作主变压器断路器停役时，应先断开负荷侧断路器后断开电源侧断路器，服役时顺序相反。
（8）如装有母差保护时。
当断路器检修或二次回路工作后，断路器投入运行前应先停用母差保护再合上断路器，充电正常后才能投入母差保护（有负荷电流时必须测量母差不平衡电流并应为正常）。

When max i m um busbar size of 36 mm 2 is used, maximum cable is 6 AWG (16 mm 2).Maximum tightening torque of 17.5 in-lb (2 Nm) for line/load terminals and 4.5 in-lb (0.5Nm) for ac c es s o r y device terminals.OperationMCBs are switched on by moving the handle to the upper po s i t ion. Stamped onto the handle switch, a “I” is visible con fi rming that the breaker is closed.The MCBs are “trip-free,” if the handle is being forced to the “ON” position, the breaker will still trip under fault conditions.The “O” marking indicates that the breaker is in the “OFF” position. The MCB is now open and the load is disconnected from line power.When a breaker has tripped, the MCB handle should fi rst be set to the full “OFF” position to make certain the trip mechanism has been reset. Once the fault has been determined and cleared the MCB can again be switched “ON”.MaintenanceABB miniature circuit breakers require no specialmaintenance; only normal electrical system maintenance pro c e d ures are required.Possible mounting arrangements of MCB accessoriesAuxiliary switch/bell alarmneutral disconnect Shunt trip and/or undervoltage releaseShunt trip or undervoltage release mounted with auxiliary switch14.22 Low Voltage Products & SystemsLower terminals can be bussed together with single phase or multi-phase busbars as shown.
