conduct testing and debugging etc.
3.2.2.2 整定电流、整定时间调节旋钮 Adjusting knob for setting current 、setting time and tripping
rating 可通过电流、时间的调节，选择适当的组合以达到保护线路、保护设备的作用,此项操作应由专
业技术人员负责。
Suitable combinations of current and time are adjusted by this knob, so as to protect circuits and
devices. This operation should be done by specialized technical personnel.
注：1.Tr 表示当实际电流为 Ir 整定值的 2倍时，断路器动作时间。
如：当 Ir 整定为 400A、Tr 整定为 100s 时，当主回路电流为 2×400A 时，断路器将持续 100s 时后断
开主回路。动作时间精度为±10%。在过载电流下，断路器断开主回路的时间遵循以下公式：
t=(2×Ir/I)2×Tr （其中 I表示过载情况下，主回路实际电流值）
Notes: 1.Tr indicates the operating time of the breaker when actual current is twice of Ir setting.
E.g.: when Ir and Trare set as 400A and 100s respectively, when the current in main circuit reaches
2× 400A, the breaker will disconnect the main circuit after lasting for 100s. The time precision of
action is ±10%. Under the overcurrent, the time that the breaker disconnects the main circuit shall
follow the following format: t=(2×Ir/I)2×Tr(Of which, I stands for the actual current in the main circuit
under overcurrent.)

过载指示灯快速闪烁时(频率 4Hz)，表示在 3次脱扣动作仍未导致产品脱扣。
Constant light of overload indicator indicates that actual current is more than 1.5 times of
overload long-time delay current setting Ir. The breaker will break the circuit after certain duration.
When the overload indicator flashes fast（frequency is 4Hz），it indicates that the 3 trip has not
caused the product tripped.
（2）电源指示灯 Power light
电源指示灯慢速闪烁时(频率 1Hz)，表示正常运行；
电源指示灯快速闪烁时(频率 4Hz)，代表控制器自检或系统运行过程中检测到故障。
When the overload indicator flashes slow(frequency is 1Hz)，it indicates that the system is
running normally；
When the overload indicator flashes fast (frequency is 4Hz)，it indicates that self-checking of
the controller or failure detected during the system operation.
注：两种指示灯应在每半年进行一次常规检验。
Note: Two indicator lights should have once routine inspection per half a year.
