Fig. 1 Control panel of NDM3EU-225/400 controller
3.2.2 NDM3EU 控制器控制面板各部分功能 Functions of each part in control panel of NDM3EU controller
(1)测试端口 Test port
即“TEST”端口,NDM3EU 专用测试仪通过该端口与控制器相连,进行测试及调试等操作。
That is, the "TEST" port, the NDM3EU dedicated tester is connected to the controller through this port for
testing and debugging operations.
(2)电流、时间调节旋钮 Current and time adjustment knob
可通过电流、时间旋钮的调节,选择适当的组合以达到保护线路、保护设备的作用。此项操作必须由
专业技术人员进行。
注: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 400、Tr 整定为 12s 时,当主回路电流为 2×400A 时,断路器将持续 12s 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
I——表示过载情况下,主回路实际电流值。
The current and time knobs can be adjusted to select the appropriate combination to protect the circuit and
protect the device. This operation must be performed by a professional technician.
Note: Tr indicates the breaker operating time when the actual current is twice the Ir setting value.
For example, when Ir is set to 400 and Tr is set to 12s, when the main circuit current is 2×400A, the circuit
breaker will continue to open the main circuit after 12s. The operating time accuracy is ±10%.
With overload current, the time when the circuit breaker opens the main circuit follows the formula:
t= (2*Ir/I)2*Tr
I—— indicates the actual current value of the main circuit with overload conditions.
3.2.3 指示灯 Indicator light
(1)电源指示灯 Power
控制器处于工作状态时指示灯闪亮。
The indicator light flashes when the controller is in operation.
(2)过载指示灯 Overload
过载指示灯常亮时,表示实际电流超过了过载长延时整定电流值 Ir 的1.15 倍,处于过载状态,并经
一定的时间后断路器将断开

When the overload indicator is always on, it means that the actual current exceeds 1.15 times of the overload
long delay setting current value Ir, which is in an overload state, and the circuit breaker will be disconnected after
a certain time.

2)过载长延时具有热记忆功能,在产品脱扣后的 30min(NDM3EU-225)/20min(NDM3EU-400)内有效
(NDM3EU-225 需要 DC24V 辅助电源)
当第一次脱扣的能量是 QT =(2 * Ir)2* T 时,T是行程时间。 能量 Q1 在间隔 T1 = QT×T1 / Tthm
时损失,第二次脱扣所需的能量为 Q0,即第二次脱扣时间为 t =(QT-Q1)/(2 * Ir)2; 有关热记忆功能,
请联系制造商
The overload long delay has a thermal memory function, which can be activated 30minutes (NDM3EU-225)
/ 20 minutes (NDM3EU-400) after the tripping of the circuit breaker .(NDM3EU-225 requires DC24V auxiliary
power supply to realize this function).
When the energy of the first trip is QT = (2 * Ir) 2* T, T is the trip time. The energy Q1 lost at interval T1 =
QT×T1/Tthm, the energy required for the second trip is Q0, that is, the second trip time is t = (QT - Q1) / (2* Ir) 2;
For thermal memory function, please contact the manufacturer.
3)短路短延时保护(见表 6)Short circuit short-time delay protection (Table 6)
短延时保护防止配电系统的阻抗性短路。分成两段:反时限段,定时限段。

8.3 if circuit breakers are equipped with auxiliary contacts, when the circuit breakers are operated to on or off,
signal from the auxiliary contacts should be switched normally.
8.4 断路器正常无需维护,但是建议每年按如下进行一次维护:
A) 维护前确保断路器分闸,断开电源与断路器的连接(包括主电路及辅助电路),将断路器移离安装
位置;
B) 断路器合闸状态下按下紧急脱扣按钮,再扣断路器,合、分断路器,以确认断路器操作机构是否
可靠;
C) 清洁隔弧板,如有必要,则更换相间隔板;
D) 检查所有的连接情况,用纱布擦除氧化物,用可溶解清洁剂清洁,拧紧螺栓和螺母
8.4 Normally, circuit breaker doesn’t need maintenance. However we strongly recommend doing
maintenance as below once a year.
A) Before maintenance, make sure that circuit breaker is at off position; disconnect the breaker and power
supply, including all main or secondary circuit. Remove the breaker from the place it was installed.
B) Press the trip button, when breaker is at on position, and then releash, switch-on and off to make sure
whether the mechanism is reliable.
C) Clean the insulation partitions or change them if necessary.
D) Inspect the entire connection situation, wipe the oxidation with guaze, clean and tighten the screws and
nuts with dissolvable detergent.
