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 250A、TR整定为 100s 时,当主回路电流为 2³250A 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=(2³IR/I)2³TR(其中 I表示过载情况下,主回路实际电流值)
2. T 型、GT 型只能通过电脑上位机通讯软件调整整定值。
3. 电动机保护型面板,(2)整定是与其他类型的控制器的整定方法不同,两旋钮相加后的值作为最
后整定的值,若相加的和超过 In,则直接按 1倍的 In 来计算。
4. 电动机保护型断路器,如在脱扣等级规定的时间范围内,若累积的能量超过(7.2×IR)2×Class,则提
前脱扣,若小于前面约定的值,且至脱扣等级时间到时,电流仍未降至 1.5 IR以下,则在脱扣等级规定的
时间到时,立即脱扣;在脱扣等级时间外,断路器脱扣的动作时间按公式 t=(7.2×IR/I)2×Class 计算。
5. 电流不平衡率选择 OFF 时,控制器同时也关闭了断相保护功能,电流不平衡率的计算是,三相电
流的最大值与三相电流最小值的差值,与三相电流的平均值之间的比值,即为三相电流的不平衡率。
6. 短路短延时功能,在脱扣等级规定的时间内是关闭的,在脱扣等级规定的时间过后,短路短延时
功能才被打开。
Notes: 1.TRindicates the operating time of the breaker when actual current is twice of IRsetting.
E.g.: when IRand TRare set as 250A and 100s respectively, when the current in main circuit reaches
2³250A, 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=(2³IR/I)2³TR(Of which, I stands for the actual current
in the main circuit under overcurrent.)
2. The setting values of T type and GT type breakers can only be adjusted through
communication software of the upper computer.
3. The motor protection type panel ,(2) settings are not the same as those of other types
of controllers. The values of the two buttons are added as the final setting value. If the sum
is more than In, Then directly by 1 times the In to calculate。
4. If the accumulated energy exceeds (7.2 ×IR) 2×Class for a period of time specified
in the tripping rating, the motor-protective circuit-breaker shall be tripped in advance. If
it is less than the value specified in the previous paragraph and the time until the tripping
time.The current is not reduced to 1.5 IRor less, then the time specified in the tripping rating
to the time, immediately tripping; outside the tripping time, the circuit breaker tripping time
according to the formula t = (7.2 ×IR/ I ) 2x Class。
5. When the current unbalance rate is OFF, the controller also shuts off the phase protection
function. The calculation of the current unbalance rate is the difference between the maximum
value of the three-phase current and the minimum value of the three-phase current and the average
value of the three-phase current between three-phase current unbalance。
6. Short-circuit Short delay function, which is switched off within the time specified
in the tripping rating , after the time specified in the tripping rating has elapsed, the
short-circuit short delay function is switched on。
3.2.2.3 指示灯 Indicator light
(1)预报警指示灯 Pre-alarm light
预报警指示灯黄灯闪亮时,表示实际电流超过了预报警电流 Ip的整定值,经特定时间后黄灯将由闪
亮转为恒亮。
(2)过载指示灯 Overload light
过载指示红灯恒亮时,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。
(1)Flashes of pre-alarm indicator light indicate that actual current has exceeded setting value
for pre-alarm current Ip. After certain duration, the flashes will turn into constant
illumination.
(2)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.

3.2.2.4 NDM3E 控制器通讯功能 Communication function of NDM3E controller
NDM3E 通讯功能通过外挂式通讯模块来实现“四遥”功能。该通讯模块可将断路器的相关信息经现场
总线传至上位机,上位机通过通讯模块下发指令操作电动操作机构,从而控制断路器的合、分。
The communication function of NDM3E can achieve “Four-remoteness”functions through the
external hanging communication modules. The communication module can transfer relevant
information of the breaker to upper computer through on-site bus, and then the upper computer
can use the instructions released by the communication module to operate the motor-operated
mechanism, and achieve closing and opening of the control breaker.
通讯模块上传的信息包括:Information uploaded by the communication module includes:
²断路器设备代码;Equipment code of the breaker;
²断路器各参数设定值;Setting values of the breaker’s parameters;
²断路器的合、分状态;Closing and opening state of the breaker;
²通过断路器每极的实时电流。Real-time current passing through each pole of the breaker
NDM3E 断路器通讯接口的现场总线规约为:Modbus—RTU。
The on-site bus protocol of NDM3E breaker’s communication port: Modbus—RTU
注:通讯型断路器(T型、GT 型)默认波特率为 9600、通讯地址为 3。
Notes: The default baud rate of the communication breaker (T type and GT type) is 9600, and the communication
address is 3.

3.2.2.5 NDM3E 专用测试仪 Special tester for NDM3E
使用 NDM3E 专用测试仪器通过控制器上的“TEST”端口与断路器本体相连。可对控制器进行故障测定、
数据记录、脱扣试验等操作。
When connecting “TEST”terminal on the controller and breaker by using special tester for
NDM3E. The tester can be used for testing failures of the controller, recording data, and tripping
tests etc.
3.2.2.6 NDM3E 控制器过载报警不脱扣功能 Alarm without trip for overload of NDM3E controller
当NDM3E 控制器上的 TR档位设置为“OFF”时,断路器具有过载报警不脱扣功能。即在线路过负荷的
情况下,断路器不跳闸仅输出过负荷信号。保障了供电的连续性,满足 GB 50054 中第 4.3.3 条“突然断
电比过负载造成的损失更大的线路,其过负载保护应作用于信号而不应作用于切断电路”的要求。该功能
可有效替代热继电器报警,节约成本。
When TR shift on the NDM3E is set as “OFF”, the breaker has the function of alarm without
tripping for overload, namely in the case of overload on the circuit, the breaker only outputs
overload signals with tripping, which can ensure continuity of powering supply, meeting
requirements of Section 4.3.3 in GB 50054: In the circuit where the sudden disconnect of power
supply can bring larger losses than overload, and the overload protection shall act on the signals
other than disconnecting the circuit. The function can effectively substitute thermo-relay alarm
for saving costs.

如连接不正常则请用鼠标点击软件界面的“断开连接”按键后重新设置好配套参数或检查接线是否正确后
再次连接,直到通讯连接正常。
Run "MCCB communication system.exe" software provided by Shanghai Nader Electrical Co., Ltd.
(see Fig.6) and set the parameters: COM port, baud rate, sub-station address (The parameters
include baud rate and sub-station address need to be the same with the connected breaker. Factory
default settings: baud rate 9600 and sub-station address 3). After setting the parameters, click
the "Connect" button on software interface, if communication link is working correctly (see Fig.
7), communication status light will be on; if not, please click the "Disconnect" button on software
interface, reset parameters and connect again after you make sure wiring is correct until the
communication link is working correctly.
