NDM3Z系列直流塑壳断路器（以下简称断路器）按功能分为NDM3Z和NDM3ZB。NDM3Z系列简

称断路器按壳架等级可分为125型、250型、250V型、250VM型、320V型、400型、630型和800型

8个等级。断路器适用于额定工作电压至DC1000V(250V型至1500V；250VM型至1100V；320V型至

1500V)，额定工作电流至800A的直流电网电路中，用来分配电能、保护电路和电源设备。NDM3ZB系

列简称断路器按壳架等级可分为125型、250型、400型和800型4个等级。断路器适用于额定工作电压

至DC250V，额定工作电流至800A的直流电网电路中，用来分配电能、保护电路和电源设备。断路器具

有过载、短路(NDM3ZB还具有短路短延时保护)和欠电压等保护功能。

The NDM3Z series of moulded case circuit breakers (Hereinafter referred to as MCCBs) is divided

into NDM3Z and NDM3ZB in according to NDM3Z series MCCBs can be divided into

seven classes according to their frame sizes, viz. Type 125, 250,250V, 250VM, 320V,400, 630 and 800.

The MCCBs are applicable for the DC grid circuit with the rated operational voltage up to

DC1000V(250V up to DC1500V；250VM up to DC1100V；320V up to DC1500V) and the rated

operational current up to 800A for electrical energy distribution, and circuit and power equipment

protection. The NDM3ZB series MCCBs can be divided into four classes according to their frame sizes,

viz. Type125,250,400 and 800. The MCCBs are applicable for the DC grid circuit with the rated

operational voltage up to DC250V and the rated operational current up to 800A for electrical energy

distribution, and circuit and power equipment MCCBs have the protecting functions in

case of overload, short circuit（NDM3ZB furfher has short circuit delay protection）, undervoltage and so

on.

断路器具有隔离功能，相应符号为/The MCCBs have the isolating function with the relative symbol：

7.4绝缘测试Insulation test

本断路器出厂前已按标准规定绝缘测试。因断路器带有电子线路板，安装前如进行复测，必须按如下

步骤：

Insulation test has been already carried out on the breaker according to standard before leaving

factory. Due to wire circuit, the following steps should be operated if insulation test is carried out on

the breaker again.

① 用500VDC兆欧表。500VDC tramegger.

② 在断路器处于断开状态，对进出连接板1-2、3-4、5-6之间，和1、3、5连接板与外壳之间（外壳用

金属箔覆盖）分别进行。When breaker is broken up, insulation test is conducted separately between

connecting panels 1-2, 3-4,5-6, connecting panels 1, 3, 5 and shell.

③ 对接至主电路的欠电压脱扣器，在进线与断路器外壳间。Undervoltage tripper connected to the main

circuit is arranged between intake wire and breaker shell.

④ 绝缘电阻不小于20MΩ。Insulation resistance is not less than 20MΩ.

注:也可分离电子线路板后进行绝缘测试。

Notes: Insulation test could be operated after wire circuit is separated.

8.3欠压脱扣器

断路器带有欠压脱扣器时，应使欠电脱扣器先通电，断路器才允许合闸.

根据外挂欠电压模块上的接线端子编号接入电源(直流电源不必区分正负极)

当电源电压下降到欠压脱扣器额定工作电压的35%～70%

范围内时，欠压脱扣器能可靠的分断断路器；当电源电压

低于欠压脱扣器额定工作电压的35%时，欠压脱扣器能防

止断路器闭合；当电源电压高于欠压脱扣器额定工作电压

的85%时，欠压脱扣器能保证断路器可靠闭合。

8.3Undervoltage tripper

When the breaker has an undervoltage tripper, the undervoltage tripper should be electrified, and

then the breaker allows switch on.

Power supply is accessed according to wiring connector number on

the external undervoltage module (anode and cathode of DC power supply

are not differentiated).

When power voltage declines to 35%～70% of the rated working

Voltage of undervoltage tripper, the undervoltage tripper can

reliably break the breaker up; when power voltage is lower than

the rated working voltage of undervoltage tripper by 35%, the

undervoltage tripper can prevent the breaker from closing; when

power voltage is higher than the rated working voltage of

undervoltage tripper by 85%, the undervoltage tripper can

guarantee the reliable closure of breaker.

8.3分励脱扣器

根据引出的导线编号接入电源(直流电源不必区分正

负极)。当分励脱扣器的外加电压介于额定控制电源电压的70%-110% 之间时，能可靠分断断路器。

8.4 Shunt tripper

Power supply is accessed according to wiring connector number on

the external undervoltage module (anode and cathode of DC power supply

are not differentiated).When impressed voltage of shunt tripper is between

70% and 110% of rated control power voltage, the breaker can be reliably

broken.
