1. 适用范围与用途/ Application scope
NDM2 系列塑料外壳式断路器(以下简称断路器)，是本公司采用国际先进设计，制造技术研制、开发
的新型断路器之一，按照其额定极限短路分断能力(Icu)的高低，分为 C型， L 型， M 型，H型四类。
该产品具有体积小、分断高、飞弧短，抗震动的特点，是陆地及船舶使用的理想产品，其额定工作电
压至 AC 690V 额定绝缘电压为 1000V，适用于交流 50/60Hz 的电路中作不频繁转换和电动机不频繁起动
之用。
断路器具有隔离功能，相应符号为：
断路器具有过载、短路和欠电压保护功能，能保护线路及电源设备不受损坏。
本断路器可垂直安装(即竖装)，亦可水平安装(即横装)。
本产品符合标准 IEC 60947-2、GB/T14048.2。
NDM2 series of moulded case circuit breakers(Hereinafter referred to as the MCCBs), which is one
of the self-developed new generation MCCB of Nader. According to the level of the rated ultimate short-c
ircuit breaking capacity, the breaker can be classified into four types: Type C(Basic type), Type L(Stand
ard type), Type M(Less high breaking type) and Type H(High breaking type).
The breaker possesses the features such as compactness, high breaking capacity, short arc over a
nd anti-Vibration etc, which is the ideal product for both land and marine use. The rated working voltage i
sAC 690V, with the insulation voltage of 1000V, will be suitable for in-frequency switching of circuits and
starting of motors in 50/60Hz circuit.
The breaker has disconnecting function.The symbol of isolation is：
The breaker has functions of overload protection, short circuit protection and undervoltage
protection which can protect circuit and electrical power unit properly.
The breaker can be installed vertically(upright),as well as horizontally(crosswise).
The breaker meets the criterions：IEC 60947-2、GB/T14048.2。

7. 安装方式/ Mounting Method
7.1 绝缘测试
本断路器出厂前已按标准规定绝缘测试。安装前如进行复测，必须按如下步骤：
①用500VDC 兆欧表
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。
③对接至主电路的欠电压脱扣器，在进线与断路器外壳间。
④绝缘电阻不小于 20MΩ。
7.2 安装
请安装在金属阻燃物上，断路器可垂直安装，也可以水平安装。
7..1 Insulation test
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.
①500VDC tramegger
②When 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.
③Undervoltage tripper connected to the main circuit is arranged between intake wire and breaker
shell.
④Insulation resistance is not less than 20MΩ.
Notes: Insulation test could be operated after wire circuit is separated.
7.2 Install
Installed on metal or other flameproof material in vertical or horizontal mode.
垂直安装 水平安装
Vertical Horizontal

8. 附件说明书/ Accessory
8.1 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。
8.1Undervoltage 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.
8.2 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。
8.2 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.
