1. 适用范围与用途/ Application scope
本断路器主要应用于交流 50/60Hz，额定工作电压 415V，额定工作电流至 630A 的电路中作不频繁转
换及电动机不频繁起动之用。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，
同时还可以对过电流保护不能检测的长期存在的接地故障可能引起的火灾危险和人身触电提供保护。
The breaker is mainly applied to infrequent changeover in a circuit with alternate current of 50/60Hz, rated
working voltage of 415V and rated working current to 630A, and to the infrequent start of electric motor. The
breaker has overload, short circuit and undervoltage protection functions that can prevent the line and power unit
from being damaged while protecting the possible fire danger and electric shock by the long-term failure of
ground connection which fails to be detected by overcurrent protection.

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。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：
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。
注:也可分离电子线路板后进行绝缘测试
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 70%～35%
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 70%～35% 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.

9. 使用和维护/ Application & Maintenance
1)断路器各种特性及附件由制造厂整定，在使用过程中不可随意调节
onfigured by the manufacturer, all characteristics and accessaries of the breaker are not adjustable.
2)断路器手柄可以处于三个位置，分别表示闭合、脱扣、断开三种状态，当手柄处于脱扣位置时，要使断
路器闭合就必须先向分闸方向扳动手柄使断路器再扣，然后合闸
Breaker handle can be put in three positions: closed, tripped and broken states. When the handle is in tripped
position, the breaker can be closed only by pulling the handle in opening direction to fasten the breaker and then
closing.
3)维护检查必须有专业技术人员负责
Maintenance and check should be finished by professional technicians.
4)用户如需选用内、外附件，按所订型号由本公司提供，以保证质量。如用户自行选购或改装，本公司不
