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。

690V,

 

with

 

the

voltage

 

of

 

1000V,

 

will

 

be

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。
