NDM5-160 系列塑料外壳式断路器（以下简称断路器） ，额定绝缘电压为 800V，适用于交流 50Hz 或 60Hz，额
定工作电压 AC230V、AC400V、AC690V，额定工作电流 16A 至 160A 的电路中，用来分配电能，同时对线路及电源
设备的过载、短路、欠电压(带欠压脱扣器的)起保护作用。也可以对电动机的不频繁启动、制动、过载、短路等
起保护作用。
With rated isolation voltage of 800V , NDM5-160 series moulded case circuit breaker (hereinafter referred to as
breaker) is applied to a circuit with alternate current of 50Hz or 60Hz,rated working voltage of AC230V , AC400V,
AC690V ,and rated working current of 16A to 160A, in order to allocate electric energy, protect circuit and power
appliance in the condition of overload, short circuit and under voltage (having undervoltage tripper),as well as protect
motor in the case of infrequent start, break, overload and short circuit.

额定工作电压 AC400V、AC690V，额定工作电流 160A 的电路中，用来分配电能，同时对线路及电源设备的过
载、短路、欠电压(带欠压脱扣器的)起保护作用。
With rated isolation voltage of 800V , NDM5-160 series moulded case circuit breaker (hereinafter referred to as
breaker) is applied to a circuit with alternate current of 50Hz or 60Hz,rated working voltage of AC400V , AC690V ,and
rated working current of 160A, in order to allocate electric energy, protect circuit and power appliance in the condition of
overload, short circuit and under voltage (having undervoltage tripper).
NDM5Z-160 系列塑料外壳式断路器（以下简称断路器）, 额定绝缘电压为 1200V，适用于额定工作电压
DC500V（2P 串联） 、DC750V（3P 串联） 、DC1000V（4P 串联） 、DC1200V（4P 串联） ，额定工作电流 16A 至
160A 的电路中，用来分配电能，同时对线路及电源设备的过载、短路、欠电压(带欠压脱扣器的)起保护作用。
With rated isolation voltage of 1200V , NDM5-160 series moulded case circuit breaker (hereinafter referred to as
breaker) is applied to a circuit with rated working voltage of DC500V (2P serial connection), DC750V (3P serial
connection), DC1000V (4P serial connection),DC200V (4P serial connection),and rated working current of 16A to 160A,
in order to allocate electric energy, protect circuit and power appliance in the condition of overload, short circuit and
under voltage (having undervoltage tripper).
