1. 适用范围与用途/ Application scope
本断路器主要应用于交流 50/60Hz，工作电压至 AC380/400/415V，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, working voltage of AC380V/400V/415V and 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.
