低压大容量电动机控制回路中低压断路器的选用

The Selection & use of Low Voltage Relay Devices in the Circuit Controlled by Powerful Generators with Low Voltage

对低压大容量电动机控制回路中低压断路器的合理选用进行了探讨

The rational selections for relay devices with lower voltage in the circuit controlled by generators with lower voltage but large capacity have been illnstrated here.
