摘　　要：断路器作为供配电设计中低压配电回路和控制回路使用最频繁、最重要的保护电器元件,也是保护配电网安全、可靠、经济运行和人身安全及人们生产生活用电的关键电器设备。以《低压配电设计规范》(GB50054-2011)为依据,简要阐述了低压配电线路设计中断路器的选择方法。Breaker,as the lowvoltage distribution circuit in the power supply design and the most important and frequently used electronic component to control circuit,is also the key wiring to protect the safe, reliable and economic operation of power distribution net- work, meanwhile, to protect personal safety and power demand for living and production. Based on the 〈 Code for Design of Low Voltage Electrical Installations 〉 （GB50054- 2011 ）,this paper briefly describes the selection method of breaker in the track design of low-voltage distribution.
