2、7）、断路器（QF）断路器不但能用于正常工作时手动通、断电路，而且当电路发生过载、短路或失压等故障时，能自动切断电路，有效地保护串接在后的电器设备。（8）、常用电气控制基础第 1 页，共 25 页学习必备欢迎下载序号类别主要品种用途1 断路器塑料外壳式断路器主要用于电路的过负荷保护、短路、欠电压、漏电压保护，也可用于不频繁接通和断开的电路框架式断路器限流式断路器漏电保护式断路器直流快速断路器2 刀开关开关板用刀开关主要用于电路的隔离，有时也能分断负荷负荷开关熔断器式刀开关3 转换开关组合开关主要用于电源切换，也可用于负荷通断或电路的切换换向开关4 主令电器按钮主要用于发布命令或程序控制限位开关
