Unverified90% confidenceDecision RuleTime unknown

额定电流必须根据被保护电机的满载电流和启动浪涌倍数计算选取，选小了会因启动电流频繁熔断，选大了则失去过载保护意义

Unverified标称额定功率外还需关注峰值/浪涌功率，电机类电器(冰箱压缩机、水泵、电动工具)启动瞬间电流是运行时的3-7倍，额定功率够但峰值不足仍会触发过载保护82% similar Unverified选购稳压器容量时应按用电设备额定功率的1.5-2倍留余量，尤其带电机、压缩机的设备（冰箱、空调、水泵）启动电流可达运行电流的3-5倍，容量不足会导致频繁保护或烧毁77% similar
