低压电涌保护器（SPD） 第12部分：低压配电系统的电涌保护器 选择和使用导则
Application Summary AI generated
This standard provides guidelines for selecting and applying surge protective devices (SPDs) in low-voltage power distribution systems up to 1000V AC or 1500V DC. It is used by electrical engineers and system designers to determine appropriate SPD types, voltage protection levels, and coordination requirements for protecting equipment in residential, commercial, and industrial installations against transient overvoltages from lightning or switching operations.
