ActiveLow-voltage surge protective devices－Part 22:Surge protective devices connected to telecommunications and signalling networks－Selection and application principles
低压电涌保护器 第22部分：电信和信号网络的电涌保护器 选择和使用导则
Application Summary AI generated
This standard provides selection and application principles for surge protective devices (SPDs) specifically designed for telecommunications and signaling networks operating at low voltages. It is applied by engineers and system designers to ensure proper SPD coordination, performance, and safety in data, voice, and control circuits within telecom infrastructure, industrial automation, and building management systems. The guidance covers installation locations, voltage protection levels, and compatibility with network equipment to prevent damage from transient overvoltages.
