LYD2-B系列电涌保护器

LYD2-B系列电涌保护器适用于交流50/60Hz，380V及以下的 TN-S、TN-C-S、TT、IT等供电系统，作为雷击等电位连接，其设计依据符合GB18802.1、IEC61643-1，外壳设计安装在35mm电气导轨上，该产品内置失效脱离装置，当电涌保护器因过流过热、击穿失效时，失效脱离装置能自动的将其从电网上脱离，同时可视告警指示模块由黑色（正常）变成红色（故障）。
LYD2-Bseres surge protective devie(in short:SPD,alias:surge protector,surge arrester)is suitable for TN-S、TN-C-S、TT、IT etc.pwer supply system of AC 0/60Hz.≤380V,and used at th equipotential connection,which protects the electric network not shocked by the thunder and lightning,it's designed according to GB18802.1、IEC61643-1,it adopts 35mm standard rail,there is a failure release mounted on the module of surge protective device.When the SPD fails in breakdown for over-heat and over-current,the failure release will help electric device separate from the power system and give the indication signal, Black meas normal,red means abnormal.
