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绿色（正常）变成红色（故障）。电涌保护器模块可在线更换。
LYD2-B series surge protective device(in short:SPD,alias:surge protector,surge arrester)is suitable for TN-S、TN-C-S、TT、IT etc.Power supply system of AC 50/60Hz,≤380，and installed on the joint of LPZOA zone or LPZOB and LPZ1zone,which protects the electric network not shocked by the thunder,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,green means normal,red means abnormal,it's also could be replaced
for the module when has operating voltage.
