Do you know where surge productive device (SPD)use?

微信图片_20221115151402The ZY2-20/40/60/80/100 series surge protective device SPD,is suitable for TN-S,TN-C-S,TT,IT etc.power supply system of AC 50/60Hz,≤380V,Its designed according to IEC61643-1,GB18802.1,it adopt 35mm standard rail,there is failure release mounted on the module or 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 indioation signal,green means normal,red means abnormal,Its also could be replaced for the module when has operating voltage.
