Product Description
OBV4 series surge protection 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, <380V, and installed on the joint of LPZOA zone or LPZOB and LPZ1 zone, 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 protection device. When the SPD fails in breakdown for over-heat and over-current, the failure release will help electric device separate from the power supply 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.
