OBV4 SPD Series
OBV4 SPD Series
Product Description
LS4 series surge protective device is suitable for TN-S、TN-C-S、TT、IT etc. power supply system of AC 50/60Hz、≤380V, and insalled on the joint of LPZIAzone or LPZOB and LPZ1 zone, which protects the electric network unshocked by the thunder, it's designed according to GB18802.1、IEC61643-1, it adopts 35mm standard raill,there is a failure release mounted in 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, The module codule be replaced depends different operating voltage.
