Product Description
OBV7 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, ≤380V, and used at the 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, green means normal, red means abnormal. Kevin wiring mode, remote-signaling output interface. It’s also could be replaced for the module when has operating voltage.
