Product Description
TYD-120/100BM 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, a??380V, and used at the equipotential connection, which protects the electric network not shocked by the thunder and lightning, ita??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. Ita??s also could be replaced for the module when has operating voltage.
