1.Could be replaced for the module not need power cut.
2.Maximum current of endure the lightning stroke 20kA(8/20 μs).
3.Time of response < 25ns.
4.The color of visible window shows operating status,green means normal, red means abnormal.
CHT1-D series surge protective device (in short: SPD, alias: surge protector, surge arrecter)is suitable for TN-S,TN-C-S. TT. IT ect. Power supply system of AC 50/60Hz, =380V, installed on joint of LAP1 or LPZ2 and LPZ3, it's designed according to IEC61643-1. GB18802.1, it adopts 35mm standard rail, there is a failure release mounted on the module of suge protective device. When the SPD fails in breakdown for over-heat and over-current, the failure erelease will help electric device separate from the power 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.
