Description

OVR BT2 series Surge Protection Device (in short: SPD, alias: Surge Suppression, Surge Arrester) is suitable for TT, IT, TN-S, TN-C-S etc. power supply system of AC 50/60Hz, <380V, installed on the joint of LPZ1 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 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 system and give the indication signal, white means normal, red means abnormal, it's also could be replaced for the module when has operating voltage. Product Features1.Could be replaced for the module not need power cut.2.Maximum current of endure the lightning-stroke 70kA(8/20μs).3.Response Time <25ns.4.The color of visible window shows operating status, white means normal, red means abnormal.
