When the SPD fails in breakdown for over-heat and over-current, the failure release will help electric device separate from the power supply 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. Model and Meaning   Application Scope and Installation Position OBV4 series surge protection devices is suitable for B grade lightning protection, installed on the joint of LPZOA zone or LPZOB and LPZ1 zone, which protects the electric network not shocked by the thunder or surge over voltage. OBV4-60, OBV4-80, OBV4-100 are usually installed in low voltage main distribution box connected to the incoming end of the buildings.
