Product Description

OBV4 series Surge Protection Device (SPD, also called surge suppressor, surge arrester) is used for TN-S, TN-C-S, TT, IT etc. power supply system of AC 50/60Hz, <380V, connecting the interfaces of  LPZOA, LPZOB and LPZ1 to prevent the thunder shock from the electric network. The design satisfies the standard of IEC61643-1, GB18802.1. It can be installed on the 35mm conducting rail. There is a failure release function deigned inside the SPD. When the SPD failed in breakdown of overheating or over current, the failure release function will be generated to separate the SPD from the power supply system and a signal is returned on the SPD color window, green means normal and red means abnormal. The failed SPD can be replaced under an 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.
Notice: When you order, please write the model and quantity carefully, for example, OBV4-80/4-385, 8 pieces.
