Product Description
OBV1-C 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, <440V, connecting the interfaces of LPZ1, LPZ2 and LPZ3. 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.
Product Features
1. Inside the SPD there are over current, over heating protection and temperature controlled open circuit technology.
2. Easy installation and easy to be replaced without the power off.
3. Small leakage current, less response time, less residual voltage.
4. Color indication window, green (normal) and red (abnormal).
5. Technology is employed with high energy and discharge gap pole (N-PE).
