This product is suitable for lightning and surge protection of single-phase, three-phase power lines of lightning protection zone LPZ1 or LPZ2 to LPZ3 (grade D or III). Vital components of this product adopt the advanced high capacity surge absorber member MOV，and have passed the burn-in screen with stable quality and quick response time. Product in series is superior to that of parallel connection in protective property. It has lower output voltage limit and can protect the equipment effectively. With LC filter circuit and current limiting device, its protection grade can reach IP30. This kind of product is of complete function, convenient installation, and the function of operating light as well as fault detection.
