Power gap lightning protection device

 Application range: LZA-30A/50A are applied to equipotential bonding of the low voltage side of transformer or main low voltage distribution boxes inside the building, providing protection against the overvoltage arising fromthe lightning strike to power supply system of class I or faulty operation,but they are not applied to the systemof the expected short-circuit current beyond rated breaking afterflow current. The series fuse must be at the front-end of the product, otherwise, the surge protector may be burned out by the developed power flowcurrent, while the product is discharging.(option from standard IEC61643-1 and GB50343)
