When selecting the appropriate voltage protection level value of the surge protective device low-voltage lightning surge protector, the surge tolerance of the protected equipment (or the impact immunity of key equipment) and the nominal voltage of the system should be considered. The lower the voltage protection level value, the better its protection performance; (under the same parameter conditions, selecting an surge protection device low-voltage lightning surge protector with a lower Up will have a better protection effect).
