The SG series surge panels are ultra-large surge capacity design for mission critical application with very high exposure to lightning. They are UL 1449 4th type 1 / type 2 tested for point-of-entry and sub-circuit protectioin.
SG series SPD is Prime's standing protector that meets the world's most important surge protection issues and solves the challenges of maintenance through maximum surge capacity. SG series has a significant advantage in abnormal over-voltage & high fault current safety and thus ensure industry’s highest level of safety and performance.
