SurgeArrest provides more features, performance and value than any other same-class surge suppressor. SurgeArrest is designed for multimedia applications and desktop systems including computers, CD ROM drives, monitors, printers, fax machines, modems and more. SurgeArrest is equipped with a fast acting fuse that reacts quickly to lightning strikes and other catastrophic surge events. In addition, a thermal fuse shuts your system down in the event of a dangerous wiring fault. In both cases, SurgeArrest actually blocks errant power from reaching your equipment if the surge components are damaged. The PRO7 is a Professional SurgeArrest that’s a 7-outlet floor model.
