Unlike traditional surge protectors, APC's Power-Saving SurgeArrest reduces energy consumption by smartly managing power to electronics while still protecting them from harmful surges and spikes. It helps lower energy bills through the use of Master/Controlled outlets that automatically shut power off to unused peripherals, like printers, scanners and speakers, when not in use. By turning off power to these "phantom loads", the P7GT can save an average of $25 per year on the electric bill per system it is protecting and will pay for itself in less than two years time!
