AC Surge Protectors

AC line surge protection devices protect electronic, electrical, data communication and telecommunication equipment from damage caused by lightning and electrical transient surges. An AC line power spike suppression product may also be referred to as a surge protection device (SPD) or a transient voltage surge suppressor (TVSS). AC line surge arrester devices improve a system’s long-term reliability by minimizing or eliminating damage, downtime, and power disruption to electronic equipment due to transient voltage power spikes and electrical surges.

AC surge protector units are available that meet several surge protection standards for single, two, and three phase lines with voltage levels ranging from 60 VAC to 800 VAC, with various mounting options.
