Surge protective devices protect against downtime, improve system and data reliability, and reduce electrical failures. Electrical surge damage can be experienced in a single event or as the result of an accumulation of power surges. Lightning and external sources cost the U.S. economy an estimated $5-6 billion per year. A common source of power surges inside a building are devices that switch power on and off.

The majority experienced between 1 to 12 hours of downtime. While 13 reported downtime greater than 48 hours caused by electrical surges. Typical applications of surge protective devices within industrial or commercial settings include: HVAC systems Generators Security systems and camera Fire alarm signaling circuits Installing surge protective devices will protect against electrical fa...
