Surgelogic Type XDSE systems are designed to provide highquality surge suppression for a wide variety of commercial, industrial or institutional applications. With a high-energy parallel design, this range is able to provide all modes of suppression at 150,000 peak Amps of surge current rating per phase. Each Metal Oxide Varistor (MOV) is individually fused with patented overvoltage technology to withstand superior overvoltage for systems with unstable power, without compromising transient clamping performance. This unit is intented for installation on the load side of the service equipment using a 3 phase Wye connection for higher reliability.
