Surge Protection

For Business-CriticalContinuity

Liebert® PowerSure® Panel TVSS

Surge Suppression Solutions For Distribution Panels

Electric power line disturbances such as high voltage transients can disrupt or damage sensitive electronic equipment — causing a major loss in productivity and money. Liebert understands this problem and offers the Liebert PowerSure® Panel Low and Medium Exposure surge suppression systems — the reliable way to keep these power problems from getting into your facility in the first place.

Liebert PowerSure® Panel

Low Exposure — Designed for use on branch panels or equipment in low exposure locations. Available up to 100kA/phase surge current capacity. LED status indication and Form C contacts for remote indication are standard.

Liebert PowerSure® Panel Medium Exposure— Offers protection from transients on distribution panels or any medium exposure location.

Available in 100kA/phase and 160kA/phase, all mode and two mode protection, small footprints, NEMA 12 enclosure, silver link fusing with thermal protection, all voltage and phase configurations, 5-yearwarranty.
