Today's business environment calls for 24x7 uptime and reliability. Customers require solutions to ensure that their investment in equipment and processes are protected from the damaging effects of voltage transient and electrical noise. Surge protection devices are needed to protect sensitive telecommunications, HVAC, and other electrical and electronic equipment.

This Powerware TVSS product line consists of two products: Powerware PVL and Powerware PXL.

The Powerware PVL is our standard surge protective device (SPD) that combines surge suppression components and EMI/RFI filtering to provide effective protection for sensitive electronic loads. The Powerware PVL product is available in 50, 80, 100, 120, 160, and 200 kA per phase.

The Powerware PXL offers improved quality and reliability including enhanced monitoring capabilities and a new patent pending technology - our Thermo-Dynamic Fusing ™System - which provides a safer surge protective device in a smaller package. It can be purchased in 100, 120, 160, 200, 250, 300, 400, and 500 kA per phase sizes.
