Eaton's PSPV series is a commercial grade and light industrial surge protective device (SPD) that combines surge suppression components and EMI/RFI filtering, providing effective protection for sensitive electronic loads. Surges (also known as transients) due to lightning, utility grid switching, switching of external/internal inductive or capacitive loads, and other sources travel on power line conductors throughout the electrical distribution system, causing system operating problems and equipment downtime. Use of the PSPV units can prevent these costly occurrences and equipment damage. The PSPV can be installed on the main of light commercial buildings, on any subpanel in a facility and in any control panel to protect sensitive electronic equipment.
