Type 2 3-Phase Surge Panel with Replaceable Surge Modules



277/480VAC 3-Phase Wye, Surge Panel with Replaceable Surge Modules: 277-7M3 (3) & 8320-GN (1), NEMA 12 Enclosure, UL 1449 4th Edition Compliant

Leviton’s Surge Protection Devices can be used individually or as part of a coordinated application strategy, to protect sensitive electronic equipment, in industrial, commercial and residential locations, from the stress and degradation inflicted by voltage transients. Leviton Surge Protection Devices are compliant with UL 1449 Standards. Leviton’s outstanding Surge Protection Devices divert damaging voltage transients, or surges, away from electronic equipment. Transients are diverted away from sensitive micro circuitry, providing protection against catastrophic failure, costly downtime and data disruptions.
