52277-7MS
277/480VAC 3-Phase WYE, 7-Mode, Type 2 Panel Mounted Surge Protective Device with Integral Disconnect Switch and Replaceable Surge Modules: 277-7M3 (3) & 8320-GN (1)
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.
