The Emerson Network Power 425 is a compact surge protective device that offers protection in each connected mode–line to neutral, line to ground, neutral to ground or line to line and line to ground. The 425 uses thermally protected MOVs, is designed in a NEMA 4X enclosure, and is tested as a UL 1449 Type 1 device, so it can be placed on the line or load side of the main disconnect. The compact design and extensive testing makes this device ideal for most panel and equipment locations.
