Surge current
100 kA per phase
High surge capability is built in with 100 kA per phase, which significantly reduces the risk of damaging transient events. This translates to fewer replacement components, lower downtime, and improved uptime for mission-critical loads in manufacturing lines and data centers. In practice, you’ll see fewer nuisance interruptions when motors, drives, and PLCs ride through brief surges on 120/208 V systems. Built for harsh environments, the SPD is housed in a NEMA 4 enclosure with an internal disconnect, simplifying field service and enabling safe, weather-resistant installation. Its compact dimensions and weight of roughly 6.8 lb support straightforward mounting in panels, switchgear, or wall-mount configurations, reducing space and labor during installation. Seamless integration with Eaton's Power Xpert SPD family ensures coordinated protection across the distribution network. The 120/208 V wye configuration supports typical commercial and light industrial power systems, while the 4W+G arrangement keeps line-to-ground protection straightforward for grounding schemes. UL 1449 certification provides recognized safety and performance validation for surge protection devices, while the rugged enclosure supports long service life in harsh sites. Installation follows standard wiring practices, with clear labeling and compatibility with internal disconnects that speed maintenance and testing. While the upfront investment is modest, the SPD reduces maintenance costs by preventing surge-related failures and extending downstream equipment life. By minimizing unplanned downtime and simplifying inspection routines, facilities realize a favorable ROI over the asset life cycle.
