Surge current
100 kA per phase
High surge current rating of 100 kA per phase provides robust transient protection, directly reducing the risk of equipment damage during voltage spikes. The business impact is fewer downtime events, longer life for motors and drives, and lower repair costs across manufacturing and processing lines. This protection pairs well with 120/240V split-phase systems, making it a practical choice for control panels and distribution boards in facilities with standard commercial power. The result is improved reliability and predictable maintenance budgeting for mission-critical equipment across industrial processes.Integrated with the Power Xpert SPD family, SPD100240S4L supports plug-and-play compatibility and straightforward replacement. The business impact is simplified procurement, reduced labor during installation, and consistent protection across existing Eaton protection schemes. Applications include retrofit projects and new builds where standardized surge protection is a requirement for NEC compliance and protective coordination with upstream devices.NEMA 1 flush enclosure minimizes footprint and enables safe indoor mounting. The business impact is improved space planning and safer installation in crowded electrical rooms or equipment cabinets. Applications include OEM panel builds and service desks where indoor exposure and unobtrusive mounting are priorities, enabling faster onboarding of protection devices without sacrificing access or compliance.Compact dimensions (3.48 in depth, 7.47 in width, 12.05 in height) and a 6.8 lb weight support easy handling and field installation. The business impact is reduced installation time and safer handling in busy facilities, boosting on-site productivity. This suits distribution panels, motor control centers, and power distribution units where space efficiency and quick swaps are valued during maintenance cycles.
