Surge current
100 kA per phase
SPD100240H4O provides 100 kA per phase surge capability, ensuring rapid clamping of high-energy transients. That level of protection translates to fewer nuisance trips and less wear on connected equipment, improving uptime for drives, motors, and control panels. The device operates on a 240V high-leg delta (4W+G) on the B phase, aligning with common North American 3-phase distributions and enabling straightforward integration into existing panel architectures. The NEMA 4 enclosure with internal disconnect delivers weather-resistant protection and safe service isolation, reducing maintenance risk in outdoor or damp environments. UL 1449 listing guarantees compliance with widely adopted surge protection standards, giving engineers confidence in performance and reliability for mission-critical applications. Its compact footprint fits standard enclosures (3.48 in depth, 7.47 in width, 12.05 in height) and a 6.8 lb weight supports easy retrofit or new installs in tight spaces. Power Xpert SPD compatibility allows seamless extension of protection across an Eaton protection scheme, simplifying upgrade paths and training for maintenance teams.
