Eaton SPM400208Y3S Surge Protection Device - UL 1449 Certified

High surge capacity protects critical loads. The SPM400208Y3S delivers up to 400 kA per phase for 120/208 V Wye systems, enabling fast clamping of transients and lower peak stresses on drives, PLCs, and instrumentation. This capability translates to reduced downtime, longer device life, and lower maintenance costs in manufacturing lines and facility electrical rooms. Modular two-module architecture provides scalable protection and easier service. If a module needs testing or replacement, downtime is minimized and spare parts management becomes simpler, making it ideal for main or branch panels in motor control centers, data centers, and campus facilities. Surge counter standard supports proactive monitoring. The built-in counter lets teams track surge events over time, enabling targeted maintenance and improved risk management. Rugged NEMA 4 enclosure with internal circuit breaker simplifies installation and reduces the need for additional enclosures, while enabling safe operation in dusty, humid, or washdown environments. Compliance and safety are reinforced by RoHS, UL 1449, UL 1283, and CSA listings, easing procurement across regulated industries. Warranty of 15 years (20 years with registration) improves total cost of ownership and long-term value for industrial buyers and electrical contractors.
