Eaton SPM120220Y1R SPD MAX surge protection device - UL 1449

120 kA per phase surge protection provides robust transient suppression, protecting downstream devices from lightning and switching surges. This translates to fewer unplanned outages and lower replacement costs for drives, PLCs, and sensitive electronics in manufacturing lines. Ideal for data centers, control cabinets, and outdoor enclosures, this capability helps maintain process availability and reduces maintenance cycles. With a NEMA 4 enclosure and an internal circuit breaker, the SPD MAX supports rugged indoor and outdoor installations and simplifies service. The integrated breaker enables quick isolation for maintenance without additional hardware, while the weather-resistant housing protects the electronics from dust, water, and washdowns. This reduces downtime and streamlines installation in harsh environments. Its 127/220 V Wye (4W+G) configuration aligns with common industrial power distribution, enabling straightforward integration with existing panels and feeders. The single-module design keeps wiring simple and minimizes panel footprint, which is valuable in space-constrained environments. Compatible with three-phase systems and mixed loads, it supports reliable protection for motors, sensors, and drives. UL 1449 and UL 1283 listings, along with CSA Electrical Notices, and RoHS compliance, assure regulatory alignment across North America. This certification suite helps procurement teams meet electrical safety and environmental requirements while avoiding redesign costs. By choosing a RoHS-compliant SPD MAX, you also support sustainable product stewardship. Warranty coverage extends 15 years from delivery, growing to 20 years when registered on Eaton's SPD site, lowering long-term ownership risk. The extended service life reduces replacement cycles, lowers maintenance labor costs, and improves total cost of ownership for capital projects. For projects with strict uptime targets, the protection is a clear, long-term value. At 9.3 in depth, 14.91 in width, and 17.5 in height, with a 50 lb weight, the SPM120220Y1R occupies a substantial, but manageable footprint in control rooms and outdoor cabinets. The compact form in a rugged NEMA 4 housing supports easier mounting and wiring inside existing architectures. This helps engineers meet space and serviceability requirements without compromising protection.
