Eaton SPM120220Y3X Surge Protector - UL 1449

Max series protection from Eaton delivers robust surge handling with a single module rated at up to 120 kA per phase, making it suitable for demanding industrial feeders. The SPM120220Y3X uses a 127/220 V Wye (4W+G) configuration to shield three-phase, four-wire systems typical of modern power distribution panels, drives, and PLC racks. With a standard surge counter, clear event history, and a compact footprint, this SPD minimizes nuisance tripping while preserving service continuity. In practice, this means quieter operation, longer motor life, and better protection for sensitive equipment on manufacturing lines and data-processing racks. Designed for harsh environments, the unit features a NEMA 4X enclosure with an internal terminal block that streamlines wiring and reduces panel clutter. The internal block also improves safety by enclosing terminals and enabling faster, error-free field connections. Its substantial dimensions—9.3 in depth, 14.91 in width, 17.5 in height—and a 50 lb weight indicate a rugged, installer-friendly footprint that remains serviceable in both indoor and protected outdoor spaces. Maintenance and lifecycle costs are lowered by the built-in surge counter, which provides visible wear trends and simplifies compliance reporting. Eaton backs the SPD with a 15-year warranty from delivery, extending to 20 years when registered on the Eaton SPD site. This warranty redundancy translates to lower total cost of ownership and predictable budgeting for replacement cycles in critical lines. Compliance and compatibility ensure risk management across facilities: RoHS compliant, UL 1449, UL 1283 certifications, plus CSA recognition for electrical notice alignment. The SPM120220Y3X plugs into Eaton's SPD ecosystem and follows standard 127/220 V protection practices for 120/240 VAC networks. This alignment supports regulatory compliance, safer installations, and simplified procurement for electrical distributors, engineers, and maintenance teams.
