Special features
Basic
The SPM250480Y1V delivers 250 kA per phase surge protection, which directly reduces the risk of transient damage to critical equipment, lowering unexpected downtime and maintenance costs in high-energy environments. This translates to measurable uptime gains and longer service life for motors, drives, and control panels in industrial facilities. The unit is a single module designed for 277/480 V Wye (4W+G) systems, simplifying integration with existing electrical infrastructure and enabling faster installation in new or retrofit projects while preserving space inside panel enclosures. Its NEMA 4X enclosure with an internal circuit breaker provides protection against dust, water, and washdown conditions, allowing installation in harsh environments without compromising safety or performance. RoHS compliance and broad certifications (UL 1449, UL 1283, CSA) ensure regulatory alignment across global operations, reducing procurement and compliance risk while supporting quality assurance programs. The 15-year warranty, extendable to 20 years when registered with Eaton, offers a clear total cost of ownership advantage by minimizing replacement cycles and warranty claim overhead. With a 50 lb footprint and 9.3 in x 17.5 in x 14.91 in dimensions, installers benefit from predictable mounting and compatibility with standard utility racks and switchgear panels. The Basic feature set from the SPD MAX series emphasizes reliability and ease of maintenance, making routine testing and replacement straightforward for maintenance teams and OEMs alike. This SPD is well-suited for protection of MCCs, motor drives, panel boards, and other critical loads in manufacturing and processing facilities, delivering protective performance without complicating existing protection schemes.

FAQs
Install the SPM250480Y1V as a single-module SPD within the panel or switchgear where 277/480 V Wye systems are fed. Mount into a suitable enclosure with proper clearances, connect line and neutral as per Eaton wiring diagrams, and ensure the internal circuit breaker remains accessible for service. Verify RoHS compliance and UL/CSA certifications are documented on site for audits. A correct installation minimizes transient exposure while enabling straightforward maintenance and testing using standard diagnostic tools.
The SPM250480Y1V delivers up to 250 kA per phase of surge protection, suitable for mitigating high-energy transients in 277/480 V systems. This rating protects motors, drives, panels, and other critical loads from external surges and switching transients, reducing the likelihood of insulation damage, nuisance trips, and unplanned downtime across manufacturing lines and processing facilities.
Yes. The unit comes in an NEMA 4X enclosure with an internal circuit breaker, designed for harsh or wet environments typical of outdoor installations and washdown areas. This rugged enclosure, combined with robust certifications, ensures reliable operation in challenging conditions while maintaining accessibility for routine inspection and testing.
The SPM250480Y1V is UL 1449 and UL 1283 listed, CSA certified, and RoHS compliant, with additional approvals noted in CSA Std. C22.2 No. 8-M1986. These certifications ensure regulatory alignment for global deployments, simplify supplier qualification processes, and support quality assurance programs across diverse facilities.
ROI stems from reduced downtime, fewer motor and drive failures due to transients, and lower maintenance costs. The 15-year warranty (20 years with registration) helps offset replacement costs, while the RoHS and certifications minimize compliance expenses and trim lifecycle risk. For facilities with frequent surges or critical loads, the SPD’s protective performance often yields a favorable payback by protecting expensive equipment and improving uptime.
