Eaton SPM100220Y4R Surge Protection Device - UL 1449
Part Number: SPM100220Y4R
Quick Summary
Eaton SPD MAX surge protection device protects critical electrical systems from transient surges in industrial facilities. This helps avoid unplanned outages and costly equipment damage caused by transient spikes. UL 1449 certification ensures surge safety, and the NEMA 4 enclosure with an internal circuit breaker provides rugged protection in harsh environments. For engineers and maintenance teams, the SPM100220Y4R offers 127/220 V Wye (4W + G) compatibility and straightforward mounting in control panels or cabinets. By standardizing on a single SPD family—Power Xpert SPD—maintenance and spares simplify, driving lower inventory costs and faster outage resolution. This translates to improved uptime, simpler procurement, and a safer, standards-aligned protection strategy across facilities.

FAQs
Installing the SPM100220Y4R in an existing panel is straightforward due to its 9.5 in depth, 17.05 in height, and 15 in width footprint and 52 lb weight. It uses 127/220 V Wye (4W + G) with UL 1449 listing. Ensure panel cutouts and mounting hardware fit, and connect ground and line terminals per the Eaton guide for a secure, code-compliant installation.
100 kA per phase indicates the device’s maximum transient current it can safely divert per phase without degradation. This rating translates to stronger protection for high-energy surges, reducing the likelihood of equipment damage in demanding environments such as machine zones and data-center adjacencies. It complements the 127/220 V Wye configuration for broad compatibility.
Yes. The SPM100220Y4R is designed for industrial protection of power distribution in environments with frequent transients. Its UL 1449 listing, 100 kA per phase capability, 127/220 V Wye configuration, and NEMA 4 enclosure make it a strong fit for data centers’ ancillary panels and heavy manufacturing control rooms where uptime and reliability are critical.
The SPM100220Y4R carries UL 1449 listing, which validates safety and performance under surge conditions. It also features a NEMA 4 enclosure and internal circuit breaker, supporting rugged, weather-resistant installation. These certifications help streamline audits, facilitate design approvals, and ensure consistent protection across industrial facilities.
Investing in SPD protection yields ROI through reduced unplanned downtime, fewer equipment replacements due to voltage transients, and lower maintenance costs. With high surge capacity, standardized Eaton protection, and compatibility with Power Xpert SPD ecosystems, projects benefit from faster commissioning, simplified spare-part management, and longer asset life in manufacturing and distribution environments.
