Eaton’s SPD Series (Sidemount Versions) Data Sheet
Feature → Business Impact → Application: The SPD100220Y1P delivers a 100 kAIC interrupt rating, providing robust protection against high-energy surges that can compromise drives, controllers, and sensors. This translates to reduced equipment failures and longer asset life, especially on critical automation lines and feeder panels. Application: Ideal for 127/220 V wye (4W+G) systems in industrial plants where transient events are common and downtime is costly. Feature → Business Impact → Application: External side mounting enables quick installations alongside distribution equipment, minimizing panel space usage and simplifying retrofits in retrofit projects or new builds. Application: Data centers and manufacturing cells where space is at a premium and fast deployment matters. Feature → Business Impact → Application: NEMA 4X stainless steel enclosure provides corrosion and washdown tolerance, extending service in challenging environments such as chemical processing or dusty manufacturing floors. Application: Outdoor enclosures, utility cabinets, and harsh plantrooms. Feature → Business Impact → Application: 150 L-N, 150 L-G, 150 N-G, 300 L-L operating voltages offer versatile protection across common 3-phase and single-phase configurations, reducing design complexity and stock variety. Application: Retrofit of mixed-voltage feeders or new builds requiring flexible surge protection. Feature → Business Impact → Application: 15-year warranty and UL 1449 certification reduce lifecycle risk and warranty disputes for maintenance managers. Application: Procurement and service contracts seeking predictable long-term protection. The combination of these features supports measurable efficiency gains, improved compliance with safety standards, and a clear ROI in uptime and asset protection.

FAQs
The SPD100220Y1P is designed for external side mounting, allowing installation alongside distribution gear without opening the main panel. Begin by selecting a sturdy, accessible location on the equipment enclosure, align mounting holes, and secure with appropriate hardware. Connect line and ground conductors per the 127/220V wye configuration, verify clearances, and finalize installation with the included basic feature package.
Key specs include a 100 kAIC interrupt rating, voltage rating of 127/220 V (Wye, 4W+G), and operating voltages of 150 L-N, 150 L-G, 150 N-G, and 300 L-L. This combination supports robust surge diversion for most industrial feeders and control circuits while maintaining compatibility with external side mounting and NEMA 4X enclosures.
Yes. The unit uses a stainless steel NEMA 4X enclosure designed for harsh environments, including outdoor installations and washdown areas common in manufacturing, food processing, and chemical processing facilities. This protects internal components while maintaining reliable surge protection performance.
SPD100220Y1P carries UL 1449 certification, indicating compliance with recognized safety standards for surge protective devices. This designation helps satisfy procurement specifications and regulatory expectations for electrical protection in commercial and industrial systems.
The device is backed by a 15-year warranty, providing long-term protection against device failure and a defined support window for maintenance planning. Routine inspections and periodic verifications of wiring, enclosure integrity, and contact connections are recommended to sustain optimal protection performance.
