Eaton’s SPD Series (Sidemount Versions) Data Sheet
High interrupt rating and voltage options are foundational features. The SPD100220Y3P delivers a 100 kAIC interrupt rating and supports 127/220 V Wye operation, with 4W+G protection and operating voltages of 150 L-N, 150 L-G, 150 N-G and 300 L-L. The business impact is clear: robust surge handling reduces the risk of device damage and extends service life for critical equipment in manufacturing lines and data centers, improving uptime and asset value. Applications include panel boards, switchgear, and outdoor distribution where transient events are common. Rugged enclosure and sidemount configuration deliver practical installation advantages. The stainless steel, NEMA 4X enclosure withstands harsh environments, while external side mounting simplifies retrofits and minimizes wiring work during installation. The business impact is faster project commissioning, lower labor costs, and easier compliance with protective coordination standards during upgrades in industrial facilities. Comprehensive protection targets all conductor paths. The SPD offers 150 L-N, 150 L-G, 150 N-G, and 300 L-L surge protection references, ensuring consistent performance across phases. This translates to higher equipment reliability, easier maintenance planning, and improved regulatory alignment for electrical installation codes in commercial and industrial settings. Standard feature package and the included surge counter give operators visibility and control. In practice, this supports preventive maintenance and incident tracking, enabling IT and facilities teams to justify capital projects with measurable ROI. The device's compatibility with external sidemount configurations also supports retrofit strategies in existing installations without major panel alterations. From an engineering perspective, sidemount SPD installations are common in automation cabinets and switchrooms where space is tight and access is critical. The SPD100220Y3P aligns with UL 1449 safety requirements and integrates into established protection schemes, reducing risk while supporting uptime commitments and long-term total cost of ownership improvements.

FAQs
The SPD100220Y3P is designed for external side mounting, which simplifies retrofits by mounting outside standard enclosures. Ensure the device is secured to a compliant surface, use proper weatherproof connections, and maintain clearances per enclosure guidelines. The NEMA 4X stainless steel housing provides weather resistance, while the sidemount configuration minimizes wiring work and reduces installation time.
Key specs include a 100 kAIC interrupt rating and a voltage rating of 127/220 V Wye (4W+G). It supports 150 L-N, 150 L-G, 150 N-G, and 300 L-L operating voltages. These attributes deliver robust surge handling for mixed-load environments, helping protect sensitive equipment in industrial and commercial panels while enabling coordinated protection with other devices.
Yes. The unit uses a stainless steel, NEMA 4X enclosure designed for harsh or outdoor environments. Combined with external sidemount mounting, it provides reliable surge protection in exposed locations, subject to proper installation clearances and weatherproof terminations. This makes it suitable for outdoor distribution cabinets and exposed industrial panels.
SPD100220Y3P carries UL 1449 certification for surge protection devices, confirming safety and performance conformance. The rugged NEMA 4X enclosure further supports compliance with protection standards in challenging environments. A 15-year warranty also reinforces long-term reliability, helping facilities justify protection investments and lifecycle budgeting.
The device provides protection against transient surges across 127/220 V systems, reducing unplanned downtime and extending equipment life. The external sidemount design accelerates retrofit projects, lowers labor costs, and enables easier field maintenance with a surge counter for monitoring. Together with UL 1449 certification and a 15-year warranty, it delivers predictable total cost of ownership improvements.
