Eaton’s SPD Series (Sidemount Versions) Data Sheet
Feature → Business Impact → Application: The 100 kAIC surge rating protects critical panels and switchgear from high-energy transients, reducing equipment failure and maintenance costs while extending asset life in 120/208V systems used in manufacturing lines and data centers. This translates to measurable downtime reductions and improved line availability for high-demand applications where reliability matters. Feature → Business Impact → Application: External side mounting simplifies retrofits and new installs by minimizing enclosure enclosure space requirements and hardware complexity, enabling faster project execution and easier field servicing for sidemount surge protection in electrical distribution panels. Feature → Business Impact → Application: The NEMA 4X stainless steel enclosure delivers corrosion and weather resistance for harsh environments, including outdoor or damp locations, improving long-term durability and reducing enclosure failures in outdoor substations or industrial plants. Feature → Business Impact → Application: Standard features such as a surge counter and a complete protection package enable proactive maintenance planning, enabling teams to monitor trends, schedule replacements, and demonstrate compliance during audits. Feature → Business Impact → Application: The device supports 150 L-N, 150 L-G, 150 N-G and 300 L-L operating voltages, providing comprehensive coverage for mixed-phase systems and minimizing the need for additional protection modules, which lowers total cost of ownership. Feature → Business Impact → Application: Documentation and installation resources such as installation manuals and datasheets support faster commissioning, reduce design-risk, and help meet project timelines for electrical protection projects in industrial facilities.

FAQs
For sidemount installation, ensure external mounting space on the distribution panel and adequate access for wiring, with clearances per the installation manual. Use the external side mounting method to simplify retrofits and minimize enclosure modifications. Follow UL 1449 listing guidelines and verify compatibility with 120/208V wye systems.
SPD100208Y3Q is designed for 120/208V wye (4W+G) networks, offering full protection against line-to-line and line-to-ground transients. Its 100 kAIC interrupt rating and internal surge counter provide reliable protection for panels, switchgear, and downstream loads in commercial and light-industrial environments.
By delivering a high surge current capacity (100 kAIC) and monitoring via a surge counter, the device minimizes unscheduled outages and component stress. The rugged NEMA 4X stainless steel enclosure also protects internal components in harsh environments, reducing failure rates and maintenance interruptions.
SPD100208Y3Q is UL 1449 listed, with a stainless steel NEMA 4X enclosure. It features external side mounting and supports 120/208V wye operation, with a 100 kAIC interrupt rating, aligning with industry standards for reliable surge protection and durable installation.
The standard feature package includes a surge counter to track events and aid maintenance planning. The 15-year warranty supports long-term total cost of ownership, while the UL 1449 listing and provided installation resources facilitate regular inspections and compliance checks.
