Eaton SPC100277N1P Surge Protection Device - UL 1449
Part Number: SPC100277N1P
Quick Summary
Eaton SPC100277N1P surge protection device protects electrical systems from transient overvoltage in industrial panels and machinery. Without protection, surges can cause nuisance outages, damaged components, and unplanned downtime that disrupts production. UL 1449 listed and a rugged NEMA 4X enclosure help ensure reliable operation in demanding environments, while the SPC series design supports external side mounting for flexible installations. In 277 V single-phase applications, this SPD delivers durable protection, aligning with compliance requirements and reducing maintenance costs. By choosing an SPC protector, maintenance teams gain predictable reliability, extended equipment life, and improved system uptime—key drivers for ROI in automation and electrical distribution.

100 kAIC interrupt rating delivers high surge handling to protect downstream equipment, reducing transformer insulation stress and costly failure modes in manufacturing lines. This translates to measurable uptime improvements and lower maintenance spend, especially in environments with frequent transient events. The SPC100277N1P operates at 277 V in single-phase circuits, aligning with common facility power rails and enabling straightforward integration into existing control panels without secondary power planning. The rugged NEMA 4X enclosure provides weather and corrosion resistance, allowing outdoor or damp locations to be protected without enclosure swaps or additional housings, while external side mounting offers installation flexibility and faster commissioning. With UL 1449 listed safety performance and a 10-year warranty, facilities can meet reliability targets while controlling lifecycle costs. The compact footprint (5.5 in L × 6 in H × 3.19 in W) and 2.5 lb weight simplify panel density and permit more efficient device layouts in SPC series installations. The standard configuration supports quick deployment across multiple sites, reducing engineering time and enabling scalable protection for industrial automation and electrical distribution systems.

FAQs
The SPC100277N1P is designed for straightforward integration in control panels with external side mounting. Ensure a clean, dry mounting surface and adequate clearance for the 5.5 in length and 6 in height. Verify 277 V single-phase supply compatibility and confirm proper conductor routing to minimize wiring length. With UL 1449 listing and a robust NEMA 4X enclosure, installation can proceed with standard safety practices, reducing commissioning time and risk.
Key specs include a 100 kAIC interrupt rating for robust surge handling, 277 V voltage rating in a single-phase configuration, and a NEMA 4X enclosure for environmental protection. The device is part of the SPC series and carries UL 1449 certification, supporting reliable protection in industrial power distribution while maintaining a compact footprint suitable for dense panel layouts.
Yes. The SPC100277N1P uses a NEMA 4X enclosure designed to withstand dust, water splashes, and mixings of corrosive atmospheres typical in industrial settings. Its UL 1449 listing confirms safety performance under surge conditions. This makes it suitable for outdoor installations or damp indoor environments where reliable SPD protection is essential for ongoing production.
The device occupies a compact footprint: 5.5 inches in length, 6 inches in height, and 3.19 inches in width, weighing 2.5 pounds. External side mounting provides flexible orientation options to fit crowded panels or enclosures. This compact size helps optimize panel density while delivering robust surge protection for 277 V single-phase circuits in SPC series deployments.
The SPC100277N1P carries a 10-year warranty, reflecting Eaton’s confidence in long-term reliability. This reduces lifecycle risk and can lower total cost of ownership by decreasing replacement and maintenance costs due to surge-related damage. When combined with UL 1449 compliance and a rugged NEMA 4X enclosure, the device supports predictable uptime and improved return on investment for industrial power protection programs.
