Eaton SPD100400Y2O Surge Protection Device - UL 1449

The SPD100400Y2O delivers a 100 kAIC interrupt rating, enabling the device to clamp large surges without compromising downstream equipment protection, which translates to fewer field failures and lower maintenance costs in high-energy surge environments. This translates into tangible uptime gains for manufacturing lines and packaging operations, where unexpected surges can halt production. With a 230/400V wye (4W+G) voltage rating, the protector aligns with common industrial power architectures, reducing wiring complexity and the need for customized configurations, which shortens commissioning times and lowers project risk. Housed in a NEMA 4X enclosure with an internal disconnect and external sidemount mounting, it provides dependable protection in damp, dusty, or outdoor locations while enabling straightforward retrofit on existing distribution equipment. Operating voltages including 320 L-N, 320 L-G, 320 N-G, and 640 L-L support diversified loads, supporting motors, drives, and controllers across varied line configurations. A 15-year warranty underpins long-term asset protection, while the standard feature package accelerates installation and startup, helping facilities meet regulatory and safety benchmarks without compromising schedule or budget. This combination of rugged enclosure, clear mounting method, and solid ratings makes the SPD100400Y2O a reliable backbone for industrial protection programs, aligning with long-term maintenance plans and supplier consolidation goals. In practice, users benefit from reduced spare-part stocking, simplified procurement, and a clear, repeatable protection strategy across multiple lines and sites.
