Eaton SPM100480D4T SPD MAX Surge Protection - UL 1449
Part Number: SPM100480D4T
Quick Summary
The Eaton SPD MAX series surge protection device protects electrical systems from transient overvoltages in industrial and commercial mains. For engineers and maintenance teams, nuisance surges and unexpected tripping threaten uptime and equipment life. UL 1449-listed protection with a rugged NEMA 4 enclosure supports reliable operation in demanding environments. Designed for 480 Delta three-wire plus ground systems, it delivers up to 100 kA per phase while aligning with Power Xpert compatibility. This combination helps reduce maintenance costs, improve uptime, and simplify compliance reporting for industrial control panels. Coupled with a compact footprint and an internal terminal block, it streamlines installation in new builds and retrofit projects. Engineers can rely on UL 1449 compliance and the documented surge current performance to justify protection budgets and service life projections.

Feature → Business Impact → Application: The SPD MAX delivers 100 kA per phase surge protection for 480 Delta (3W+G) systems. This capability dramatically reduces the chance of phase-to-ground transients causing equipment failures and unplanned downtime. It is well suited for manufacturing lines, data centers, and critical load centers where high-energy surges are a risk. Feature → Business Impact → Application: UL 1449 listing with a NEMA 4 enclosure reinforces safety compliance and resilience against dust, moisture, and corrosion. This enables reliable operation in harsh environments and supports both indoor and outdoor installations in manufacturing plants and remote facilities. Feature → Business Impact → Application: Internal terminal block and compatibility with Power Xpert SPD networks simplify wiring and enable coordinated protection across panels, speeding installation and reducing field wiring errors. This is ideal for modular control architectures and expandable protection in evolving facilities. Feature → Business Impact → Application: The compact 9.5 in depth, 15 in width, and 17.05 in height with a 52 lb weight support dense panel layouts, reducing installation time and mounting space. This makes retrofit projects in space-constrained environments more straightforward. Feature → Business Impact → Application: 100 kA per phase protection in a 480 Delta (3W+G) configuration provides robust protection for drives, motors, PLCs, and critical loads, delivering reliable protection for industrial facilities with high transient energy and mixed-load profiles.
