Eaton’s SPD Series (Sidemount Versions) Data Sheet
The SPD100220Y3M delivers a 100 kAIC interrupt rating, enabling it to absorb high-energy surges that commonly originate from utility faults or switching transients. This capability directly reduces the risk of downstream equipment failure and power-quality related downtime, delivering measurable improvements in line efficiency and reliability for manufacturing lines and data centers. The 127/220 V Wye (4W+G) configuration supports typical medium-voltage residential/commercial distribution while enabling seamless integration with existing electrical systems, minimizing retrofit costs and avoiding unnecessary equipment upgrades. The NEMA 1 enclosure with external side mounting simplifies installation in conditioned indoor spaces, enabling fast commissioning and reducing field labor while maintaining a compact footprint suitable for crowded electrical rooms. Standard feature package and surge counter provide immediate value: you gain ongoing visibility into surge events, improving maintenance planning and regulatory reporting. A 15-year warranty reinforces long-term ownership cost savings, while UL 1449 compliance assures safety and performance under industry standards. Compatibility with the SPD series sidemounted solutions expands install options for external-to-distribution equipment, delivering scalable protection for evolving plant needs. By combining rugged protection, straightforward installation, and proactive monitoring, this device helps facilities meet reliability targets, minimize unplanned outages, and satisfy compliance requirements in critical electrical infrastructures.
