Eaton SPD100480Y3K Surge Protection Device - UL 1449
Part Number: SPD100480Y3K
Quick Summary
The Eaton SPD100480Y3K surge protection device provides reliable transient suppression for 277/480V four-wire systems. Engineers face nuisance trips and equipment damage from voltage transients, especially in motor drives, automation panels, and critical distribution gear; this model helps by delivering a 100 kAIC interrupt rating and a rugged NEMA 1 enclosure with external sidemounting for straightforward retrofits. It carries UL 1449 listing, aligning with essential industry protection standards, and is designed for indoor installation in controlled spaces. For businesses, this translates into reduced downtime, longer equipment life, and predictable maintenance costs, while installation benefits from standard feature packaging and surge counter for easy monitoring and regulatory compliance.

FAQs
Plan for external sidemount mounting on indoor surfaces and ensure clearance for the 9.5 in length and 5.4 in width. Use a reinforced mounting surface in a controlled environment to protect the NEMA 1 enclosure from dust and accidental contact. Review the installation manual for wiring access and surge counter integration to avoid interference with other distribution equipment.
The 100 kAIC interrupt rating is rated to absorb and divert large transient energy away from protected circuits, reducing the likelihood of damage to conductors, breakers, and connected loads. This translates to lower repair costs, fewer unplanned outages, and extended life for downstream devices in demanding industrial environments.
Yes. The device is specified for 277/480V wye configurations with four wires plus ground (4W+G) and supports L-N, L-G, N-G, and L-L operating voltages. It is designed for indoor, panel-integrated protection, making it a strong fit for modern industrial control panels and distribution boards using those voltages.
The SPD100480Y3K carries UL 1449 certification, indicating compliance with recognized surge protection standards for electrical equipment. This certification provides assurance of performance under surge conditions, supports regulatory alignment, and simplifies procurement decisions for safety-conscious facilities and OEMs.
Investing in the SPD100480Y3K yields ROI through reduced downtime, lower replacement costs, and extended equipment life thanks to robust surge protection. The built-in surge counter aids maintenance planning by informing when protection is active or nearing end-of-life, while the 15-year warranty lowers total cost of ownership in long-term deployments.
