80 kAIC interrupt rating provides high-energy surge handling, reducing downstream equipment damage and unplanned outages; this directly improves line uptime and prolongs the life of motors and drives used in automation. The 277/480V wye (4W+G) voltage rating matches common plant power distribution, enabling seamless integration with minimal system reconfiguration and lowering the risk of misapplication. The NEMA 1 flush enclosure with external side mounting simplifies installation in control panels and distribution gear, speeding retrofits and reducing field labor and enclosure penetrations. The basic feature package offers essential protection at a lower upfront cost while preserving upgrade paths for future needs, supporting capital efficiency. A 15-year warranty reinforces long-term reliability, lowering lifecycle risk and warranty-related maintenance costs. The operating voltage options of 320 L-N, 320 L-G, 320 N-G, and 640 L-L provide versatile protection across different conductor configurations, ensuring compatibility with diverse panel designs and preventing misalignment with existing wiring schemes.

FAQs
Install the SPD080480Y1L using external side mounting as specified for sidemounted versions. Mount the device on the exterior of the distribution equipment or panel with the NEMA 1 flush enclosure, ensuring adequate clearances per the installation manual. Refer to Eaton’s SPD Series sidemounted installation guide and the IM01005031E manual for detailed steps and safety precautions.
An 80 kAIC interrupt rating means the SPD can safely absorb and divert high-energy surges typical in industrial environments, protecting downstream devices such as PLCs, drives, and motors. This rating reduces the likelihood of nuisance tripping and equipment damage during severe transient events common in manufacturing floors and data center utility feeds.
Yes, SPD080480Y1L is UL 1449 listed, which confirms the device meets recognized standards for surge protection performance and safety. This certification provides assurance of protective performance during transient events, supporting compliance with electrical safety programs and reducing risk during audits and inspections.
This SPD is ideal for 277/480V wye (4W+G) distribution in industrial and commercial facilities. It suits control panels, switchgear, and distribution equipment that require sidemounted, external mounting protection with a compact NEMA 1 enclosure, enabling straightforward retrofits and upgrades in existing power architectures.
Eaton backs SPD080480Y1L with a 15-year warranty, providing long-term confidence in protection and reducing lifecycle risk. Maintenance typically centers on periodic inspection of connections and enclosure integrity, with the installation manual offering guidance on inspection intervals and replacement procedures after surge events to maintain optimal protection performance.
