80 kAIC surge protection rating is engineered to absorb high-energy transients without compromising downstream equipment. This translates to reduced risk of motor insulation damage, control-relay faults, and costly downtime across manufacturing lines. It's ideal for 277/480V wye power networks in panelboards and motor control centers where frequent switching and external surges occur. The 277/480V wye (4W+G) voltage rating supports protection for a wide range of loads, including motors, drives, and controls, ensuring consistent performance across industrial automation environments. A NEMA 1 enclosure with an internal disconnect provides safe, code-compliant installation inside electrical rooms and on exterior surfaces. The external side mounting design simplifies retrofits and new-build integrations, enabling quicker wiring and fewer on-site modifications. The standard feature package includes a surge counter, delivering traceability of surge events for maintenance, audits, and reliability reporting. UL 1449 certification and robust enclosure protection translate to lower lifecycle risk and predictable maintenance costs for facilities teams.

FAQs
When installing SPD080480Y3M externally, ensure the NEMA 1 enclosure is mounted on a clean, accessible surface with adequate clearance for wiring. Use the external side mounting method to simplify wiring runs to L-N, L-G, N-G, and L-L connections. Follow the Eaton installation manual for terminal torque specs, proper conductor sizing, and the protection counter placement for reliable monitoring.
An 80 kAIC interrupt rating means the device can safely absorb high-energy surges without compromising downstream equipment such as motors, drives, and controls. This translates to reduced insulation failure, fewer unplanned outages, and longer equipment life in demanding industrial environments that experience frequent switching and lightning-induced transients.
Yes. The device is designed for external sidemount installation on 277/480V wye systems and fits standard electrical distribution gear, including panelboards and motor control centers. Its NEMA 1 enclosure, internal disconnect option, and surge counter support reliable protection, easy retrofits, and compliant integration with existing protection schemes.
SPD080480Y3M is UL 1449 listed, providing recognized safety and performance compliance for surge protection devices. The NEMA 1 enclosure supports standard indoor installation, while external sidemount configuration aligns with common industrial distribution practices. These certifications simplify procurement, reduce risk during audits, and help maintain electrical system integrity across facilities.
Implementing SPD080480Y3M can lower total cost of ownership by reducing surge-related downtime and equipment wear, extending asset life, and improving maintenance planning with an integrated surge counter. Its compatibility with 277/480V systems and straightforward sidemount installation also lowers retrofit labor costs and accelerates project timelines.
