Eaton SPD080480Y2J Surge Protection - UL 1449
Part Number: SPD080480Y2J
Quick Summary
Eaton SPD080480Y2J surge protection device protects electrical gear in motor control centers. Surges from switching events and external disturbances can damage drives and MCCs, leading to costly downtime and component failures. UL 1449 Listed safety certification anchors the product, while it also aligns with IBC 2006, CBC2007, and UBC Zone 4 guidelines to perform reliably in demanding environments. The device’s EMI/RFI filtering reduces electrical noise that can disrupt drives and control logic, and the Form C relay contact plus audible alarm simplify fault signaling. With a 15-year warranty and a compact internal mounting design, this surge protector offers a clear path to improved uptime, lower maintenance costs, and easier integration into existing motor control infrastructure.

FAQs
SPD080480Y2J is designed for 277/480V four‑wire wye systems common in MCCs. It features internal mounting for compact spaces and supports 50/60 Hz operation, ensuring straightforward installation alongside drives and protections in existing motor control centers. Its protection alignment with MCC layouts helps minimize wiring complexity and accelerates commissioning while maintaining reliable transient suppression.
The device delivers 80 kA per phase surge capability with a 200 kAIC short‑circuit rating, plus a nominal discharge current of 20 kA. It protects L‑N, L‑G, L‑L, and N‑G paths and includes EMI/RFI filtering. This combination reduces the likelihood of transformer and drive faults during transients and supports safer, more reliable motor control center performance.
Yes, SPD080480Y2J is UL 1449 Listed, confirming conformity with essential surge protection safety standards. The unit is designed to support industrial installations in line with applicable facility safety practices and, where applicable, aligns with building and electrical standards referenced in IBC and CBC guidelines to aid site compliance and inspection readiness.
Plan for internal mounting within MCC sections and ensure 277/480V, 50/60 Hz compatibility. Verify available space for alarms and wiring, and take advantage of the standard feature package to minimize external accessories. Regularly test the audible alarm and Form C relay during preventive maintenance to verify signaling and diagnostics are functioning as designed.
ROI is driven by reduced downtime, longer motor and drive life, and lower transient-related fault costs. The 15‑year warranty provides long‑term cost certainty, while EMI/RFI filtering improves control reliability. Built‑in diagnostics such as the surge counter and rest button streamline maintenance, shortening service times and lowering spare parts usage.
