Surge current
80 kA per phase
The SPD080480Y4A delivers 80 kA per phase surge capability, a key feature that directly reduces the risk of transient events damaging critical loads. This higher protection level translates to fewer unplanned outages and lower repair costs, especially in manufacturing lines and data-center environments where uptime is non-negotiable. It is designed for 277/480 V Wye configurations (4W+G), enabling straightforward integration with common industrial power distribution without reconfiguring existing panels. The voltage rating ensures compatibility with standard equipment and minimizes misapplication, supporting safer commissioning and faster project rollout. UL 1449 certification provides a validated safety baseline, helping facilities meet regulatory expectations while avoiding delays in approvals. As part of Eaton’s Power Xpert SPD ecosystem, the device works seamlessly with panel-mounted protection strategies and monitoring options, enhancing asset intelligence. Direct bus mounting on panel boards PRL1a, 2a, 3a, 3e reduces wiring complexity and supports modular expandability for future capacity. Installation efficiency, combined with robust surge performance, leads to measurable uptime gains and lower total cost of ownership over the system lifecycle.
