Surge current
80 kA per phase
80 kA per phase surge current protects critical feeders and minimizes busbar damage. This high rating means transient surges from lightning or switching events are diverted before they reach sensitive equipment, reducing the risk of unplanned outages. In 480 Delta (3W+G) systems, the SPD080480D4B provides robust protection for motors, variable frequency drives, and control panels that drive manufacturing lines and process automation. Voltage rating of 480 Delta (3W+G) covers all three phases plus ground conductors, ensuring consistent protection across the switchgear assembly. The result is safer startups, fewer nuisance trips, and reduced field replacements. For facilities building uptime into their service level agreements, this continuity translates to higher productivity, lower maintenance costs, and improved asset performance over the equipment lifecycle. UL 1449 certification provides regulatory confidence and aligns with established electrical protection practices across industrial sectors. The device is designed to work with Power Xpert SPD modules and with switchgear that features a remote display, enabling centralized health monitoring, easier fault tracing, and simplified compliance reporting during audits or inspections. Compact footprint and relatively light weight simplify retrofits and new installs. With a depth of 3.48 in, width of 7.47 in, height of 12.05 in, and a 6.8 lb mass, the SPD080480D4B fits within typical switchgear enclosures without compromising serviceability or future expansion. The compact form factor also reduces installation time by allowing cleaner wiring and better cable management. Compatibility and installation efficiency are reinforced by Power Xpert SPD accessories and remote-display integration. This allows real-time status monitoring, easier preventive maintenance, and faster fault diagnosis. Engineers benefit from clear installation guidelines, fewer compatibility surprises, and a scalable protection approach that supports expanding 480V delta infrastructure across manufacturing lines and data-driven facilities.

FAQs
Follow the Eaton specification guidance to mount the SPD080480D4B in a compatible switchgear enclosure. Ensure correct phase connections for 480 Delta (3W+G), connect to the Power Xpert SPD interface if used, and verify the unit is secured with the remote display wiring intact. Always observe UL 1449 installation practices and perform a post-installation functional test.
80 kA per phase indicates the SPD can safely divert large transient currents on each of the three phases during a surge event. This rating translates to higher protection for motors, drives, and control panels, reducing the likelihood of insulation damage and unplanned equipment outages in demanding industrial environments.
Yes. The device is designed to work with Power Xpert SPD accessories and is suitable for switchgear that includes a remote display. This compatibility enables centralized monitoring, easier fault diagnosis, and streamlined maintenance planning across 480V delta installations.
The SPD080480D4B carries UL 1449 certification, meeting key electrical protection standards commonly required in industrial settings. This certification supports safer operation, easier audits, and alignment with established protection practices for critical equipment and automation systems.
Maintenance is minimal—inspect connections and remote-display status during routine preventive maintenance. By protecting critical drives, PLCs, and control panels, the SPD helps reduce unplanned downtime and part replacements, delivering a favorable return on investment through improved asset life, reduced repair costs, and higher facility uptime.
