Surge current
80 kA per phase
80 kA per phase surge current provides strong protection against high-energy transients, reducing the likelihood of insulation damage and costly downtime. This capability translates to fewer unplanned outages in heavy industry, improving line reliability and extending drive lifetimes on motor and switchgear. The device’s 480 Delta (3W+G) rating ensures compatibility with typical industrial power distribution, enabling quick retirement of risk-prone equipment and smoother commissioning of new lines. The NEMA 1 flush enclosure supports clean, space-efficient installations inside standard electrical panels, allowing rapid retrofits and safer servicing in crowded environments. Compatibility with Power Xpert SPD enables centralized monitoring and coordination across Eaton’s protection network, simplifying maintenance planning and improving overall site reliability. With UL 1449 listing, users gain confidence in compliance and safety, while the robust enclosure and proven performance address common objections about retrofit feasibility and panel integration. In practice, this means lower total cost of ownership through improved protection uptime and predictable maintenance budgets in manufacturing facilities and process lines. The SPD080480D4L also benefits from Eaton’s engineering rigor, offering a field-ready solution that aligns with existing protection schemes and future upgrades to smarter protection architectures.

FAQs
Install SPD080480D4L inside a NEMA 1 flush enclosure mounted in a 480V delta panel. Connect the L1, L2, and L3 lines and the protective earth/ground per Eaton installation guidelines, ensuring proper conductor sizing and clearance. Use compatible Power Xpert SPD accessories for monitoring and coordination, and comply with local electrical codes during retrofit or new installations.
80 kA per phase indicates the device can safely absorb high-energy transient pulses on each phase before reaching its limit. This rating translates to stronger protection for motors, drives, and other high-energy equipment, reducing insulation stress and the risk of insulation failure during lightning-induced or switching transients, thereby extending equipment life and reducing outages.
Yes. The 480V delta rating and three-phase protection make it suitable for industrial manufacturing lines and data-center infrastructure using 480V power. Its NEMA 1 enclosure and UL 1449 listing support rugged panel installations, while Power Xpert SPD compatibility enables centralized monitoring, helping data centers and factories coordinate protective measures across multiple racks and panels.
SPD080480D4L is UL 1449 listed, ensuring compliance with recognized safety standards for surge protective devices. It uses a NEMA 1 flush enclosure for robust indoor mounting and is designed to integrate with Eaton’s Power Xpert SPD family, facilitating coordinated protection and easier panel integration.
The device reduces unplanned downtime by protecting critical loads from transient overvoltages, potentially extending the life of motor drives and switches. With reliable protection and centralized monitoring via Power Xpert SPD, maintenance planning becomes more predictable, resulting in lower total cost of ownership and improved return on investment for industrial facilities.
