High surge capability is delivered by a true 100 kAIC interrupt rating, allowing the SPD to clamp fast transients before they reach critical loads. That protection translates to lower incident energy delivered to drives, PLCs, and control electronics, reducing component burnouts and unplanned downtime. In manufacturing lines and automated test rigs, this means fewer unplanned stops during switching or grid disturbances. Engineers can spec the SPD with confidence knowing it shares common protection profiles with other Eaton devices, simplifying maintenance planning. Designed for 277/480V wye systems with a four-wire plus ground configuration, SPD100480Y1O aligns with typical power distribution schemes in industrial facilities. This compatibility minimizes field rework and reduces the need for voltage conversion or transformer work during retrofits. Operators benefit from consistent protection across feeders feeding motors, contactors, and drives. The enclosure is NEMA 4X, enabling installation in damp or outdoor environments, while external side mounting simplifies field retrofits alongside existing panels. This combination reduces installation time, minimizes service interruptions, and supports code-compliant outdoor deployments. The basic feature package provides essential surge protection upfront, allowing project teams to meet protection requirements without premium add-ons. For projects with strict budgets, this supports fast procurement cycles and simpler commissioning. Users can later augment protection by applying additional accessories as system needs evolve. The compact footprint and measured 9.5 in length, 5.4 in width, and 3.45 in height enable installation in crowded switchboards and electrical rooms. Lightweight 3.5 lb design reduces handling and shipping costs during deployment. External mounting also improves serviceability, so technicians can access wiring and test points without removing the device. A 15-year warranty along with UL 1449 certification provides long-term risk mitigation and predictable maintenance budgeting. Comprehensive product literature and installation manuals support fast commissioning and ongoing reliability.

FAQs
SPD100480Y1O uses external side mounting to simplify retrofit work alongside existing switchgear and side-mounted panels. Plan for adequate clearance and wiring access, and reference the installation manual for wiring terminations and torque specs. The rugged NEMA 4X enclosure supports outdoor or damp locations, improving field serviceability and reducing stoppages during upgrades.
The device provides a 100 kAIC interrupt rating with protection across 320 V line-to-neutral, line-to-ground, and neutral-to-ground paths, plus 640 V line-to-line. This performance clamps transient spikes before they reach motors, drives, and controls, enhancing uptime and reducing failure rates in harsh industrial environments.
Yes. The unit comes in a NEMA 4X enclosure rated for harsh indoor and outdoor conditions, including dust and moisture exposure. Its external side mounting is designed for easy integration with exterior distribution equipment, enabling reliable protection without compromising cabinet integrity or aesthetics.
The SPD100480Y1O is UL 1449 certified, ensuring compliance with recognized safety standards for surge protective devices. It carries a 15-year warranty, providing long-term protection and budget predictability for mission-critical installations and ongoing maintenance planning.
By reducing surge-related damage and downtime, the SPD100480Y1O lowers maintenance costs and extends asset life for feeders, motors, and drives. Its robust 100 kAIC protection, easy retrofit, and long warranty enable quicker commissioning, lower field labor, and predictable budgeting, delivering meaningful ROI in manufacturing, data centers, and critical electrical infrastructure.
