Feature → Business Impact → Application: The SPD100480Y2K handles up to 100 kAIC, providing robust transient attenuation that minimizes nuisance outages and equipment stress in motor control centers and panel boards. This translates to increased uptime and longer asset life in manufacturing lines and processing facilities, where surge events can disrupt production. The device’s 277/480V wye rating ensures compatibility with common plant power distribution, enabling straightforward deployment in data centers, machine rooms, and control panels without costly reconfiguration. Enclosed in a rugged NEMA 1 housing and mounted externally on the side, it simplifies retrofits and panel expansion projects, reducing installation time and field labor costs while improving safety margins. The 320/640 voltage operating setpoints give broad surge coverage for 4W+G configurations, supporting diverse loads from drives to sensors and PLCs. With a 15-year warranty and UL 1449 certification, lifecycle costs stay predictable and maintenance planning becomes straightforward, aligning with procurement policies for durable, standards-compliant protection devices. The standard feature package accelerates commissioning and minimizes additional accessory expenses, while compatibility with Eaton SPD series devices supports scalable protection across multiple panels and projects.
