FAQs
The SPC200480Y1P is designed for 277/480V Wye three-phase systems and features an external side mounting for straightforward retrofit into existing panels. It is UL 1449 listed and housed in a NEMA 4X enclosure, making it suitable for both indoor and outdoor installations in industrial environments. When planning installations, ensure panel space allows for the 7.5 inch depth and the 3.19 inch width while maintaining proper clearance for maintenance.
This device offers a 200 kAIC interrupt rating and a NEMA 4X enclosure, ensuring robust protection against high-energy transients and resistance to dust, water, and corrosion. Its UL 1449 listing confirms compliance with industry surge protection standards. In practice, manufacturers see reduced equipment damage, fewer unscheduled trips, and greater reliability for critical loads such as drives and automation controllers in demanding facilities.
Yes. The SPC200480Y1P carries UL 1449 certification, a foundational requirement for surge protection devices in many NEC-based installations. Its NEMA 4X enclosure further supports compliance in environments with dust, water exposure, or washdowns. For projects with strict regulatory requirements, pairing this SPD with proper panel labeling and protective clearances helps streamline inspection readiness.
Plan for external side mounting to optimize retrofit time and accessibility. Verify the panel has space for a 7.5 in depth and 3.19 in width device, and ensure proper clearances for maintenance. Use appropriate torque on terminals per the Eaton specification, route conductors to minimize inductive loops, and ensure the device is located as close as practical to the protected loads to reduce surge energy reaching critical equipment.
Adopting the SPC200480Y1P typically reduces surge-related equipment damage and downtime, leading to lower repair costs and less production interruption. The 200 kAIC rating provides headroom for future load growth, while the 10-year warranty and UL 1449 compliance contribute to predictable maintenance budgeting. Over time, the result is improved uptime, longer asset life, and a lower total cost of ownership.
