FAQs
SPC050480N7P is designed for external side mounting, which streamlines integration with existing enclosures. Before installation, confirm available space on the panel exterior, ensure proper clearance for the 5.5 in depth and 3.19 in width, and verify wiring routes to minimize circuit interference. The unit supports standard single-phase configurations and can be retrofitted into many Eaton-ready systems without major cabinet modifications.
The device provides a 50 kA surge rating at 488 V, delivering robust transient protection for sensitive electronics in industrial environments. This combination helps clamp voltage spikes on 480 V-class systems, reducing equipment stress on controllers, motors, and sensors. The rating is suitable for modern control panels that demand reliable surge suppression without compromising normal operation.
Yes. The SPC050480N7P is specified as single-phase and comes in a rugged NEMA 4X enclosure, making it well-suited for harsh indoor and outdoor environments. This configuration supports typical control panels, MCCs, and weather-exposed installations where dust, moisture, and incidental splashes are concerns, while maintaining ongoing protection and signaling performance.
The primary certification listed is UL 1449, confirming safety and performance for surge protection devices. This certification helps ensure compliance with electrical safety standards in industrial settings. While other certifications aren’t specified in the data, the UL 1449 designation is a critical benchmark for meeting regulatory expectations in North American facilities.
Maintenance is typically minimal for a properly selected SPD; routine inspections and connection checks during scheduled PMs are sufficient. The ROI stems from reduced downtime, longer life for drives and relays, and lower emergency repair costs. Coupled with a 10-year warranty and UL 1449 certification, the SPC050480N7P offers predictable total cost of ownership and improved plant reliability.
