Eaton PRL3X3490B00C2 Panelboard - UL 67 & NEMA Compliant
Part Number: PRL3X3490B00C2
Quick Summary
The Eaton Pow-R-Xpress PRL3X panelboard provides compact, high-capacity power distribution for industrial facilities, enabling safe and reliable electrical conditioning in demanding spaces. Faced with limited floor space, awkward panel layouts, and lengthy commissioning, engineers need an interior assembly that ships ready-to-install and reduces on-site complexity. UL 67 listing, NEMA compliance, and copper bus construction underpin safety and longevity, while the three‑phase configuration supports balanced loads and quick fault isolation. With 400 A capacity at 480/277 V and top-feed access, this solution delivers flexible bus routing and scalable expansion, driving lower installation costs and improved maintenance workflows. By combining robust protection with modular design, it aligns with modern low-voltage distribution strategies and helps facilities meet evolving code and performance requirements.
