Pow-R-Line Xpert family overview
Feature: High amperage capability and 480/277V three-phase operation → Business Impact: Supports heavy-load distribution and future growth with a single residential or light-industrial feeder, minimizing the need for mid-project upgrades. Application: Ideal for commercial spaces and light manufacturing where reliable 400A capacity is required. The long-term energy management benefits come from consistent current delivery and reduced thermal stress on conductors. Feature: Copper bus material → Business Impact: Improves conductivity, durability, and longevity, reducing voltage drop and maintenance costs over time. Application: Best suited for demanding environments with frequent switching and higher fault-impedance tolerance, ensuring consistent performance across cycles. Feature: Top feed design → Business Impact: Eases installation and field wiring, shortening project timelines and reducing labor costs. Application: Retrofit projects and new builds where accessible wiring from the top is preferred for streamlined conduit routing. Feature: Compliance and protection (UL 67, NEMA 1) → Business Impact: Ensures code compliance and enclosure protection for indoor use, lowering risk and inspection durations. Application: Corporate facilities, data centers, and production floors that require proven safety standards. Feature: Compact footprint (61 in L, 12 in W, 3.75 in H) and weight (100 lb) → Business Impact: Maximizes space efficiency in crowded service areas while maintaining robust electrical capacity. Application: Retrofit and new-build environments with restricted mounting envelope. Feature: Compatibility with Pow-R-Xpress lineup and standard MCB configurations → Business Impact: Facilitates quick integration and future upgrades with familiar components, reducing procurement complexity. Application: Teams upgrading legacy panels or expanding capacity within the Pow-R-Xpress ecosystem.

FAQs
The PRL3X3472B00C2 panelboard is designed for top-feed installation and supports 480/277V three-phase, four-wire systems. For installation, ensure proper mounting, connect feeders to the interior assembly, and fit Eaton MCBs compatible with the Pow-R-Xpress interior. Verify UL 67 and NEMA 1 adherence during commissioning to confirm safe, code-compliant operation.
This panelboard carries a 400A amperage rating with a 400A bus rating, enabling substantial load distribution while maintaining manageable heat and voltage drop. For facilities with peak demand charges, the 400A capacity supports scalable distributions and efficient feeder design without oversized starters, improving overall energy management and reducing wiring complexity.
Yes. With a 61 inch length, 12 inch width, 3.75 inch height footprint and a 100 lb weight, the interior panelboard fits constrained spaces common in dense industrial and commercial settings. Its three-phase 480/277V capability and copper bus support reliable, heavy-duty distribution, making it suitable for data centers, manufacturing lines, and other high-demand environments.
The unit is UL 67 certified and features a NEMA 1 enclosure, with the product listed as NEMA Compliant. These certifications confirm indoor-use suitability, protection against limited dust and vertical surfaces, and alignment with established safety standards, reducing inspection delays and ensuring regulatory compliance for commercial installations.
The Pow-R-Xpress interior panelboard uses copper bus for durable, low-resistance connections, supporting long-term efficiency and reduced thermal stress. Its modular interior design simplifies maintenance and future expansion, which lowers lifecycle costs and improves uptime, delivering a favorable return on investment for facilities planning capacity upgrades.
