Pow-R-Line Xpert family overview
400A amperage rating ensures the panelboard can feed multiple loads from feeders to subcircuits without overcrowding, reducing mid-project upgrades. This three-phase panelboard is suited for demanding industrial loads and high-density commercial applications, delivering consistent performance under peak demand. Copper bus construction provides low impedance and durable current paths, improving voltage regulation and fault clearance. The combination of copper bus and UL/NEMA compliance gives facilities teams confidence in long-term reliability and safety during routine maintenance or expansion. Top-feed configuration simplifies incoming feeders and wiring routes, speeding installation in retrofit projects and new builds. Built for compatibility with MCB PD3 modules and a 30-circuit subfeed layout, it supports scalable expansion without rework. Interior PRL3X design optimizes space with a long 78 inch footprint while maintaining accessible maintenance access. The 208/120V, 3P system support enables straightforward motor starter and lighting branch connections in mixed loads. Pow-R-Xpress stocking program compatibility means faster procurement, reducing downtime and project costs. The panel's standardized mounting and modular interior design streamline service and spare parts planning across Eaton’s ecosystem.

FAQs
The PRL3X3490B30C1S is a 208/120V, three-phase panelboard designed for top-feed installations and interior configurations. It supports MCB PD3 modules and a 30-circuit subfeed layout, making it suitable for retrofit projects or new builds where existing electrical rooms must accommodate a compact, scalable distribution solution without extensive rewiring.
Key specs include a 400A amperage rating, copper bus material, dimensions of 78 inches in length, 12 inches in width, and 5.75 inches in height, weight around 120 pounds, 208/120V operation, three-phase, UL 67 listing, and NEMA compliance. It supports up to 30 circuits with a top-feed interior configuration, ideal for dense load centers.
Yes. The PRL3X3490B30C1S panelboard is UL 67 listed and NEMA compliant, ensuring safety, mechanical reliability, and code conformance in commercial and industrial environments. These certifications support compliance during inspections and reduce risk for mission-critical applications such as manufacturing lines and data-center peripheral rooms.
This three-phase, 400A interior panelboard is ideal for main distribution or subfeed applications in industrial facilities and large commercial buildings. Its space-efficient 78 x 12 x 5.75 in footprint and copper bus design suit load centers, machine cells, lighting and motor control zones, with easy integration into Pow-R-Xpress stocking workflows.
Maintainability is enhanced by a standardized interior design and compatibility with PD3 modules, reducing spare parts diversity. The Pow-R-Xpress stocking program shortens lead times, lowering downtime during expansions or service needs. Routine inspection for connections and bus bars, along with timely replacement of worn subfeed components, helps sustain peak performance and extend service life.
