Eaton PRL1X3400X42CD Pow-R-Xpress Panelboard - UL 67 Certified
Part Number: PRL1X3400X42CD
Quick Summary
Eaton PRL1X3400X42CD Pow-R-Xpress panelboard distributes 208/120V, three-phase four-wire power for industrial and commercial applications. Facilities struggle with space, limited bus density, and upgrades during capacity expansion; this unit delivers 400A with 42 circuits in a compact footprint, reducing panel count and simplifying wiring. UL 67 listed and NEMA compliant support safety and code assurance, while copper bus minimizes resistance and enhances reliability under peak loads. Designed for quick installation in both retrofit and new-build projects, it enables scalable power distribution with predictable maintenance and lower lifecycle costs. This makes it well-suited for data centers, manufacturing floors, and large office campuses seeking dependable, space-efficient electrical infrastructure.

FAQs
This panelboard occupies a compact footprint while delivering high circuit density—79 in length, 8.5 in width, and 3.75 in height—so planning for alignment with existing enclosures and proper clearance is essential. Its weight of approximately 184.54 lb means multiple installers or suitable lifting equipment may be required during retrofit or initial installation. Ensure downstream wiring paths are sized to support 400A service and that access for maintenance is preserved.
Yes. The PRL1X3400X42CD is designed for 208/120V, three-phase, four-wire applications and is rated for 400A with 42 circuit positions. This makes it well-suited for distributing power to commercial lighting, HVAC controls, and motor loads in mid-size facilities, while providing headroom for expansion and future feeders via the dual SFB provision.
The panelboard is UL 67 listed and NEMA compliant, providing safety assurances and alignment with standard electrical codes. These certifications simplify procurement for code-driven projects and support smoother regulatory inspections, reducing risk during commissioning and operation.
Yes. The design includes dual SFB provision, enabling future feeder additions without replacing the entire panelboard. This lowers lifecycle costs, supports phased capacity growth, and minimizes downtime during upgrades, which is especially beneficial for facilities planning multi-year expansion or modular expansions.
The copper bus provides lower electrical resistance, reducing voltage drop under heavy loads and improving fault current performance. This translates to improved reliability and efficiency, especially for dense circuit layouts and longer feeder runs, making it a durable choice for high-demand environments.
