Eaton PRL2X3400X42C1 Pow-R-Xpress Panelboard - UL 67

Power capacity and circuit density drive panelboard selection. The PRL2X3400X42C1 delivers 400A with 42 total circuits in a single interior unit, enabling compact, scalable distribution for mid- to large-load applications. This consolidation reduces footprint on crowded clean rooms or machine areas, accelerating wiring layouts and simplifying procurement for OEMs and integrators. In manufacturing floors and data centers, a high-density interior panelboard like this supports critical feeders while leaving headroom for future expansion. This design also helps reduce derangements in busy facilities by preserving aisle space and simplifying maintenance access. Copper bus construction reduces contact resistance, improves voltage regulation, and lowers heat rise under peak loads. The result is improved efficiency and clearer thermal margins. For projects requiring tight protection coordination and reduced maintenance cycles, this feature translates into lower operating costs and fewer field adjustments. Thermal margins also help prevent nuisance trips and extend service intervals. Operational versatility comes from 120/208V, 3-phase 4-wire input, making it compatible with common industrial power sources. The long interior length of 61 in allows more feeders and breakers without compromising service access, while the 42-circuit capacity supports planned growth and phase balancing. This interior panelboard is designed for straightforward field wiring and neat, labeled installations that meet traceability standards. Field wiring remains clean thanks to the interior layout that minimizes wire wrap and tangles. Safety and compliance are reinforced by UL 67 listing and NEMA compliance, giving owners confidence for code-conscious projects and OEM integrations. The copper bus and interior-only design simplify labeling, testing, and preventive maintenance scheduling, reducing downtime during routine service. UL/CSA labeling and documentation streamline audits. Ease of installation and procurement are addressed through documented specifications and Eaton's Pow-R-Xpress stock program resources, enabling faster lead times and consistent performance across sites. Engineers benefit from predictable electrical characteristics, standardized interfaces, and a proven supply chain that supports uptime targets and total cost of ownership. The program brochures and datasheets provide installation checklists to speed commissioning.
