Eaton PRL2X3400X42AS Panelboard - UL 67 Certification
Part Number: PRL2X3400X42AS
Quick Summary
Eaton PRL2X3400X42AS Panelboard is a Pow-R-Xpress interior solution for 480/277V, 3P 4W distribution. This addresses the common pain point of bulky, slow-to-install power panels that struggle to fit tight spaces and tight project timelines. With UL 67 certification and NEMA-compliant design, plus an aluminum bus for durability, the unit delivers safety and long-term reliability. The panelboard supports scalable, space-efficient distribution, making it attractive for industrial facilities and commercial buildings alike. Secondary considerations include its 42 circuits and 400A rating, which align with mid-range power needs while enabling straightforward expansion and maintenance.

Eaton Specification Sheet - PRL2X3400X42AS
Feature → Business Impact → Application: The PRL2X3400X42AS delivers 400A capacity in a 42-circuit interior panelboard, enabling high-demand feeds without proliferating enclosure footprints. This reduces footprint, simplifies labeling, and lowers installation time, benefiting manufacturing lines and data centers that require reliable distribution with room to grow. Feature → Business Impact → Application: Aluminum bus construction reduces weight and improves corrosion resistance, making field wiring and servicing easier while lowering ballast load on support structures. This translates into faster commissioning and safer handling on the plant floor, ideal for retrofit projects and new builds with tight schedules. Feature → Business Impact → Application: UL 67 certification and NEMA compliance provide regulatory assurance and fault tolerance, decreasing risk during audits and occupancy. This is crucial for healthcare, education, and critical industrial environments where downtime carries significant cost. Feature → Business Impact → Application: 480/277V, 3P 4W configuration matches common facility service standards, enabling plug-and-play integration with existing panels and switchgear. This minimizes engineering effort and accelerates project timelines for commercial buildings and mixed-use developments. Feature → Business Impact → Application: The Pow-R-Xpress interior design supports rapid wiring and modular expansion, lowering total cost of ownership over the equipment lifecycle. This benefits OEMs and maintenance teams seeking predictable maintenance schedules and scalable power distribution in automotive, manufacturing, and data-intensive facilities.
