Quick Summary

Eaton PRL1X1400B42A Pow-R-Xpress panelboard is a compact interior power distribution solution for 120/240V systems used in commercial and light-industrial spaces. Upgrading legacy panels often means wrestling with cramped layouts, complex wiring, and long downtime; this unit's generous footprint consolidation helps minimize installation risk and field errors. UL 67 listing confirms safe operation in interior panels and the aluminum bus offers durable, corrosion-resistant performance under demanding conditions. With a 400A capacity across 42 circuits and seamless compatibility with Eaton's stocking ecosystem, it supports efficient procurement and rapid restoration after outages. In practice, engineers gain predictable commissioning timelines, improved maintenance planning, and lower total cost of ownership through standardized components and easy cross-compatibility with common breakers.
