Eaton Corporation PRL1 Main Lug Panelboard Assembly

Eaton's Gus Berthold PRL1 Main Lug Panelboard Assembly is a 225 A, 120/208Y, 3-phase, 4-wire panelboard built to distribute electrical power in commercial or light industrial environments. In a main-lug configuration, it feeds downstream circuits via lugs rather than an integrated main breaker, with 42 spaces available for branch-circuit protection devices. This arrangement suits installations where upstream main protection is provided separately and a compact, organized distribution layout is required. The panel supports 120 V line-to-neutral distribution within a 208Y/120 V three-phase system, enabling diverse branch circuits to be managed across its 42-position footprint. The PRL1 model from Eaton offers a modular approach to power distribution, facilitating orderly installation, labeling, and potential circuit expansions within its spacious layout. Typical applications include electrical panels for commercial offices, retail spaces, and light industrial facilities that need a robust, 225 A main-lug distribution solution to manage multiple branch circuits while maintaining a centralized electrical backbone.
