Eaton PRL4B Main Lug Panelboard

The Eaton PRL4B Pow-R-Line MLO Main Lug Panelboard is a distribution panel designed for 480Y 277V operation with an 800A rating in a 3Ph 4W, three-phase four-wire configuration. Identified by the PRL4B model, it belongs to Eaton’s Pow-R-Line family and is configured as a Main Lug Panelboard (MLO), meaning it provides lug-based connections for distributing power to downstream circuits within a multi‑circuit installation. With a 480Y 277V input and an 800A capacity, this panelboard is built to handle substantial electrical loads across multiple branches in systems that utilize three-phase, four-wire power, aligning with common industrial and commercial distribution standards. The combination of voltage, current rating, and the 3Ph 4W arrangement positions the PRL4B as a robust option for projects requiring a reliable, high-capacity panelboard from Eaton.
