Eaton 3BR4242L400S Main Lug Loadcenter - UL 67 Listed

Feature: 400 A main lug, three-phase distribution with aluminum bus. Benefit: Delivers heavy-load capacity in a compact footprint, enabling efficient power distribution on the plant floor and reducing the need for oversized upstream gear. Application: Manufacturing lines, machine centers, and large-control panels benefit from reliable, scalable power. Feature: 42 circuits and 42 spaces in a surface-mounted NEMA 1 enclosure. Benefit: Ample capacity supports future expansion and circuit zoning without rehousing, lowering total installed cost. Application: Electrical rooms and service entrances in commercial facilities and industrial spaces. Feature: Aluminum bus and rugged BR family design. Benefit: Lighter weight for easier handling and corrosion resistance, improving installation speed and long-term reliability. Application: New builds and retrofit projects where weight and durability matter. Feature: Factory integrated surge protection and no feed-thru lugs. Benefit: Reduced need for external surge devices and simplified wiring topology, cutting installation time and potential failure points. Application: Critical loads such as drives, PLCs, and motor controls. Feature: NEMA 1 surface enclosure with UL 67 listing and 10-year warranty. Benefit: Compliance assurance, robust protection in indoor environments, and long-term support for maintenance contracts. Application: OEM builds, data centers, and facilities relying on documented warranties. Insight: The 57 in depth and 20 in width footprint aligns with typical wall thickness and service space constraints in retrofit projects, while still accommodating a dense 42-space configuration, a common requirement in modern facility upgrades.
