Eaton 34242EFN BR Main Lug Loadcenter - UL 50/UL 67
Part Number: 34242EFN
Quick Summary
The Eaton BR main lug loadcenter distributes power safely to large circuits in commercial and light industrial panels. Engineers often struggle with matching amperage ratings, enclosure types, and wire sizing for reliable performance. UL 50 and UL 67 listings ensure safe enclosure performance, while NEMA 1 construction supports indoor dry environments. With a 600 A rating, 42 circuits/spaces, and a galvanized steel enclosure, it accelerates installations and supports expansion in industrial control rooms for long-term reliability. The included cover and door lock enhance security and serviceability, while a 10-year warranty helps protect total cost of ownership of the system.
