Eaton R1126 HE Bussed Gutter Cabinets - UL Listed
Part Number: R1126 HE
Quick Summary
The Eaton R1126 HE bussed gutter cabinets deliver rugged surface-mount bus distribution for 800 A systems. Installers often contend with tight spaces, complex lug terminations, and long wiring runs that delay commissioning. This enclosure carries UL Listed certification and a NEMA 3R rating, supporting safe operation in indoor and outdoor environments, plus a 10 kAIC interrupt capacity for surge protection. By integrating standardized line lug sizes (#4 – 600 MCM) and load lug sizes (5/16 inch), along with galvanized steel construction and ANSI 61 gray paint, it reduces field assembly time, simplifies maintenance, and improves long-term reliability.
