Eaton R1122 HCC Bussed Gutter Cabinets - UL Listed
Part Number: R1122 HCC
Quick Summary
The Eaton B-Line series bussed gutter and termination cabinets provide rugged, code-compliant power distribution for industrial enclosures. In compact facilities, wiring and lug sizing between main and load lugs can become a source of misfit and downtime if parts don’t align. UL Listed safety certification and NEMA 3R enclosure protection support reliable operation in indoor spaces and sheltered outdoor environments. For panel builders and system integrators, this cabinet pairs with the B-Line gutter systems and delivers surface-mount convenience, a 400 A bus, and a 10 kAIC interrupt rating to accelerate commissioning, ensure compliance, and reduce field rework. The 5-position design, load/line lug options (#4 - 600 MCM, 5/16" lug mounting holes) optimize wiring layout.

Feature: 400 A bus rating provides robust power distribution with reduced subpanel count and simplified panel design. Benefit: Improves system efficiency and lowers upfront hardware costs by handling higher load in a single enclosure, reducing cabinet sprawl. Application: Ideal for mid-to-large industrial control panels and process skids. Feature: 3R enclosure rated cabinet with 10 kAIC interrupt rating enhances safety and short-circuit protection. Benefit: Higher fault tolerance minimizes downtime and protects downstream equipment. Application: Suitable for motor control centers and outdoor feed cabinets in protected environments. Feature: Surface-mount mounting and 6 in depth with 28.375 in width enable flexible installation in constrained spaces. Benefit: Easier retrofit and new builds where wall space is at a premium, reducing installation time. Application: Metering rooms, electrical closets, and equipment pads. Feature: Line lug size #4 - 600 MCM and load lug size 5/16" with (2) 1/0-250 MCM cables capacity. Benefit: Streamlines wiring topology, supports pre-terminated bundles, and minimizes field termination errors. Application: Large-diameter feeders and multi-conductor bus connections in 3Ø/4W systems. Feature: Galvanized steel construction with ANSI 61 gray paint and UL Listed certification. Benefit: Durable, corrosion-resistant enclosure with verified safety standards, reducing maintenance and replacement costs. Application: Harsh or semi-exposed industrial environments requiring dependable enclosure integrity.
