Feature: 800 A bus rating and 10 kAIC interrupt capability. Business impact: Enables safe handling of higher fault currents and supports scalable feeder designs, reducing upstream equipment stress and potential downtime. Application: Ideal for medium-to-large power distribution in commercial, mechanical, and light-industrial facilities. Feature: NEMA 3R enclosure rating with galvanneal galvanized steel and ANSI 61 gray paint. Business impact: Delivers corrosion resistance and outdoor-ready or harsh-indoor durability, lowering maintenance costs while meeting indoor/outdoor codes. Application: Suitable for mechanical rooms, corridors, and semi-exposed installations often found in data centers and campuses. Feature: Surface-mount mounting with a 6 in depth, 48 in width, and 22 in height. Business impact: Simplifies retrofits and new builds by reducing install footprint and wall clearance requirements, speeding commissioning. Application: Preferred where wall space is constrained yet large bus cabinets are needed. Feature: Line lug size #4 - 600 MCM and load lug size 5/16". Business impact: Streamlines field wiring with heavy-gauge lugs, lowering termination time and risk of improper lug connections. Application: Fits high-capacity feeders and bus connections for 1Ø/3W systems. Feature: 3 positions, (2) 1/0-250 MCM cable entries, 1Ø/3W configuration. Business impact: Enhances cable routing flexibility and fault-clearing efficiency, reducing rework during installation. Application: Meets typical commercial lighting, HVAC, and utility feeder needs. Feature: Surface mount installation and standard B-Line compatibility. Business impact: Accelerates deployment across multiple sites with familiar Eaton infrastructure, reducing training and procurement complexity. Application: Widely adoptable in new builds and upgrades where standardized bus gutter solutions are required.

FAQs
The R1048 HE uses surface mounting, designed to be fast and straightforward to install. It accommodates 1Ø/3W service configurations with three conductors, and it supports sizable line and load lugs (line lug size: #4 - 600 MCM; load lug size: 5/16 inch). This combination simplifies routing of feeders and enables clean, code-compliant terminations in compact spaces.
The cabinet is rated for an 800 A bus and a 10 kAIC interrupt rating, enabling safe handling of high fault currents and enabling scalable feeder configurations. These ratings support robust protection coordination for mid-size commercial and light-industrial installations while aligning with common utility feeder requirements.
Yes, the R1048 HE is UL Listed and features a NEMA 3R enclosure rating, providing weather resistance and reliability for indoor and selected outdoor environments. This combination helps ensure compliance with safety standards while offering durable performance in challenging spaces.
The enclosure measures 48 inches wide, 22 inches high, and 6 inches deep, with an approximate weight of 127 pounds. These dimensions help with wall clearance, structural support planning, and ensuring adequate access for installation and future maintenance in mechanical and electrical rooms.
Best suited for commercial and light-industrial power distribution, the R1048 HE supports 800 A feeders with 10 kAIC fault capability in surface-mount installations. Ideal use cases include mechanical rooms, utility corridors, data centers, and other spaces requiring standardized bussed gutter and termination cabinets for reliable feeder termination and rapid deployment.
