Eaton R1123 HC Bussed gutter cabinets - UL Listed
Part Number: R1123 HC
Quick Summary
Eaton R1123 HC bussed gutter cabinets serve as high-current termination enclosures for switchgear and industrial control panels. This solution addresses the common challenge of compact space management and precise lug termination by delivering a rugged, pre-wired platform. UL Listed and NEMA 3R-rated construction provide reliable environmental protection, while galvanised steel with ANSI 61 gray finish resists corrosion in factory floors and outdoor locations. With a 400 A bus rating and 10 kAIC interrupt rating, the unit supports scalable power distribution and improved fault handling. Its 6 in depth, 13 in height, and 42.75 in width offer a balanced footprint for modern control rooms, and the 5/16" load lug and #4 - 600 MCM line lug capacity simplifies wiring and reduces field termination time.

FAQs
Yes. The R1123 HC follows Eaton B-Line design conventions for bussed gutters, supporting standard line lug size of #4 - 600 MCM and load lug size of 5/16", with surface-mount mounting. This enables straightforward retrofits and predictable field terminations, reducing commissioning time and the risk of mis-wiring during installs.
Key specs are a 400 A bus rating and a 10 kAIC interrupt rating, along with UL Listed protection and a NEMA 3R enclosure. These ratings confirm safe fault-current handling, reliable power distribution, and environmental protection suitable for indoor and outdoor industrial applications.
Ideal for switchgear terminations, motor control centers, and panelboard terminations in manufacturing, water treatment, and data-center support rooms. Its 6 in depth, 13 in height, and 42.75 in width provide a compact footprint while supporting 3-wire configurations and multiple feeder connections.
The R1123 HC is UL Listed and features a NEMA 3R enclosure rating for weather resistance. The finish is ANSI 61 gray paint on galvanized steel, offering corrosion resistance suitable for industrial environments. These certifications help ensure compliance with safety and reliability standards in demanding facilities.
Maintenance is minimized by a robust galvanized steel construction and a corrosion-resistant finish, reducing repaint cycles and corrosion concerns. ROI is enhanced through faster installation, reduced field terminations, and reliable fault protection that lowers downtime and service costs over the cabinet’s life cycle.
