High current capacity is provided by an 800 A bus rating, aluminum bussing, and a 10 kAIC interrupt rating. This enables compact distribution of heavy feeders, reducing the number of cabinets required and minimizing wiring complexity in multi‑hundred amp installations. It’s ideal for 3Ø/4W systems in manufacturing lines, processing plants, and commercial facilities where space is at a premium. Durable construction combines galvanized steel and ANSI 61 gray finish with aluminum bussing for corrosion resistance and easy serviceability. The 3R enclosure rating supports indoor or outdoor installation, protecting critical conductors in harsher environments and reducing maintenance cycles. Versatile lug and cable accommodations include line lugs up to #4 - 600 MCM and load lugs sized at 5/16", with room for two 1/0–250 MCM conductor runs. Surface-mount mounting and 6-inch depth simplify installation along walls or mezzanines, while the 85.625-inch width supports multiple feeder connections in a single enclosure. Designed to work with Eaton B-Line series components, the R1126 HDD streamlines procurement, spares handling, and field service. The 4-wire configuration, 6-inch depth and 217 lb weight inform site planning and crane or pallet handling, while UL Listing confirms compliance with safety standards.

FAQs
The cabinet supports line lugs up to #4 - 600 MCM and load lugs sized at 5/16", with capacity for two 1/0–250 MCM cables. Verify lug type and conductor count in your feeder design to ensure compliant termination and reliable current distribution.
R1126 HDD is surface-mount and 6 inches deep with a width of 85.625 inches and height of 22 inches, designed for three-phase four-wire service. Plan mounting on a solid wall, allow adequate clearance for lugs, and align with downstream feeders to minimize elbow and bend losses.
Yes. The unit is UL Listed for electrical safety and carries a NEMA 3R enclosure rating, enabling indoor or outdoor exposure and protection against weather to support reliable year-round operation.
Aluminum bussing provides lower electrical resistance, facilitating efficient current distribution across four conductors. It also contributes to lighter weight relative to all‑steel buswork and offers good thermal performance for continuous operation in demanding environments.
By consolidating feeders into a single rugged cabinet, it reduces panel count and installation time, lowering labor costs. UL/NEMA protections improve safety and reduce field service interruptions, while compatible Eaton B‑Line components streamline spares, procurement, and future expansions.
