12.0" Height x 12.0" Width x 6.0" Depth (305mm x 305mm x 152mm) Universal Mechanical Dimensions, NEMA Type 1 Standard Rating Protective System Substrate, Type A-12N Solid Single-Piece Sheet Steel Structural Outer Casing Shell, Suffix-12N126 Flat Removable Slip-Joint Screw-Cover Closure Layout, High-Dielectric ANSI 61 Gray Polyester Powder Coat Outer Surface Treatment Finish, Pre-Punched Integrated Conduit Knockout Array Clusters, Rigid Back-Panel Mounting Flange Plugs, Heavy-Duty Vibe-Dampening Wall or Surface Flush-Mount Installation Base, High Stability Facility Infrastructure Junction and Electrical Control Equipment Protection Enclosure Frame | High-performance industrial and commercial-grade heavy-duty raw sheet metal electrical equipment utility enclosure box custom engineered by Hoffman Enclosures (nVent) under foundational part catalog index A-12N126 (commonly tracked across inventory logistics manifests under the shorthand item identifier A12N126). Sharing the exact identical 16-gauge throu-hardened steel unibody chassis shell, ANSI gray powder coating defense matrix, pre-drilled back-mounting hole grids, and slip-joint screw cover closure mechanics as its family sibling, this upscaled model expands the width axis dimension to present a spacious 12" x 12" square mounting footprint template. It functions as an automated long-format signal commoning cabinet or power distribution routing terminal box, providing ample interior panel space to load deep component rails, high-amperage terminal blocks, and auxiliary logic controllers with zero travel lag or structural box bending faults under heavy conduit line loading over immense facility lifetimes. | Industry Exact Equivalents: Hoffman A-12N126, nVent Hoffman A12N126, Hoffman Enclosures A12N126 | Industry Functional Cross-References: Wiegand RSC121206, Hammond 1432L6, Austin Enclosures AB-12126, Cooper B-Line 12126RSC, Nemco 12126 Enclosures
