A12R126HM

Overview

The Hoffman A12R126HM is a horizontal-mount enclosure constructed from steel with an ANSI 61 gray polyester powder-coated finish. It measures 12 inches in length, 12 inches in width, and 6 inches in height (304.8 mm x 304.8 mm x 152.4 mm). Designed for Type 3R compliance, it provides protection against falling rain and sleet. The unit features a flanged design suitable for direct surface mounting without vertical support structures.

Feature Summary

• Horizontal mounting configuration eliminates the need for vertical structural supports
• Type 3R rating ensures protection against environmental elements like rain and sleet
• Flanged design facilitates secure attachment to rooftops or pads

Applications

• Outdoor wiring junction boxes
• Pull box installations on rooftops
• Pad-mounted electrical distribution

Procurement Notes

Verify that the specific order includes the correct mounting hardware and gaskets required for Type 3R sealing integrity. Confirm the finish specification matches the required ANSI 61 gray color code. Ensure the installation site allows for the specified horizontal footprint dimensions of 12 by 12 inches.

Selection Notes

Select this model when vertical mounting space is unavailable or impractical. It serves as a direct alternative to standard vertical enclosures in constrained outdoor environments. Verify that the internal volume accommodates all necessary conductors and connectors for the intended circuit load.

Part Context

This component belongs to the nVent Hoffman Type 3R series, designed specifically for harsh outdoor conditions. It shares the same protective standards as vertical counterparts but utilizes a distinct horizontal form factor. The series emphasizes durability through galvanized steel construction and corrosion-resistant coatings.

Replacement Considerations

Substitute models must maintain identical external dimensions and Type 3R certification. Verify compatibility with existing conduit entries and mounting holes. Ensure the replacement material offers equivalent corrosion resistance for long-term outdoor exposure.
