Hoffman A12R126NK NEMA 3R Enclosure Galvanized Steel 12x12x6 in

Description

Product Overview

The Hoffman A12R126NK NEMA 3R enclosure is engineered to deliver unmatched protection for electrical components in demanding outdoor settings. Constructed from 16‑gauge galvanized steel, the enclosure resists corrosion, impacts, and the harsh elements that can compromise lesser housings. Its dimensions of 12.00 x 12.00 x 6.00 inches provide ample interior volume for a wide range of conduit, wiring, and junction box configurations while maintaining a compact footprint that fits easily into crowded panels or equipment racks. The enclosure carries UL‑listed (UL 50, 50E) and cUL/CSA certifications, confirming compliance with rigorous safety standards and assuring users that the product meets or exceeds industry expectations for durability, ingress protection (IP32), and fire resistance. The NEMA Type 3R rating specifically addresses protection against rain, sleet, and external ice formation, making this enclosure an ideal choice for outdoor installations, utility poles, and harsh industrial environments where moisture and debris are constant concerns.

Usage

Designed for versatility, the Hoffman enclosure can be deployed in a multitude of real‑world scenarios. Electrical contractors frequently select this enclosure for outdoor conduit terminations, street lighting control panels, and remote sensor housings where exposure to weather is inevitable. Its robust steel construction also makes it suitable for indoor applications that demand extra protection, such as chemical processing plants, manufacturing floors, and heavy‑duty machinery enclosures. The enclosure can be used with or without pre‑drilled knockouts, allowing users to customize the number and size of openings to accommodate specific cable entries, conduit sizes, or ventilation requirements. Because the enclosure meets NEMA Type 3R standards, it can be safely mounted on exterior walls, poles, or brackets without the need for additional weatherproofing measures. The product’s moderate weight of approximately 12.08 pounds strikes a balance between sturdiness and ease of handling, enabling technicians to install it quickly using standard tools while still providing a secure, tamper‑resistant enclosure for critical electrical infrastructure.
