HOFFMAN A8R84NK Electrical Enclosure

The HOFFMAN A8R84NK is a carbon steel electrical enclosure designed for wall-mounted installations requiring environmental protection. It suits installers and facility managers housing wiring or components in indoor or sheltered outdoor locations. The NEMA Type 3R and IP32 ratings confirm resistance to falling dirt, rain, sleet and external ice formation. It is not intended for applications demanding submersion protection or higher-pressure washdown ratings.

Capacity and Headroom

The enclosure provides an 8-inch by 8-inch interior footprint with a 4-inch depth, offering volume for terminal blocks, relays or small junction assemblies. The 12/14/16 gauge steel construction delivers structural rigidity for standard component loads and conduit entries. Available space diminishes quickly when mounting DIN rails, larger transformers or dense cable bundles requiring generous bend radii. Installers planning extensive future expansion should evaluate internal layout before committing.

Thermals, Noise and Power Draw

As a passive metal enclosure, the unit generates no operational noise and draws no electrical power itself. The galvanized carbon steel body dissipates internal heat through natural convection across its surface area. Thermal performance depends entirely on the heat output of installed devices, ambient temperature and ventilation provisions added by the installer. No active cooling features are integrated, so high-wattage loads may require vented covers or external airflow management.
