A12R84

Overview

The Hoffman Enclosures A12R84 is a commercial-grade screw-cover enclosure constructed from galvanized steel with a polyester powder-coated finish in ANSI 61 gray. It measures 12 inches in height, 8 inches in width, and 4 inches in depth. The unit features a slip-on removable cover secured by plated steel screws along the bottom edge and includes embossed mounting holes on the rear panel for wall installation. It is rated NEMA 3R and IP32, providing protection against falling water and solid objects larger than 1mm. The enclosure is designed for outdoor applications requiring resistance to rain and sleet.

Feature Summary

• Constructed from galvanized steel with a durable polyester powder-coated finish
• Features a slip-on removable cover fastened with plated steel screws
• Includes embossed mounting holes on the back for secure wall installation
• Rated NEMA 3R and IP32 for outdoor weather protection

Applications

• Outdoor wiring or junction box installations
• Protection of control systems in environments exposed to rain and sleet
• Commercial electrical component housing
• Wall-mounted equipment protection

Procurement Notes

Verify that the specific order matches the A12R84 part number to ensure correct dimensions (12x8x4 inches) and material specifications. Confirm the requirement for NEMA 3R rating aligns with the intended outdoor application. Check for included knockouts if cable entry points are needed. Ensure compatibility with existing mounting infrastructure due to the fixed embossed hole pattern on the back panel.

Selection Notes

Select this model when a compact, weather-resistant enclosure is required for outdoor commercial use. The NEMA 3R rating makes it suitable for protecting against rain and sleet but not submersion. Consider the internal volume of 12x8x4 inches for component fitment. The screw-cover design offers easier access compared to hinged doors while maintaining environmental sealing. Galvanized steel provides corrosion resistance for harsh outdoor conditions.

Part Context

This product belongs to the nVent Hoffman commercial enclosure line, specifically the A Style Body series. These enclosures are widely used in industrial and commercial settings for general-purpose electrical protection. The A12R84 variant represents a standard size within this family, balancing compact footprint with adequate internal space for common control devices. It is distinct from heavy-duty industrial models by its commercial-grade construction and specific NEMA 3R rating.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When replacing, ensure the new enclosure matches the exact external dimensions (12x8x4 inches) and mounting hole patterns. Verify that the replacement meets or exceeds the NEMA 3R/IP32 rating for the intended outdoor environment. Material compatibility (galvanized steel) should be maintained for similar corrosion resistance.
