A4R44

Overview

The Hoffman A4R44 is a commercial-grade steel enclosure with NEMA Type 3R and IP32 ratings, designed for outdoor wiring and junction applications. It features a screw-cover design with a drip-shield top to protect against rain, sleet, and snow. The unit measures 4 inches in height, width, and depth, constructed from galvanized steel with a polyester powder paint finish in ANSI 61 Gray. Available in 12, 14, or 16 gauge thicknesses, it includes knockouts for cable entry sizes ranging from 1/2 to 1 inch.

Feature Summary

• Drip-shield screw cover protects internal components from environmental elements like rain and snow
• Seam-free sides, front, and back construction enhances durability and weather resistance
• Galvanized steel body provides structural integrity for outdoor mounting applications

Applications

• Outdoor wiring protection
• Junction box installation
• Control system housing in exposed environments

Procurement Notes

Verify the specific steel gauge (12, 14, or 16) required for your application, as this affects durability and cost. Confirm that the included knockouts match your cable entry needs. Ensure the NEMA 3R rating aligns with local environmental exposure requirements. Check for any regional compliance certifications necessary for your installation site before finalizing the order.

Selection Notes

Select this model when outdoor weather protection is critical but indoor-rated enclosures are insufficient. The 4x4x4 dimensions suit compact control or junction tasks. Choose based on required mechanical strength; thicker gauges offer higher impact resistance. Verify that the screw-cover mechanism meets security needs, as it lacks integrated padlock provisions compared to other series.

Part Context

This component belongs to the Hoffman A Style Body Enclosure series, characterized by its square profile and commercial-grade construction. It is part of nVent Hoffman's lineup of metal enclosures designed for general-purpose electrical distribution. The A4R44 specifically addresses the need for basic weather protection in standard outdoor settings without requiring complex sealing mechanisms.

Replacement Considerations

Direct substitutes include other NEMA 3R screw-cover enclosures of identical 4x4x4 dimensions from the same manufacturer. Ensure replacement units maintain the same steel gauge and knockout configuration to preserve fitment. Verify that alternative models offer equivalent corrosion resistance through similar galvanization and painting processes.
