Overview

The Hoffman Enclosures A18R1810HCRQTH is a medium-sized electrical enclosure constructed from galvanized mild steel with an ANSI 61 gray polyester powder-coated finish. It features Type 3R rating, providing protection against falling rain and sleet. The unit measures 18 inches in length, 18 inches in width, and 10 inches in height. It utilizes a screw cover design secured by draw-pull catches and includes galvanized steel lift-off hinges with stainless steel pins.

Feature Summary

• Drip-shield top design with seam-free sides, front, and back for enhanced weather resistance
• Galvanized steel construction with polyester powder painted finish for corrosion protection
• Lift-off hinge mechanism featuring stainless steel pins for durable operation

Applications

• Outdoor control panels
• Power distribution systems
• Industrial drive installations

Procurement Notes

Verify the specific suffix QTH indicates the quarter-turn latch configuration distinct from standard screw covers. Confirm material specifications match project requirements for outdoor exposure. Ensure compatibility with existing mounting infrastructure. Cross-reference catalog numbers to avoid confusion with similar NEMA 3R models lacking the specific latch hardware.

Selection Notes

Select this model when outdoor rain protection is required alongside secure access via quarter-turn latches. The 18x18x10 dimensions provide adequate space for standard industrial components. Verify that the galvanized steel finish meets environmental durability standards for the installation site. Consider accessory availability for cable entries if not included.

Part Context

This component belongs to the Hoffman NEMA 3R enclosure family designed for outdoor use. It shares dimensional similarities with other 18-inch series units but differs in cover fastening mechanisms. The HCR designation typically denotes heavy-duty construction characteristics within the manufacturer's lineup.

Replacement Considerations

Direct substitutes include models with identical NEMA 3R ratings and dimensions. Verify latch type compatibility when replacing standard screw-cover units. Check hinge pin material specifications to ensure equivalent durability.
