A24R186NK

Overview

The Hoffman Enclosures Inc. A24R186NK is a Type 3R drip shield electrical enclosure constructed from mild steel with a galvanized and polyester powder painted finish in ANSI 61 gray. It features an unflanged B-style body design with a single screw cover door. The unit measures 24 inches in height, 18 inches in width, and 6 inches in depth. It is rated NEMA 3R and IP32 for outdoor protection against rain and sleet. The enclosure is designed for wall mounting and includes no knockouts by default.

Feature Summary

• Provides NEMA Type 3R and IP32 protection against falling rain, sleet, and external ice formation for outdoor environments.
• Constructed from 16-gauge mild steel with a durable galvanized and polyester powder-coated finish for corrosion resistance.
• Features an unflanged B-style body configuration with a secure screw-cover door for simplified installation and access.
• Designed as a wiring or junction box suitable for use with or without knockouts in various industrial applications.

Applications

• Outdoor wiring and junction box installations requiring protection from rain and sleet.
• Industrial control panels mounted on exterior walls exposed to weather elements.
• Electrical distribution points in facilities needing NEMA 3R rated enclosures.
• Utility infrastructure housing where IP32 ingress protection is specified.

Procurement Notes

Verify the specific project requirements for NEMA 3R compliance and physical dimensions (24x18x6 inches) before ordering. Confirm that the absence of pre-drilled knockouts aligns with the intended cable entry strategy, as field drilling may be necessary. Ensure the wall-mounting surface can support the weight of the steel enclosure when loaded. Check for any local environmental codes regarding the gray polyester powder paint finish in corrosive atmospheres.

Selection Notes

Select this model when a compact, unflanged enclosure is required for outdoor wall mounting. The 16-gauge steel construction offers robust mechanical protection compared to thinner alternatives. Consider the lack of knockouts if custom entry points are preferred over standard factory options. This unit is appropriate for applications where Type 3R weather protection is sufficient, rather than higher ratings like Type 4X for washdown environments.

Part Context

This component belongs to the Hoffman B-Style Body Enclosure series, which is characterized by its unflanged design and screw-cover mechanism. The A24R186NK specifically represents the 24-inch height variant within the 18-inch width family. It is part of nVent Hoffman's standard line of steel enclosures designed for general-purpose industrial and commercial electrical protection.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Users should verify compatibility with existing mounting hardware and conduit entries. Alternative models may require re-evaluation of dimensional constraints and ingress protection ratings to ensure equivalent performance.
