A16D168

Overview

The A16D168 is a NEMA Type 9 hazardous location enclosure manufactured by Hoffman Enclosures, Inc. Constructed from steel with an ANSI 61 gray polyester powder finish over a pretreated surface, it measures 16.00 inches in length, 16.00 inches in width, and 8.00 inches in depth (406.40mm x 406.40mm x 203.20mm). The unit holds UL and CSA approvals and provides protection suitable for Class II Division 1 and 2 locations.

Feature Summary

• Designed specifically for hazardous locations requiring NEMA Type 9 protection standards
• Constructed from durable steel with a corrosion-resistant ANSI 61 gray polyester powder coating
• Includes UL and CSA approval certifications for industrial safety compliance

Applications

• Class II Division 1 hazardous locations
• Class II Division 2 hazardous locations
• Industrial environments requiring dust ignition-proof protection

Procurement Notes

Verify that the specific application environment strictly aligns with Class II Division 1 or 2 classifications before procurement. Confirm that the required ingress protection level matches the NEMA Type 9 rating. Ensure that the physical dimensions accommodate the intended internal components without compromising the integrity of the enclosure seals. Cross-reference the UL and CSA listing numbers with current certification databases to ensure ongoing compliance with local electrical codes.

Selection Notes

Select this model when the installation site involves combustible particulate fuels such as flour, grain, or coal dust. The steel construction offers robust mechanical protection compared to non-metallic alternatives. Consider the 8-inch depth for adequate component spacing while maintaining a compact footprint. Verify that the ANSI 61 color meets facility-specific visual identification requirements for hazardous zones.
