The A16D128 is a hazardous location enclosure manufactured by Hoffman Enclosures, Inc. It measures 16.00 inches in length, 12.00 inches in width, and 8.00 inches in depth (406.40mm x 304.80mm x 203.20mm). Constructed from steel with a gray polyester powder finish, it features a hinged door design. The unit holds NEMA Type 9 and IP60 ratings, specifically engineered for Class II Division 1 and 2 locations as defined by NEC 500.
Verify that the specific installation environment matches Class II Division 1 or 2 requirements before procurement. Confirm that the NEMA Type 9 rating aligns with local electrical codes regarding combustible dust protection. Ensure physical dimensions accommodate the intended equipment layout within the designated space.
Select this model when protection against combustible dust is required rather than liquid ingress. The NEMA Type 9 rating distinguishes it from standard NEMA 12 enclosures used for general industrial environments. Verify that the internal volume of 16x12x8 inches provides sufficient space for the target components while maintaining necessary clearances.
This component belongs to the A9 Series of hazardous location enclosures. It is distinct from standard indoor enclosures due to its specialized sealing and construction designed to prevent dust ignition. The series includes various sizes tailored for different hazardous area classifications.
Direct substitutes must match the NEMA Type 9 classification and Class II Division compatibility. Generic NEMA 12 enclosures are not suitable replacements as they lack the specific dust-tight integrity required for these hazardous zones.
