The Hoffman A645DSC is a contoured steel junction box with dimensions of 5.750 inches in length, 4.000 inches in width, and 4.750 inches in height (146.05mm x 101.60mm x 120.65mm). It features a screw-on removable dome cover and is finished in ANSI 61 gray polyester powder paint. The enclosure has a capacity of 76.9 cubic inches and is constructed from steel. It carries UL 508A and CUL certifications.
Verify the specific NEMA rating designation across different distributor listings, as some sources cite Type 4/IP66 while others reference Type 13 or Type 12. Confirm that the unit does not include a back panel if internal mounting hardware is needed. Ensure the gray color matches project specifications, as finishes can vary by manufacturing batch.
Select this model for applications requiring a compact, economical steel enclosure without the need for an integrated back panel. The contoured shape and dome cover provide aesthetic appeal alongside functional protection. Verify dimensional constraints against available space, noting the specific depth and height measurements provided in official documentation.
This component belongs to the nVent Hoffman A645 series of contoured junction boxes. These enclosures are designed for wall or panel mounting and are widely used in industrial environments. The A645DSC specifically denotes the steel construction with a dome cover variant, distinguishing it from flat cover or aluminum versions within the same product family.
Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult official nVent Hoffman catalogs for direct equivalents or cross-reference based on exact dimensional and material requirements.
