Procurement Notes

Verify that the specific order matches the A664DL part number to ensure correct dimensions of 6x6x4 inches and Type 12 rating. Confirm the material is drawn steel rather than welded construction. Check for UL 508A and CUL certification marks on the product documentation. Ensure the gray ANSI 61 finish is required for the installation environment.

Selection Notes

Select this model when a compact, indoor-rated enclosure is needed for junction box duties. The Type 12 rating makes it suitable for areas exposed to dust and non-corrosive liquid splashes like oil. The removable hinge design facilitates easier wiring access compared to fixed-hinge models. Ensure the application does not require outdoor exposure or higher ingress protection ratings.

Part Context

This component belongs to the nVent Hoffman A664 series of steel enclosures. These units are designed for general-purpose industrial use where moderate environmental protection is sufficient. The series offers various sizes while maintaining consistent construction quality with drawn steel bodies and standardized mounting configurations.

Replacement Considerations

Direct replacements must match the 6x6x4 inch footprint and Type 12 rating. Verify that substitute models also feature removable hinges if accessibility is critical. Ensure the replacement maintains UL 508A listing for compatibility with existing panel schedules.
