Procurement Notes

Verify the specific part number suffixes for exact dimensions, material thickness, and accessory inclusion such as hinges or latches. Confirm that the selected model meets the required NEMA rating for your specific installation environment. Check for any regional compliance certifications if applicable. Ensure that the enclosure size accommodates all planned components with adequate clearance for heat dissipation and wiring.

Selection Notes

Select this model based on the required internal volume and external dimensions for your specific application. Consider the mounting orientation and available space for installation. Evaluate the need for additional accessories like gaskets, transformers, or fans if higher environmental protection or thermal management is required. Ensure the enclosure material and finish are compatible with the operating environment to prevent corrosion.

Part Context

This component belongs to Hoffman's line of standard steel enclosures, widely used in industrial automation and control systems. It represents a common solution for protecting electrical components from dust and accidental contact. The series offers various sizes to accommodate different levels of complexity in control circuits, providing a standardized approach to equipment housing.

Replacement Considerations

When replacing existing units, verify dimensional compatibility and mounting hole patterns. Ensure the new enclosure meets or exceeds the original NEMA rating. Check for differences in door swing direction or latch mechanisms that might affect accessibility. Confirm that any necessary accessories are included or ordered separately.
