Procurement Notes

Verify the specific manufacturer part number against official nVent Hoffman documentation to ensure compatibility with existing infrastructure. Confirm that the Grade 304 stainless steel material meets project specifications for corrosion resistance. Ensure the physical dimensions of 90x40x20 inches fit the designated installation footprint. Validate the NEMA Type 4X rating aligns with the required environmental protection standards for the intended deployment location.

Selection Notes

Select this model when a robust, floor-mounted solution is required for housing sensitive electronic equipment. The Grade 304 stainless steel construction offers superior resistance compared to standard carbon steel options. The three-point latch ensures secure closure against environmental ingress. Consider the substantial physical footprint and weight associated with the 90-inch height during site planning and structural support assessment.

Part Context

This component belongs to the Hoffman series of industrial electrical enclosures designed for demanding operational conditions. The product line emphasizes durable materials and high ingress protection ratings. As a disconnect enclosure, it serves as a critical interface for isolating power to downstream equipment while maintaining safety standards in harsh industrial environments.
