D903646SDAS

Overview

The Hoffman Enclosures D903646SDAS is a Type 4X, dual-access, free-standing network seismic cabinet constructed from Grade 304 stainless steel. It features unibody design for structural integrity and includes 19-inch rack angles supporting up to 42 rack units. The enclosure measures 90.00 x 36.00 x 46.00 inches (approximately 91.0 x 37.0 x 47.0 inches). It provides protection ratings of NEMA 3R, 4, 4X, and 12, suitable for harsh industrial environments requiring corrosion resistance and seismic stability.

Feature Summary

• Dual-access configuration allowing entry from both sides
• Seismic-rated free-standing construction for earthquake-prone areas
• Grade 304 stainless steel material for corrosion resistance
• Integrated 19-inch rack angles for equipment mounting

Applications

• Network infrastructure in seismic zones
• Industrial control panels requiring Type 4X protection
• Outdoor or washdown environments needing stainless steel durability
• Data communication hubs requiring dual-side access

Procurement Notes

Verify the specific dimensional requirements against site constraints, as dimensions vary slightly between sources (90x36x46 vs 91x37x47). Confirm that the standard 19-inch rack angle spacing meets your equipment depth needs. Ensure the procurement order specifies the unpainted stainless steel finish. Check for any required accessories such as drip shields or installation kits if not included in the base unit configuration.

Selection Notes

Select this model when seismic certification and Type 4X environmental protection are mandatory. The dual-access feature is critical for maintenance in tight spaces or where rear access is needed. Grade 304 stainless steel is preferred over painted carbon steel for corrosive or hygienic applications. Consider the 42U capacity to ensure sufficient space for all required networking or control components without needing additional cabinets.

Part Context

This component belongs to the nVent Hoffman network and data cabinet series designed for robust industrial deployment. It is part of the Type 4X stainless steel lineup, which emphasizes durability and environmental sealing. The dual-access design distinguishes it from single-door models, offering flexibility in installation layouts. It serves as a primary housing solution for sensitive electronic equipment in demanding conditions.

Replacement Considerations

Direct substitutes may include other Hoffman Type 4X seismic cabinets with similar dimensions, such as the D903646SS series if seismic rating is not required. Verify compatibility with existing rack mounts and door configurations. Ensure replacement units maintain the same IP/NEMA ratings and material grade to preserve environmental protection standards.
