Overview

The Hoffman Enclosures A90XD4EW18FTCLPG is a gray steel disconnect enclosure designed for the SEQUESTER External Disconnect Package. It features four doors and meets NEMA Type 12 and IP55 ratings. The unit measures 90.12 inches in length, 158 inches in width, and 18.12 inches in depth (2289 mm x 4013 mm x 460 mm). Constructed from heavy-duty steel, it provides isolation of incoming power to mitigate arc flash risks during maintenance.

Feature Summary

• Four-door design for comprehensive access
• SEQUESTER package integration for external disconnect isolation
• NEMA Type 12 and IP55 environmental protection

Applications

• Industrial electrical distribution systems requiring arc flash mitigation
• Facilities needing isolated line-side power disconnection
• Heavy-duty commercial environments with dust and dripping liquid exposure

Procurement Notes

Verify that the specific installation site accommodates the large footprint dimensions of 90x158 inches. Confirm compatibility with existing SEQUESTER disconnect hardware. Ensure structural support is adequate for the steel enclosure weight. Check local electrical codes regarding external disconnect placement requirements before finalizing procurement.

Selection Notes

Select this model when high-capacity isolation is required for large-scale industrial equipment. The four-door configuration allows organized access to multiple disconnect points. Consider the significant physical size and ensure sufficient floor space is available. Verify that the NEMA 12 rating aligns with the specific environmental hazards present at the installation location.

Part Context

This component belongs to the nVent HOFFMAN SEQUESTER series, which specializes in safety-focused disconnect solutions. These enclosures are engineered to enhance worker safety by physically separating incoming power sources from internal components. The product line emphasizes robust construction and compliance with stringent industrial safety standards for hazardous energy control.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific SEQUESTER package configuration. Replacement requires matching the exact dimensional constraints and SEQUESTER interface specifications. Consult manufacturer documentation for updated series equivalents if discontinuation occurs.
