A90XM7818FTC

Overview

The A90XM7818FTC is a heavy-duty, free-standing disconnect enclosure manufactured by Hoffman Enclosures, Inc. Constructed from 11-gauge steel with a polyester powder-painted finish, it features a white interior and gray exterior. The unit measures 90.12 inches in length, 78.50 inches in width, and 18.12 inches in height. It provides NEMA Type 12 and IP55 protection ratings, ensuring resistance to dust, dripping water, and oil. The design includes continuously welded and ground-smooth seams, body stiffeners for rigidity, and a body flange trough designed to exclude liquids.

Feature Summary

• Heavy-duty construction using 11-gauge steel with continuously welded and ground-smooth seams
• Body stiffeners integrated into larger enclosures to provide extra structural rigidity
• Body flange trough engineered to effectively exclude liquids from entering the enclosure
• NEMA Type 12 and IP55 rated protection against environmental contaminants

Applications

• Free-standing circuit breaker installations
• Disconnect switch housing
• Industrial electrical distribution panels
• Environments requiring protection from dust and oil

Procurement Notes

Verify the specific dimensional requirements against the official datasheet, as variations exist between wall-mount and free-standing models within the same series. Confirm that the 11-gauge steel thickness meets the mechanical load requirements of the intended installation. Ensure the NEMA Type 12 rating aligns with the environmental conditions of the deployment site. Cross-reference the part number with current manufacturer documentation to confirm availability and standard lead times.

Selection Notes

Select this model when a free-standing configuration is required rather than wall-mounting. The 11-gauge steel construction offers enhanced durability compared to lighter gauges. The white interior aids in visual inspection of components, while the gray exterior provides corrosion resistance. Consider the overall footprint of 90.12 x 78.50 inches to ensure adequate floor space is available for installation and maintenance access.

Part Context

This component belongs to the Hoffman A90XM series of disconnect enclosures. It is designed for industrial applications where robust protection and high capacity are necessary. The series includes various configurations, including one- to four-door wall-mount and one- to five-door free-standing models. This specific part represents a large-format, heavy-duty option suitable for significant electrical infrastructure.

Replacement Considerations

Direct substitutes may include other NEMA Type 12 free-standing disconnect enclosures from Hoffman or compatible manufacturers like Hammond Manufacturing, provided dimensions and gauge thickness match. Verify compatibility with existing mounting hardware and internal component layouts before substitution.
