The A90XM4EW18FTC is a heavy-duty free-standing disconnect enclosure manufactured by nVent Hoffman. Constructed from steel with a gray finish, it features dimensions of 90.12 inches in height, 157.5 inches in width, and 18.12 inches in depth. The unit provides NEMA Type 12 and IP55 protection ratings, ensuring resistance to dust, dirt, and dripping non-corrosive liquids. It is designed for industrial electrical applications requiring robust physical protection.
Verify exact dimensional requirements against site constraints due to the large footprint. Confirm that the specific door configuration matches the intended disconnect switch layout. Ensure structural support is adequate for the free-standing steel assembly. Check local electrical codes for NEMA 12 compliance in the installation environment.
Select this model when high ingress protection is required for large disconnect assemblies. Consider the significant spatial requirements for the 157.5-inch width. Evaluate if the standard steel material meets corrosion resistance needs or if specialized coatings are necessary for harsh environments.
This component belongs to the nVent Hoffman series of industrial enclosures. It is part of a modular system allowing for various door configurations. The product line focuses on providing secure, standardized housing for critical electrical components in demanding industrial settings.
Cross-reference with other nVent Hoffman models offering similar NEMA 12 ratings. Verify compatibility with existing mounting structures. Ensure substitute parts maintain the same depth and height specifications for panel fitment.
