The Hoffman A90XM3EW24FTCLPG is a heavy-duty, free-standing disconnect enclosure constructed from steel with a gray finish. It features a three-door design without pre-installed panels and meets NEMA Type 12 and IP55 ratings for protection against dust and dripping water. The unit measures 90.12 inches in height, 118.75 inches in width, and 24.12 inches in depth. It utilizes a three-point latch mechanism secured by a padlock handle to ensure security.
Verify that the specific project requirements align with the NEMA 12 rating, as this enclosure is intended for indoor use only and does not provide weatherproofing for outdoor exposure. Confirm that the three-door layout matches the spatial constraints of the installation site. Ensure that the absence of internal panels is acceptable, as these units are typically supplied empty for custom panel fabrication. Check local electrical codes regarding grounding and bonding requirements for steel enclosures.
Select this model when high ingress protection against dust and non-corrosive liquids is required in an indoor setting. The three-door design facilitates access to multiple circuit sections within a single footprint. Consider the significant physical dimensions (over 90 inches tall) during planning to ensure adequate clearance for door operation and maintenance access. Verify that the steel material thickness meets the mechanical strength requirements for the intended mounting environment.
This component belongs to the nVent Hoffman heavy-duty disconnect enclosure series, which focuses on robust steel constructions for demanding industrial applications. The product line emphasizes security and environmental protection through standardized ratings like NEMA 12. Similar models in the series may vary in door count, dimensions, or specific latch mechanisms, but generally share the same heavy-duty steel build quality and industrial-grade finishes.
Direct replacements must match the NEMA 12/IP55 rating and similar dimensional constraints. Verify compatibility with existing mounting infrastructure due to the large footprint. Alternative models may offer different door configurations or latch types, requiring assessment of security needs and accessibility requirements.
