Overview

The nVent A90XM4020SSN4 is a Type 4X floor-mount disconnect enclosure constructed from 12-gauge Type 304 stainless steel with a smooth #4 brushed finish. This single-door enclosure features a secure 3-point latching mechanism and measures 90.12 x 40.25 x 18.12 inches (2290 x 1022 x 460 mm), providing ample space for housing disconnect switches and circuit breakers. The continuous seam welding and ground smooth seams ensure superior corrosion resistance and environmental protection against water, dust, and contaminants. Designed for demanding industrial environments, this enclosure meets UL508A, cUL, NEMA Type 4X, and IEC 60529 IP66 standards. Its robust construction includes body stiffeners for extra rigidity and heavy-duty lifting eyes for safe installation. The Type 4X rating makes it suitable for both indoor and outdoor applications in food and beverage processing, packaging, water/wastewater treatment, and petroleum/chemical processing industries. The brushed SS304 finish resists minor abrasions and corrosion, outperforming carbon steel or painted enclosures in wet or chemically aggressive environments. The removable centerpost and trough collar design exclude liquids and contaminants, preventing equipment failure and downtime. With a 3-point latch system, this enclosure maintains a tight seal to safeguard critical electrical controls and components.
