Overview

The nVent HOFFMAN A42H4212WFSSLP3PT Type 4X wallmount enclosure provides Type 4X protection for electrical and electronic components in harsh industrial environments. Constructed from 304 stainless steel with a durable brushed finish, this 42x42x12 inch enclosure resists corrosion from salt spray, chemicals, and extreme temperatures. It features a two-door design with a removable centerpost for simplified panel installation and maintenance. The enclosure includes HOFFMAN’s PowerGlide Handles and a 3-point latching system for secure closure and tamper resistance. A seamless foam-in-place gasket delivers IP66/IP67 ingress protection against dust, water, and contaminants, meeting NEMA Type 4X standards for windblown dust, rain, splashing water, and hose-directed water. Internal stiffeners maintain structural integrity without compromising internal space. Typical applications include industrial automation, telecommunications, renewable energy systems, food processing, chemical plants, wastewater treatment, and marine environments where equipment must operate reliably despite exposure to moisture and corrosive agents. The brushed stainless steel finish enhances corrosion resistance while providing a professional appearance suitable for cleanroom installations. Optional stainless steel or aluminum panels are available for customization.
