Feature → Stainless steel construction with an ANSI 61 gray painted finish delivers robust corrosion resistance and easy cleaning, reducing lifecycle costs. This translates to longer service intervals and lower replacement risk in washdown, coastal, or chemical environments, enabling predictable maintenance cycles for control panels and power distribution enclosures in food & beverage, water treatment, and process facilities. Feature → NEMA 4X protection provides dependable moisture and dust ingress resistance, reducing the risk of electrical faults in outdoor and harsh indoor spaces. Business impact includes lower failure rates and extended uptime, with applications spanning outdoor substations, chemical plants, and marine-adjacent installations where environmental exposure is a constant factor. Feature → Compact dimensions (10.18 in depth, 21.01 in height, 12 in width) and a 54 lb weight support easy site fit, quick handling, and straightforward retrofits in space-constrained panels. This enables faster installation in retrofit projects and more flexible mounting options in rack-and-stack or wall-mount configurations. Feature → UL/CUL listing and NEMA 4X certification simplify regulatory approvals and facility acceptance. Business value includes smoother inspection cycles, reduced compliance risk, and faster project commissioning across manufacturing, processing, and utilities environments. Feature → Guardian DP21 climate control compatibility and Eaton’s climate control product ecosystem streamline integration, spare parts, and service. This minimizes total cost of ownership by reducing cross-vendor inventory needs and speeding up maintenance windows for mission-critical enclosures in industrial infrastructure projects.

FAQs
The KNA4C3DP21LV uses standard enclosure mounting interfaces and is designed to integrate with common frame systems and Guardian DP21 climate control components. Verify mounting footprint (10.18 in depth, 21.01 in height, 12 in width) and plan for cable ingress, door orientation, andAccessibility to climate control interfaces to ensure a clean retrofit or new installation.
The enclosure offers NEMA 4X protection and UL/CUL listing, backed by stainless steel construction and ANSI 61 gray finish. These features translate to superior corrosion resistance, moisture exclusion, and long-term reliability in washdown and outdoor environments, reducing unplanned downtime and providing stable operating temperatures for mounted control gear.
Yes. The stainless steel body with ANSI 61 gray paint and NEMA 4X protection make it suitable for washdown-heavy industries like food & beverage and water/wastewater. Its robust climate-control integration helps maintain consistent internal conditions for PLCs, VFDs, and sensors, even in humid or aggressive process environments.
The KNA4C3DP21LV is NEMA 4X rated and UL/CUL listed, aligning with common industrial compliance requirements. This provides assurance during audits and inspections, simplifies site acceptance testing, and supports safe installation in regulated facilities without additional protective enclosures.
