APC NetShelter ES AR3300X721 40U 600 mm x 1,200 mm | Rack Enclosure

Keep server infrastructure organized, protected, and easier to service with the APC NetShelter ES 40U enclosure. Sized at 600 mm wide and 1,200 mm deep, it gives IT teams the space needed for mixed server and networking deployments without wasting valuable floor area. The 40U height supports substantial equipment density, making it a practical fit for enterprise closets, edge rooms, and data center rows where rack consistency matters. This enclosure is designed for the realities of production environments: stable floor-standing construction, room for structured cable routing, and a footprint that supports orderly airflow around active equipment. For teams standardizing on APC rack infrastructure, it offers a familiar enclosure format that helps simplify deployment planning and long-term maintenance. The NetShelter ES line is a strong choice when you need more than a basic frame. It provides the enclosure depth required for modern hardware, while preserving the serviceability and physical protection that help reduce disruption during moves, adds, and changes. Backed by a 5-year limited warranty and RoHS compliance, it is built for organizations that expect rack infrastructure to hold up over time.
