APC NetShelter SX AR3357X674 52U 750 mm x 1,200 mm | Rack Enclosure

Give dense infrastructure the space it needs to stay serviceable. The APC NetShelter SX AR3357X674 provides 52U of rack capacity in a 750 mm wide by 1,200 mm deep enclosure, creating room for larger equipment footprints, cleaner cable paths, and better access during installation and maintenance. Compared with narrower cabinets, the 750 mm width offers more lateral space for power cabling and airflow management, which becomes important as rack density rises. The 1,200 mm depth supports modern servers, storage systems, and network gear that need rear clearance without forcing awkward cable bends or cramped service access. Side panels help preserve enclosure integrity and keep the rack environment controlled. This is the kind of enclosure infrastructure teams choose when the rack must support growth, not just current load. The 52U height gives more usable vertical space for consolidation, while the black finish and APC platform fit cleanly into standardized enterprise rows. For data centers, colocation suites, and on-premises facilities, it delivers the physical structure required for high-value equipment deployments.
