APC by Schneider Electric AR3103 NetShelter SX 12U Rack Enclosure
Overview
The AR3103 is APC by Schneider Electric's NetShelter SX 12U rack enclosure, built to a 600mm wide by 1070mm deep footprint — a compact-depth profile that fits tight IDF closets, edge deployments, and smaller server rooms where a full 1200mm deep cabinet would be impractical. The hinged door and all-steel construction make this a durable, serviceable enclosure for network switches, patch panels, and edge compute hardware in commercial and light-industrial environments.

Key Features
- 12U Capacity: twelve rack units of usable space — enough for a compact network stack (core switch, patch panel, a 1U server or NVR) without committing to a larger footprint. Right-sized for branch offices, IDF closets, and surveillance head-end rooms.
- 600mm Width: standard 19-inch rack rail spacing inside a 600mm-wide chassis — compatible with virtually all 19-inch rackmount equipment including network video recorders, PoE switches, and UPS units without adapter rails.
- 1070mm Depth: shallower than the 1200mm standard NetShelter SX deep cabinets, this depth handles most 1U and 2U network appliances while leaving clearance for cable management in confined rooms. Verify your deepest component's cable-exit length before ordering.
- Hinged Door: the hinged front access design allows full-swing service access without unracking the door — a time saver during installs and maintenance cycles in tight spaces where a removable door creates a storage problem.
- All-Steel Construction: stainless steel chassis delivers structural rigidity and long service life. This is a commercial-grade enclosure built to hold loaded rackmount equipment securely, not a light-duty open frame.
- Black Finish: standard black finish blends into server room and IDF environments and matches APC's broader rack enclosure ecosystem for mixed-cabinet deployments.
Integration and Compatibility
The AR3103 is designed for standard 19-inch rackmount equipment. At 12U and 1070mm depth, it is well-matched for PoE network switches, 1U/2U NVRs, patch panels, and small UPS units. Confirm that any equipment exceeding 900mm in depth (with cables attached) can be accommodated before deployment. APC offers compatible PDUs, blanking panels, and cable management accessories within the NetShelter SX line.
