APC by Schneider Electric AR3307 48U 600mm Wide x 1200mm Deep Server Rack Enclosure
Overview
The AR3307 is a 48U NetShelter SX enclosure designed for high-density IT and security infrastructure deployments where physical capacity, cable management headroom, and long-term serviceability matter. At 600mm wide and 1200mm deep (usable depth 47.2"), this cabinet handles the full stack of modern equipment — deep 1U servers, UPS units, patch panels, and network switches — without the compromises you get from shallower alternatives. If you're building out a purpose-built security operations room, a secondary data center closet, or a structured wiring room for a large campus, the AR3307 is sized to grow with the deployment rather than cap it.
The enclosure ships in black with EIA-310-D compliance, meaning your standard 19-inch rack-mount equipment installs directly with no adapter gymnastics. Mounting depth adjusts from 7.52 inches (191mm) minimum to 41.73 inches (1060mm) maximum — a range that accommodates everything from thin patch panels to full-depth 1U blade chassis without repositioning the rail set.
Key Features
- 48U of Usable Rack Space: 48 rack units in a single footprint means you can consolidate what would otherwise require two mid-sized cabinets. For a network video recorder stack paired with PoE switches and patch infrastructure, that vertical real estate translates directly to fewer physical enclosures to cable, power, and cool.
- 3,000 lb Static / 2,250 lb Dynamic Load Capacity: The 3,000 lb static rating means you can fully load this cabinet with dense storage arrays, UPS modules, or stacked NVR appliances without structural concern. The 2,250 lb dynamic rating is the more operationally relevant figure — it covers the load the enclosure handles while being moved on casters across a raised floor or data hall, which matters during initial commissioning and equipment swaps.
- 600mm Width: The 600mm (23.6") exterior width is the standard data center footprint — compatible with hot/cold aisle containment systems, overhead cable trays, and tile cutouts designed to the 600mm grid. Stepping up to 800mm wide cabinets is unnecessary unless you're running side-by-side dual-deep configurations.
- 1200mm Depth with 47.2" Usable Interior: The 1200mm exterior depth yields 47.2 inches (1199mm) usable — enough clearance to install the longest 1U servers and still maintain rear cable management. Shallow 900mm cabinets force cable bundling that blocks airflow; the AR3307's extra depth eliminates that tradeoff.
- Adjustable Mounting Depth (7.52" to 41.73"): The wide rail adjustment range means you can mount shallow 1U switches at the front and deep UPS units in the same cabinet without custom hardware. This is the kind of flexibility that prevents mid-project procurement delays when equipment specs change after the cabinet order is placed.
- Perforated Split-Front Door: The perforated split door supports natural convection and forced airflow while providing physical security via a locking handle. The split design lets you open one half for rear access in tight aisle configurations without swinging a full-width door into adjacent equipment.
- Lift-Off Side Panels: Side panels remove completely rather than hinge — useful in constrained equipment rooms where a hinged panel would collide with a wall or adjacent rack. Pull them off for initial cable installation, replace them when the build is complete.
- EIA-310-D Compliance: Standard EIA-310-D rail spacing means your existing rack-mount ears, cage nut hardware, and slide rail kits work without modification. No proprietary tooling required during build-out.
Integration & Compatibility
The AR3307 integrates with the full APC by Schneider Electric ecosystem — NetShelter SX blanking panels, cable management arms, side-channel cable managers, vertical PDU brackets, and roof/floor gland plates all mount without modification. Third-party PDUs, patch panels, and KVM drawers sized to the EIA-310-D standard install identically. If you're specifying rack enclosures for a standardized deployment across multiple sites, the SX line offers consistent dimensions and accessory compatibility across the family, simplifying spare parts and tooling.
For airflow management, the perforated door and 1200mm depth support both front-to-rear and bottom-to-top airflow configurations. Pair with blanking panels in unused rack units to prevent hot-air recirculation — a detail that matters more in high-density builds than in lightly loaded cabinets.
Frequently Asked Questions
Q: What is the maximum equipment depth the AR3307 can accommodate?
A: The AR3307 provides 47.2 inches (1199mm) of usable internal depth, with mounting rail positions adjustable from 7.52 inches (191mm) to 41.73 inches (1060mm) from the front of the cabinet. This covers virtually all standard 1U rack-mount servers, UPS units, and deep storage appliances without modification.
Q: How much weight can the AR3307 hold?
A: The AR3307 has a static load capacity of 3,000 lbs (1,363 kg) — meaning fully loaded and stationary. The dynamic load rating is 2,250 lbs (1,022 kg), which applies when the enclosure is being moved. For typical IT and security infrastructure builds, neither limit is a practical constraint.
Q: Does the AR3307 include side panels?
A: Yes. The AR3307 ships with lift-off side panels included. They remove completely (no hinge) for installation access and can be replaced once cabling is complete.
Q: Is the AR3307 compatible with standard 19-inch rack-mount equipment?
A: Yes. The AR3307 complies with EIA-310-D, which defines the standard 19-inch rack-mount hole pattern. Standard cage nuts, rack screws, and slide rail kits work without adapters.
Q: What door type does the AR3307 use?
A: The AR3307 uses a perforated split front door with a locking handle. The perforation supports airflow, and the split design allows partial opening in tight aisle configurations.
Q: Is the AR3307 part of APC's NetShelter SX line, and does that affect accessory compatibility?
A: Yes, the AR3307 is a NetShelter SX enclosure. This means it is compatible with the full NetShelter SX accessory family — including blanking panels, side cable managers, PDU brackets, and roof/floor gland kits — without custom adapters.
I spec the AR3307 when a project needs consolidation capacity without compromising on serviceability. The 3,000 lb static load rating and 47.2-inch usable depth mean this cabinet can absorb a fully loaded NVR stack, a pair of PoE switches, a UPS module, and a full patch bay in one footprint — and still have rail adjustment range left over. If your equipment list is still evolving at bid time, that 7.52-to-41.73-inch mounting depth window is meaningful insurance.
Technical Highlights:
- 3,000 lb Static Capacity: Dense security infrastructure — stacked NVRs, battery UPS modules, high-port-count switches — can easily approach 1,500+ lbs in a 48U build. The AR3307's 3,000 lb ceiling means you're not engineering around weight constraints mid-project.
- 47.2" Usable Depth: Full-depth servers and extended UPS chassis need every inch of that 47.2-inch interior. Cabinets with 900mm or 1000mm exterior depth force cable compromise at the rear; the 1200mm footprint eliminates that problem.
- Lift-Off Side Panels: In a single-row equipment room with walls on two sides, hinged panels are a liability. Lift-off panels on the AR3307 come off completely — useful during initial cable pulls and equipment population when side clearance is limited.
Deployment Considerations:
- At 329 lbs net weight before equipment, verify your raised floor tile or concrete slab loading — particularly in older buildings where point loads near floor penetrations can be a concern. Factor the 2,250 lb dynamic rating when planning move-in routes through doorways and corridors.
- The 600mm width is the data center standard, but confirm your aisle containment system is sized for 600mm cabinets specifically — some containment kits are dimensioned for 800mm and require filler panels when mixed with 600mm enclosures.
The AR3307 is the right call for a purpose-built security operations room or a campus IDF closet where 48U of consolidated, deep-rack capacity needs to outlast two or three equipment refresh cycles without the cabinet becoming the constraint.
