APC by Schneider Electric AR3347 48U 750mm x 1200mm Networking Enclosure
Overview
The AR3347 is APC's NetShelter SX 48U open-frame-style networking enclosure built for data center rows, IDF closets, and network equipment rooms where you need a deep, structurally rigid rack that can handle dense switching and server loads without flex or vibration issues. At 750mm wide and 1200mm deep, it gives you the lateral room for cable management arms and the depth to seat even the longest 2-post or 4-post mounted gear cleanly. Explore the full APC by Schneider Electric catalog for compatible PDUs, cable managers, and blanking panels.
Key Features
- 48U Usable Space: 48 rack units in a single footprint (88.90 in tall / 225.8 cm) means you can consolidate switches, patch panels, cable managers, and 1U appliances in one cabinet rather than splitting across two — fewer footprints, shorter cable runs.
- 2,250 lb Static / 3,750 lb Dynamic Load Rating: The static rating handles fully populated dense switching environments; the dynamic rating means the cabinet can be rolled into position loaded without structural risk. The 14-gauge EIA mounting rails are the backbone here — heavier gauge than the 16-gauge door and post steel, placing material where racking loads actually concentrate.
- 37.75 in Maximum Mounting Depth: Accommodates the longest rack-mount gear on the market (up to 95.89 cm usable depth). Minimum mounting depth of 11 in (27.94 cm) means shallow 1U patch panels and 2U UPS units don't rattle loose either.
- 19-inch EIA-310E Rail Standard: Every standard rack-mount device fits without adapters. EIA-310E compliance means consistent hole spacing and threading — no surprises when mixing vendors in the same cabinet.
- TAA and BAA Compliance: Both Trade Agreements Act and Buy American Act compliant, which matters for federal, state, and public-sector bids. Verify at the project level, but the AR3347 passes both gatekeeping requirements out of the box.
- UL 2416 / UL 60950-1 Listed: UL 2416 is the rack enclosure safety standard; UL 60950-1 covers IT equipment. Dual-listed status satisfies most AHJ and facilities sign-off requirements for data rooms and wiring closets.
- 5-Year Manufacturer Warranty (Repair or Replace): APC's 5-year repair-or-replace coverage is longer than the 3-year terms common on competing enclosures — meaningful when the cabinet will outlive several generations of gear installed inside it.
Integration and Compatibility
The AR3347 is designed to accept the full range of APC NetShelter SX accessories — side panels, roof sections, power distribution units, and cable management channels — allowing you to build out a complete enclosed row without sourcing from multiple vendors. The 750mm width accommodates standard side panels and blanking kits. For high-density PoE switching deployments, pair with a managed PoE switch and a rack-mount UPS to complete the infrastructure stack. Review the power and UPS category for compatible 2U and 3U rackmount units that fit the 37.75 in depth envelope. If you are planning a structured cabling build-out, the 1200mm depth leaves clearance for rear vertical cable managers without crowding patch panel access.
Frequently Asked Questions
Q: Is the AR3347 TAA and BAA compliant?
A: Yes. The AR3347 carries both TAA (Trade Agreements Act) and BAA (Buy American Act) compliance, making it eligible for federal and public-sector procurement without additional waivers.
Q: What is the static load capacity of the AR3347?
A: The AR3347 supports a permanent permissible static load of 2,250 lb (1,020.6 kg) and a dynamic load of 3,750 lb (1,701 kg), accommodating fully loaded high-density switching and server configurations.
Q: What is the warranty on the AR3347?
A: APC covers the AR3347 with a 5-year repair-or-replace manufacturer warranty.
Q: What is the maximum equipment mounting depth inside the AR3347?
A: Maximum mounting depth is 37.75 inches (95.89 cm), with a minimum of 11.00 inches (27.94 cm), accommodating virtually all standard rack-mount hardware from shallow patch panels to deep blade chassis.
Q: What gauge steel are the mounting rails on the AR3347?
A: The EIA mounting rails are 14-gauge steel — heavier than the 16-gauge used for the doors and posts — concentrating structural material at the primary load-bearing points.
Q: Does the AR3347 ship with side panels installed?
A: Side panels are not included with the base AR3347 enclosure. APC sells side panels as separate accessories in the NetShelter SX family, allowing you to configure open or closed sides based on airflow requirements.
The AR3347 is the enclosure I spec when a project calls for a 48U footprint with serious load tolerance and no ambiguity on government procurement compliance. The 2,250 lb static / 3,750 lb dynamic rating isn't marketing — those numbers hold up when you're populating 48U with dense PoE switching, patch panels, and a rackmount UPS stack simultaneously.
Technical Highlights:
- 14-Gauge Mounting Rails: Heavier than the 16-gauge door and post steel — load is distributed at the rail-to-chassis interface, which is where flex shows up first in cheaper enclosures under dense populations.
- 37.75 in Max Mounting Depth: Gives you clearance for rear cable management arms behind even the deepest 2-post mounted switches without pulling gear forward off the rails.
- TAA + BAA Dual Compliance: Both marks on a single SKU means the AR3347 clears federal, state, and municipal procurement gatekeepers in one step — no variance requests, no substitution memos.
Deployment Considerations:
- At 408.85 lb empty and 458.96 lb packaged, delivery and placement logistics need to be planned — this is a two-person minimum lift and may require a pallet jack for final positioning on raised floor environments.
- Side panels are not included; budget for them separately if the deployment requires enclosed airflow management or physical security on open-aisle rows.
The AR3347 is the right call for federal network closets, campus IDF buildouts, and any project where TAA/BAA compliance is a bid requirement and you need a 48U envelope that won't flex under a fully populated switching stack.
