APC by Schneider Electric AR3340 NetShelter SX 42U Networking Rack Enclosure

Overview

The APC by Schneider Electric AR3340 is a 42U freestanding networking enclosure built for high-density IT and network infrastructure deployments — the kind of rack that goes into a serious data center, IDF closet, or enterprise network core where structural integrity and cable management are non-negotiable. At 750 mm wide and 1200 mm deep, it gives you the real estate to house full-depth servers, high-port-count switches, and dense patch panels without the compromises of a shallower enclosure. If you are spec'ing a rack for anything beyond lightweight AV or surveillance gear, the AR3340's load ratings and adjustable mounting depth put it in a different class than standard 4-post open frames.

Key Features

• 42U Rack Capacity: Forty-two rack units in a single enclosure means you can consolidate an entire network closet — core switches, firewall appliances, patch panels, cable management — without stacking multiple shorter racks side by side. More U means fewer enclosures to power, ground, and manage.
• 1704 kg Static Load / 1022.73 kg Dynamic Load: The static load rating of 1704 kg is high enough that you will never realistically hit it in a standard IT deployment. The dynamic (rolling) load of 1022.73 kg is the more operationally relevant figure — it tells you how much weight the rack can sustain while being moved across a data center floor without racking damage or tip risk.
• 750 mm Wide Footprint: The 750 mm width accommodates standard 19-inch (48.3 cm) EIA-310 equipment on the rack rails while providing generous side clearance for cable routing and airflow. Narrower 600 mm racks force bundled, compressed cable runs; the extra 150 mm here translates directly into cleaner structured cabling and better hot-aisle/cold-aisle separation.
• 1200 mm Depth with 27.9–95.9 cm Adjustable Mounting Depth: The 1200 mm enclosure depth accommodates full-depth server hardware and high-port-density networking gear. The adjustable rail range of 27.9 cm (minimum) to 95.9 cm (maximum) means shallow 1U switches and deep 4-post servers both mount cleanly on the same rail set — no secondary rail kit required for most equipment.
• 1991 mm Usable Height: At just under 2 meters tall, the AR3340 fits within standard data center floor-to-ceiling clearances, including raised-floor environments with overhead cable trays, while maximizing U density in the footprint.
• Sides Included: The enclosure ships with side panels, which matters for airflow containment and physical security. In open-row deployments, side panels are the first line of defense against cross-aisle air bypass that degrades cooling efficiency and drives up PUE.
• UL 60950-1, RoHS, REACH Certified: UL 60950-1 certification confirms the enclosure meets safety standards for IT equipment — relevant if your facilities team or insurer requires listed equipment in the rack space. RoHS and REACH compliance simplifies procurement for EU-regulated environments and sustainability-conscious enterprise buyers.
• Black Finish: Consistent black finish across the NetShelter SX line means mixed-row deployments maintain visual uniformity — a minor point operationally, but a real consideration in customer-facing data centers and co-location environments.

Integration and Compatibility

The AR3340 is designed around the industry-standard 19-inch (EIA-310) rack form factor, meaning virtually all enterprise networking, server, and storage equipment installs without adapter hardware. The adjustable mounting depth range of 27.9 to 95.9 cm covers the full spectrum from shallow patch panels and 1U switches to deep dual-socket servers and high-density storage arrays. The 750 mm width and 1200 mm depth match the standard NetShelter SX footprint, so the AR3340 installs natively in multi-rack rows alongside other NetShelter SX enclosures for side-by-side cable management and containment accessories. As part of the APC by Schneider Electric rack enclosure ecosystem, the AR3340 supports APC's full range of PDUs, cable management accessories, and containment systems. When planning your rack infrastructure, pairing this enclosure with a rack-mount PDU and structured cable management accessories will complete a code-compliant, serviceable installation.

Frequently Asked Questions

Q: What is the maximum static load capacity of the AR3340?

A: The AR3340 has a verified static load capacity of 1,704 kg. The dynamic (rolling) load rating is 1,022.73 kg, which applies when moving the loaded rack across a floor.

Q: What mounting depth range does the AR3340 support?

A: The AR3340 supports an adjustable mounting depth of 27.9 cm (minimum) to 95.9 cm (maximum), accommodating shallow patch panels through full-depth dual-socket servers on the same rail set.

Q: Does the AR3340 include side panels?

A: Yes. The AR3340 ships with side panels installed, which support airflow containment and physical security in open-row deployments.

Q: What certifications does the AR3340 carry?

A: The AR3340 is certified to UL 60950-1 (IT equipment safety), RoHS (restriction of hazardous substances), and REACH (chemical substance registration). These are relevant for facilities compliance, EU procurement, and sustainability reporting.

Q: What are the overall dimensions of the AR3340?

A: The AR3340 measures 750 mm wide × 1,200 mm deep × 1,991 mm tall (WxDxH). Packaged dimensions are 850 mm × 1,320 mm × 2,118 mm, with a package weight of 183.2 kg.

Q: Is the AR3340 compatible with standard 19-inch rack equipment?

A: Yes. The AR3340 accommodates standard 19-inch (48.3 cm / EIA-310) rack-mount equipment across its 42U height, which covers essentially all enterprise networking, server, storage, and power distribution hardware without adapter hardware.
