APC by Schneider Electric Netshelter SX 48U 750MM Wide X 1200MM Deep Networking Enclosure - AR3347W

APC by Schneider Electric AR3347W NetShelter SX 48U Networking Enclosure

Overview

The APC by Schneider Electric AR3347W is a 48U freestanding networking enclosure built for high-density IT and network infrastructure environments. At 750mm wide and 1200mm deep, it accommodates deep switching, patch panels, and UPS equipment that shallower enclosures simply cannot house — and its 1,020 kg rated load capacity means you can fill every U without engineering a workaround. If you're speccing a network closet, data room, or telecom head-end where gear density and cable management both matter, this is the enclosure to start with.

The AR3347W ships in white, making it a natural fit for environments where aesthetics are a secondary operational requirement — broadcast facilities, retail back-of-house, or anywhere the enclosure needs to blend with a light-colored interior rather than the traditional black server room aesthetic.

Key Features

• 48U Usable Height: 48U gives you enough vertical real estate to consolidate switching, patch, power distribution, and even edge compute into a single enclosure — reducing floor footprint and cable runs between racks. At most facilities, that's the difference between two cabinets and one.
• 1,020 kg Maximum Load Rating: Dense networking gear — core switches, high-density fiber panels, in-row UPS units — adds up fast. The 1,020 kg structural rating means you're not artificially constraining what you can install, and you won't need to re-engineer weight distribution after the fact.
• 750mm Wide x 1200mm Deep Footprint: The 750mm width accommodates wide-body equipment and side-exit cable management trays simultaneously. The 1,200mm depth handles the longest 2-post and 4-post gear on the market — including large modular switches and extended-depth UPS chassis — without forcing equipment to hang out the back.
• Perforated Front and Back Doors: Both doors use perforated construction, which promotes passive airflow through the enclosure. For gear that generates significant heat — core switches, high-density patch environments — perforated doors reduce the delta-T between inlet and exhaust air without requiring active supplemental cooling panels in most deployments. Pair with hot/cold aisle containment for a structured enclosure layout.
• Adjustable Mounting Rails with Square Hole Pattern: Square mounting holes accept standard cage nuts and work with virtually every rackmount vendor's rail kits — no proprietary tooling required. Adjustable depth on the rails means you can set the rail position for short 1U appliances or deep chassis without swapping hardware.
• Adjustable Depth, Feet, and Stand: All four feet are independently adjustable, which is the right answer for concrete floors that aren't perfectly level — especially in older buildings or industrial facilities where poured floors have settled unevenly. The adjustable stand provides additional stability for fully loaded configurations.
• Key-Locked Front Door: Physical access control is the first line of defense for networking gear. The front door key lock ensures that incidental physical access — cleaning staff, unauthorized personnel — doesn't translate into access to live ports, patch panels, or management interfaces. Plan your network equipment access policy around it.
• Integrated Castor Wheels: Castor wheels are not just a convenience — they're a practical necessity during initial deployment in any facility where the final installation position requires maneuvering through doorways or around existing infrastructure. Once positioned, lock the castors and level with the adjustable feet.
• IP20 Environmental Rating: IP20 confirms protection against solid objects larger than 12mm (fingers, tools) but does not provide dust or water ingress protection. This enclosure is rated for controlled indoor environments — standard data rooms, network closets, and telecommunications rooms — not exposed or industrial spaces where dust ingress is a concern.
• Schneider Electric Cooling Ecosystem Compatibility: The AR3347W is designed to integrate with Schneider Electric's broader thermal management portfolio. If your rack density exceeds what passive perforated-door airflow handles, you can add in-row cooling panels, blanking panels, or airflow management accessories without replacing the enclosure.

Integration and Compatibility

The AR3347W uses standard square-hole mounting with 6.4mm rail thickness — compatible with the full range of rackmount equipment from networking, compute, storage, and power distribution vendors. The adjustable mounting rails accommodate equipment from standard 1U patch panels up to deep chassis that require rail position adjustments. For network switch deployments, verify the depth of your specific switch model against the 1,200mm internal depth to confirm clearance for cable egress at the rear.

The enclosure integrates directly with APC by Schneider Electric's NetShelter accessory ecosystem, including side panels, roof sections, blanking panels, cable management arms, and power distribution units designed to mount within the standard rail pattern. If you are building a multi-enclosure row, note that the 750mm wide footprint allows for end-to-end alignment with other NetShelter SX units for row-level cable management and containment systems.

Frequently Asked Questions

Q: What is the maximum weight capacity of the AR3347W?

A: The AR3347W is rated to support a maximum load of 1,020.58 kg (approximately 2,250 lbs). This is the structural limit for the enclosure — plan your populated rack weight carefully when installing high-density switching, UPS, or storage equipment.

Q: What mounting hole pattern does the AR3347W use?

A: The AR3347W uses square mounting holes, which accept standard cage nuts and are compatible with the vast majority of rackmount equipment from all major vendors. No proprietary mounting hardware is required.

Q: Is the AR3347W suitable for outdoor or industrial environments?

A: No. The AR3347W carries an IP20 rating, which means it is designed for controlled indoor environments only. IP20 provides protection against solid objects over 12mm but offers no protection against dust or water ingress. For exposed or harsh environments, a higher IP-rated enclosure is required.

Q: Can the AR3347W be integrated into a multi-enclosure hot/cold aisle containment row?

A: Yes. The 750mm width is a standard NetShelter SX dimension that aligns with APC's containment accessories and other enclosures in the NetShelter SX family. End-to-end row alignment and Schneider Electric's aisle containment systems are designed around this footprint.

Q: Does the AR3347W ship with side panels included?

A: The product name references sides (
