APC by Schneider Electric Netshelter SX 48U 800MM Wide X 1200MM Deep Enclosure with Sides - AR3387

APC by Schneider Electric AR3387 NetShelter SX 48U 800x1200mm Rack Enclosure

Overview

The AR3387 is APC's 48U NetShelter SX freestanding rack enclosure, sized at 800mm wide by 1,200mm deep — the configuration that fits dense server, storage, and network infrastructure without requiring a custom footprint. It ships with side panels installed, a keyed front door, and a keyed side-panel lock, making it a complete, deployable cabinet out of the box rather than a stripped shell you finish configuring on the floor. If you're speccing a new equipment room, IDF closet, or colocation cage and need a rack that handles heavy, deep equipment while keeping cabling organized and hardware physically secured, the AR3387 is worth a close look.

Key Features

• 48U Capacity: 48 rack units of usable space give you room to grow without buying a second cabinet prematurely. A fully loaded enterprise row often mixes 1U switches, 2U servers, and 4U storage arrays — 48U handles a realistic mix of all three in a single enclosure.
• 1,700 kg Static Load Rating: High-density blade chassis and storage arrays can easily exceed 1,000 lbs in a fully populated rack. The AR3387's 1,700 kg static capacity means the cabinet structure itself is not your limiting factor — your floor loading spec is. Verify your raised-floor or concrete slab rating before the rack arrives.
• 272 kg Rolling Load Capacity: The integrated castor wheels are rated to 272 kg in motion, which is enough for a partially loaded rack to be repositioned on a level data center floor without disassembly. That matters during initial installation and any future row reconfiguration, but do not roll a fully populated high-density rack — transfer weight to the leveling feet before rolling.
• 800mm Width: The 800mm wide form factor is the standard for high-density cabling environments. It provides the side-cable-management clearance that 600mm racks sacrifice, and it matches most rack accessories and cable management trays designed for enterprise deployments.
• 1,200mm Depth: Extended-depth gear — full-depth servers, top-of-rack switches with long cable tails, UPS systems — fits inside 1,200mm of internal depth with room for rear cable management. Shallow 800mm racks require rear-mounted shelf extensions for this class of equipment; the AR3387 does not.
• Adjustable Mounting Rails: Rails slide fore and aft within the 1,200mm depth envelope, accommodating equipment with varying mounting depths. You won't need after-market rail adapters for most commercial server and network gear.
• Square Mounting Holes: The industry-standard square-hole pattern is compatible with cage-nut hardware from virtually every major equipment vendor. No threading, no proprietary fasteners — faster installation, easier swaps.
• Keyed Front Door + Keyed Side Panels: Both the front door and the removable side panels are individually locked with key cylinders. Physical security at the enclosure level is a baseline requirement in any shared equipment room or IDF. Keys are independent, so front-of-rack access and full panel removal are separately controlled.
• Removable Side Panels: Side panels detach for back-to-back or side-by-side row configurations and for cable runs that need lateral access. The AR3387 ships with side panels included — you're not ordering them separately after the fact.
• IP20 Protection Rating: IP20 confirms protection against solid objects larger than 12.5mm (fingers and tools) but no liquid ingress protection. This is a standard data center enclosure rating — appropriate for climate-controlled indoor environments, not for outdoor or high-humidity applications. If your install location has condensation risk or wet conditions, IP20 is not sufficient.
• REACH / PEEP / EOLI Certifications: The AR3387 carries REACH (EU chemical compliance), PEEP, and EOLI certifications. These matter for deployments subject to EU RoHS and chemical substance regulations, and for organizations with environmental compliance reporting obligations.
• Integrated Cable Management: Built-in cable management provisions keep power and data runs organized without requiring after-market panels. Pair with a rack PDU and horizontal cable managers for a clean, maintainable installation.
• Castor Wheels Included: Four castors ship with the enclosure for positioning during installation. Lock them down or use the leveling feet for permanent placement — leaving a rack on unlocked castors in a production environment is a seismic and physical security liability.

Integration and Compatibility

The AR3387 is part of APC's NetShelter SX line, which means it is dimensionally compatible with SX-series accessories including roof-mount fan trays, side-mount cable management channels, and modular power distribution units designed for 800mm-wide cabinets. The 48U height and 1,200mm depth accommodate standard network video recorders, servers, patch panels, and managed switches. Square-hole mounting is universal — cage nuts from any supplier will work. If you are deploying in a structured cabling environment with top or bottom entry, verify cable entry knockouts or blanking options before installation, as the AR3387's entry configuration should be confirmed against your room's cable pathway design. For large-scale rack deployments, review the data center infrastructure planning guide before committing to a row layout.

Frequently Asked Questions

Q: What is the maximum static load capacity of the AR3387?

A: The AR3387 is rated at 1,700 kg static load capacity. This refers to the maximum weight the enclosure structure can support when stationary on leveling feet. Rolling load capacity is a separate, lower spec at 272 kg.

Q: Does the AR3387 come with side panels installed?

A: Yes. Side panels are included with the AR3387 and are installed at the factory. They are also removable and individually keyed for physical security.

Q: Is the AR3387 compatible with standard cage-nut hardware?

A: Yes. The AR3387 uses square mounting holes, which accept standard cage-nut hardware used by virtually all server, storage, and networking equipment vendors.

Q: Can the AR3387 be used in outdoor or high-humidity environments?

A: No. The AR3387 carries an IP20 rating, which means it is designed for climate-controlled indoor environments only. It provides no liquid ingress protection. For environments with moisture, condensation, or outdoor exposure, a higher IP-rated enclosure is required.

Q: What mounting rail depth adjustment does the AR3387 support?

A: The AR3387 features adjustable mounting rails within its 1,200mm depth. This accommodates equipment with varying chassis depths without requiring aftermarket rail adapters for most commercial hardware.

Q: Is the AR3387 compliant with EU chemical regulations?

A: Yes. The AR3387 carries REACH certification, confirming compliance with EU chemical substance regulations. It also holds PEEP and EOLI certifications relevant to environmental compliance reporting.

The AR3387 is the enclosure I specify when depth is the primary constraint on a project. At 1,200mm deep with adjustable mounting rails, it handles full-depth blade chassis and rear-patched top-of-rack switches in the same cabinet — configurations that expose the limits of shallower 800mm or 1,000mm racks. The 1,700 kg static load rating also means you rarely hit a structural ceiling before you hit a floor-loading ceiling, which is a more manageable problem to plan around.

Technical Highlights:

• 1,700 kg Static Load: Structural capacity exceeds what most floor loadings will allow in fully populated configurations — design your row layout around slab or raised-floor ratings, not the rack itself.
• 272 kg Rolling Capacity: Enough to reposition a partially loaded rack without disassembly during installation, but not a substitute for a server dolly on a fully populated 48U cabinet.
• IP20 Rating: Confirms this is a purpose-built indoor enclosure — no liquid protection. Appropriate for data centers and IDF closets with controlled environments; the wrong tool for anything else.

Deployment Considerations:

• The 800mm width is correct for environments running structured cabling with side cable managers — but confirm row spacing in your floor plan before delivery, since 800mm-wide rows require more aisle width than 600mm alternatives.
• Castor wheels are rated for rolling, not for permanent floor contact under load. Use leveling feet for the production position and lock the castors — especially in any facility with seismic risk or a strict physical security policy.

The AR3387 is the right enclosure for high-density data center rows and equipment rooms where deep servers, UPS systems, and patch-heavy top-of-rack switching share cabinet space — particularly where a 48U height lets you consolidate what would otherwise be two shorter racks in a space-constrained row.
