APC by Schneider Electric Netshelter SX 48U 600MM Wide X 1200MM Deep Enclosure - AR3307SP

APC by Schneider Electric AR3307SP NetShelter SX 48U 600mm Wide x 1200mm Deep Freestanding Rack Enclosure

Overview

The AR3307SP is APC by Schneider Electric's NetShelter SX 48U freestanding rack enclosure built for data center floors, server rooms, and network equipment deployments where physical density, structural integrity, and access flexibility matter. At 600mm wide and 1200mm deep, it accommodates full-depth enterprise servers, storage arrays, and high-density switching gear without forcing compromises on cable management or airflow. The freestanding, all-metal black frame supports up to 1704 kg — enough headroom for the most loaded 48U configurations you're likely to build. If you're specifying a rack enclosure for an equipment room that needs to grow, this is a practical starting point in the APC by Schneider Electric line.

Key Features

• 48U Capacity — 84U of Vertical Real Estate: With 48U of usable rack space in a single enclosure, you can consolidate a full server, storage, and network stack into one cabinet. That's the difference between one cable run to a top-of-rack switch versus four separate enclosures spread across a row.
• 1704 kg Rated Load Capacity: Most enterprise 2U servers weigh 20–30 kg each. At a 1704 kg structural rating, this enclosure isn't going to be the limiting factor in your rack design — even fully loaded with dense storage or blade chassis hardware.
• 600mm Width — Industry Standard Footprint: The 600mm external width fits standard data center floor tile grids (typically 600mm centers) and matches the form factor used by the majority of enterprise equipment, so you're not burning extra floor space or fighting non-standard cable pathways.
• 1200mm Depth — Full-Depth Server Clearance: Modern enterprise servers and storage nodes routinely hit 750–900mm in chassis depth, plus cables. The 1200mm interior depth gives you real working room — front-to-rear cabling doesn't require gymnastics, and you'll have space behind the equipment for proper vertical cable management.
• Keyed Lock Security: Physical key lock on the enclosure means equipment access is controlled at the cabinet level — relevant for co-location environments, branch offices, or any site where not everyone with physical access to the room should have access to the hardware.
• All-Metal Construction: The metal frame and panels provide structural rigidity and RF shielding. Metal construction also means the enclosure won't warp or settle under sustained load the way composite alternatives can over multi-year deployments.
• UL 60950 / RoHS / REACH Certified: UL 60950 certification covers the safety of IT equipment enclosures — relevant for insurance requirements and facilities compliance in commercial and institutional deployments. RoHS and REACH compliance supports procurement requirements in regulated industries and EU-market installations.
• Removable Side Panels: Side panels ship with the enclosure, providing enclosed equipment protection during normal operation while allowing side access when you need to reach cable trays or perform maintenance without pulling the enclosure out of row.

Integration & Compatibility

The AR3307SP follows EIA-310 19-inch rack standards, which means any equipment designed for standard 19-inch rack mounting — servers, switches, patch panels, UPS units, KVM drawers — installs without adapters or modification. The 1200mm depth accommodates full-depth rack-mount UPS units from APC's Smart-UPS and Symmetra families, which is relevant if you're also specifying uninterruptible power supplies for the same equipment room. If you're building out a complete infrastructure stack, pair this enclosure with compatible PoE switches or structured cabling components to fill the rack efficiently. APC's NetShelter SX accessory line — including side panels, roof sections, blanking panels, and containment components — is designed to bolt directly into this enclosure family, giving you a documented path for expanding containment or adding accessories without custom fabrication.

The AR3307SP is the enclosure I'd specify when the equipment list is long and the budget for re-racking in two years is zero. The 1704 kg structural rating isn't marketing padding — at 48U with a mix of 2U servers, blade chassis, and top-of-rack switching, you can realistically push 600–800 kg of hardware before you're anywhere near the structural limit. That headroom matters when procurement cycles don't align with rack buildout phases.

Technical Highlights:

• 1704 kg Load Rating: At roughly 20–30 kg per 2U server, this enclosure handles 50+ server nodes before structural load becomes a concern — relevant for high-density compute rows where racks get built out in phases over 12–18 months.
• 1200mm Interior Depth: Full-depth enterprise servers (Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem) with rear cable dress typically require 900–1000mm of clearance. The 1200mm depth provides genuine rear cable management space rather than forcing cables into the airflow path.
• UL 60950 + RoHS/REACH Compliance: UL 60950 satisfies facilities and insurance requirements in commercial construction; RoHS/REACH compliance covers EU procurement mandates and regulated-industry purchasing requirements without requiring exemption documentation.

Deployment Considerations:

• Shipping weight is 272.6 kg with package dimensions of 1105mm x 1320.8mm x 2450mm — confirm freight elevator and doorway clearances before delivery. This is not a two-person lift job; plan for a pallet jack and at least three people for positioning.
• The 600mm external width matches standard 600mm floor tile grids, but verify your raised floor or concrete pad layout accounts for the 1200mm depth footprint plus rear access clearance (minimum 900mm is typical for two-person rear maintenance access).

This enclosure is a strong fit for enterprise server room buildouts and co-location deployments where physical security (keyed lock), structural load headroom, and long-term accessory compatibility within the NetShelter SX ecosystem are explicit requirements.
