APC by Schneider Electric Netshelter SX 45U 600MM Wide X 1200MM Deep Enclosure - AR3305SP

APC by Schneider Electric AR3305SP NetShelter SX 45U 600mm × 1200mm Rack Enclosure

Overview

The AR3305SP is APC's NetShelter SX 45U open-frame server enclosure built to the 600mm-wide, 1200mm-deep footprint that has become the de facto standard in structured network rack enclosures for enterprise and data center deployments. At 2,124mm tall (83.6 inches), it accommodates 45 rack units of equipment — enough vertical space to house a full stack of 1U servers, patch panels, and active switching gear without overflow to a second cabinet. If you're specifying a new equipment room or refreshing an aging wiring closet, the AR3305SP gives you a known-good APC platform with the structural ratings and certifications that facilities and compliance teams actually ask for.

The enclosure ships in black and carries UL 2416, UL 60950-1, REACH, RoHS, EOLI, and PEP certifications — a meaningful set for deployments in regulated environments or facilities requiring documented compliance with European environmental directives. The APC by Schneider Electric rack and enclosure line is a frequent choice among IT architects who need a defensible, standards-compliant infrastructure chassis rather than an unbranded import.

Key Features

• 45U Capacity (2,124mm / 83.6 in tall): Forty-five rack units is the practical sweet spot for a single-column deployment — enough to fit a hyperconverged node stack, top-of-rack switching, and structured cabling without the footprint cost of a double-wide open-frame solution. You're not paying for space you won't use on a 52U cabinet, and you're not splitting a stack across two enclosures either.
• 3,005 lb (1,363.64 kg) static weight capacity: Blade chassis, dense storage arrays, and UPS units push the weight envelope fast. This enclosure's static rating accommodates a fully populated high-density load — verify your raised floor or slab rating before you get here, but the enclosure itself won't be the limiting factor in most builds.
• 2,254 lb (1,022.73 kg) rolling weight capacity: Rolling capacity matters during installation and equipment moves. At over a ton rolling, you can populate the enclosure significantly before committing it to a final floor position — useful in phased deployments where racks are pre-staged off-site or in a staging area before being wheeled into the data hall.
• 600mm wide × 1200mm deep footprint: The 600mm width is the narrowest standard footprint that still supports full-depth equipment — you get aisle discipline and row density without the dead air of a 750mm or 800mm wide cabinet. The 1200mm depth accommodates virtually all commercially available 1U–4U servers, network appliances, and blade chassis without depth adapters or rail extensions.
• Adjustable mounting depth — 19.1cm to 104.8cm: Rail positioning adjusts from 191mm to 1,048mm, which means everything from shallow patch panels to deep dual-power-supply rack servers mounts cleanly. You're not forced into fixed-depth rail kits when equipment mix changes between procurement cycles.
• IP20 ingress protection: IP20 means the enclosure provides basic protection against solid objects larger than 12.5mm — appropriate for controlled indoor environments like server rooms, NOCs, and wiring closets. This is not rated for dusty warehouse floors or wet utility spaces; if your installation environment has those conditions, evaluate a higher-IP-rated enclosure before ordering.
• UL 2416 and UL 60950-1 certification: UL 2416 is the specific UL standard for IT rack systems — relevant if your facilities team or insurer requires listed enclosures. UL 60950-1 covers safety of IT equipment, which matters in co-location environments with strict tenant requirements. These listings simplify the facilities approval process in enterprise and institutional installations.
• REACH, RoHS, EOLI, and PEP compliance: The full EU environmental compliance stack. REACH and RoHS matter for any deployment in EU member states or for multinational organizations with EU facilities standards applied globally. PEP (Product Environmental Profile) documentation supports life-cycle assessment requirements increasingly appearing in enterprise procurement RFPs.
• Sides included: The enclosure ships with side panels, providing a degree of cable management discipline and air management compared to open-frame alternatives. Side panels also reduce the risk of accidental contact with energized components in environments without strict access controls.

Integration and Compatibility

The AR3305SP follows the EIA-310 19-inch rack standard, making it compatible with virtually all commercially available rack-mount servers, switches, storage arrays, patch panels, UPS units, and rack-mount KVM switches. The 1200mm depth accommodates full-depth equipment from major server vendors. If you're pairing this enclosure with APC's own power distribution, UPS, or airflow management accessories, the NetShelter SX platform has a mature ecosystem of matching PDUs, blanking panels, and containment kits that integrate directly.

For structured cabling environments, the 600mm width pairs cleanly with standard cable management panels and horizontal organizers. The adjustable rail depth (191–1,048mm) means you can accommodate both shallow networking gear and deep compute nodes in the same enclosure without separate adapter kits.

Security integrators deploying NVR infrastructure, video management servers, or network switching for large-scale physical security systems will find the 45U capacity appropriate for consolidating compute, storage, and networking into a single managed enclosure — reducing the floor space required versus distributed mounting.

A: Yes. The AR3305SP ships with side panels included as noted in the product designation.

James Everett

The AR3305SP is a well-specified 45U enclosure that earns its place in structured deployments primarily because of its weight rating — 1,363.64 kg static is a serious number that covers even high-density blade and storage configurations without requiring a second enclosure or structural consultation on the rack itself. If you're specifying infrastructure for a mid-size enterprise equipment room or a physical security head-end housing NVR servers and managed switching, this is a cabinet you can populate aggressively without hitting a load ceiling early in the asset life.

Technical Highlights:

• 1,363.64 kg static capacity: Covers fully populated blade chassis, dense storage arrays, and UPS units in a single enclosure — you're unlikely to exceed this ceiling in a typical enterprise or security head-end build.
• 191mm–1,048mm adjustable rail depth: Eliminates the need for separate depth adapter kits when mixing shallow patch panels with deep 2U/4U servers; the full adjustment range handles virtually any commercially available rack-mount equipment.
• UL 2416 listed: The rack-specific UL listing (not just a generic electrical safety mark) is the one facilities managers and co-location tenant agreements actually call out by name — having it removes a common procurement friction point.

Deployment Considerations:

• IP20 rating is the watch-out here — this enclosure belongs in a controlled, clean indoor environment. A utility room with active dust or moisture ingress will require a higher-IP-rated enclosure; don't assume IP20 covers light industrial conditions.
• Package weight of 259.4 kg means you'll need a loading dock, pallet jack, and at minimum two-person delivery coordination — factor that into site logistics, especially for upper-floor deployments without freight elevator access.

The AR3305SP is the right call for enterprise equipment rooms, data center co-location rows, and large physical security head-ends where a single high-capacity enclosure consolidates compute, storage, and networking — and where UL listing and EU environmental compliance are non-negotiable on the procurement checklist.
