APC by Schneider Electric Netshelter SX 42U 600MM Wide X 1200MM Deep Enclosure Without - AR3300X609

APC by Schneider Electric AR3300X609 42U NetShelter SX Rack Enclosure

Overview

The APC by Schneider Electric AR3300X609 is a 42U freestanding open-frame rack enclosure in the NetShelter SX line — purpose-built for IT rooms, data closets, and operations centers where you need a high-density, structurally reliable equipment housing without the thermal compromise of a fully enclosed cabinet. At 600mm wide and 1200mm deep, it accommodates modern deep-chassis servers, high-density patch configurations, and surveillance NVR stacks that simply won't fit in a shallow 800mm-depth rack. The sideless design is a deliberate choice here: it maximizes front-to-rear and side-to-side airflow, which matters when you're running dense compute or storage loads that generate sustained heat. If your installation uses in-row or overhead cooling rather than perimeter CRAC units, the open architecture of this enclosure works with your airflow strategy rather than against it.

Key Features

• 42U rack capacity: Forty-two rack units give you enough vertical real estate to house a full mix of 1U and 2U servers, patch panels, KVM switches, and NVR appliances in a single enclosure — reducing floor footprint compared to splitting equipment across two shorter racks.
• 600mm width: The 600mm (23.6-inch) wide footprint accommodates standard 19-inch EIA-310-E rack-mount equipment with proper side clearance for cable routing and airflow lanes. Narrower than 800mm wide alternatives, which is an advantage in tight IDF closets or when rows need tighter spacing.
• 1200mm depth: A 1200mm (47.2-inch) depth handles even the deepest 2-post and 4-post rackmount chassis — including blade server enclosures, full-depth UPS units, and high-density NVR storage appliances — without door interference or front-to-rear cable strain.
• 1704 kg maximum weight capacity: Rated for 1,704 kg (approximately 3,756 lbs) of static load. In practical terms, you are not going to max this out with standard IT equipment; the structural margin means you can fully populate the rack without engineering concern and the enclosure will not flex or rack under load.
• Sideless open-frame construction: The absence of side panels is the right call for high-density deployments using precision or in-row cooling. It also simplifies lateral cable runs between adjacent racks and eliminates the cable management overhead of routing through side-panel knockouts.
• EIA-310-E compliance: Conforms to the EIA-310-E standard for rack dimensions, mounting hole spacing, and structural requirements — meaning any standard 19-inch rack-mount component will mount correctly without shimming, adapter rails, or non-standard hardware.
• UL 60950-1 certification: UL listing under the 60950-1 standard for IT equipment safety covers the enclosure's structural and electrical bonding properties — a baseline requirement for enterprise IT deployments and data center compliance audits.
• RoHS compliance: RoHS certification confirms the enclosure meets EU hazardous-substance restrictions — required for deployments in EU-regulated environments and increasingly expected in enterprise procurement globally.
• Black finish: The black powder-coat finish is the standard for modern data center and server room aesthetics, matching the majority of rack-mount equipment faceplates and reducing visual noise in mixed-vendor environments.

Integration & Compatibility

The AR3300X609 follows EIA-310-E 19-inch rack standards, making it compatible with the full spectrum of rack-mount equipment — switches, patch panels, servers, KVMs, NVRs, and UPS units from any manufacturer that adheres to the same standard. The 1200mm depth accommodates APC's own Smart-UPS and Symmetra UPS platforms, as well as deep-chassis servers from major compute vendors. When building out a surveillance or security operations infrastructure, this enclosure pairs directly with network video recorders, managed PoE network switches, and structured cabling panels in a single organized rack. The sideless design is particularly useful when running high-density rack-mount UPS and power distribution that require unobstructed front-to-rear airflow. For cable management accessories, APC offers horizontal and vertical cable managers designed specifically for the NetShelter SX frame dimensions — verify compatibility by NetShelter SX accessory part numbers. If you are evaluating rack enclosure options across the product family, review the broader rack enclosures category to compare depth, width, and side-panel configurations before specifying.

Frequently Asked Questions

Q: What is the usable rack height of the AR3300X609?

A: The AR3300X609 provides 42U of usable rack space, conforming to EIA-310-E standard rack unit spacing. Total enclosure height is 1991mm (approximately 78.4 inches).

Q: Does the AR3300X609 come with side panels?

A: No. The AR3300X609 is specified as an open-frame enclosure without sides. This is intentional for deployments using in-row or overhead cooling where unobstructed lateral airflow is required. Side panels are available as separate accessories in the NetShelter SX line if needed.

Q: What is the maximum load capacity of the AR3300X609?

A: The AR3300X609 is rated for a maximum static weight capacity of 1,704 kg (approximately 3,756 lbs). This far exceeds the populated weight of any standard IT rack configuration.

Q: Is the AR3300X609 RoHS compliant?

A: Yes. The AR3300X609 carries RoHS certification, confirming it meets EU Restriction of Hazardous Substances requirements. It is also UL 60950-1 listed and EIA-310-E compliant.

Q: What standard rack-mount equipment is compatible with the AR3300X609?

A: Any equipment conforming to the EIA-310-E 19-inch (48.3 cm) rack standard is compatible. This includes servers, NVRs, managed switches, patch panels, KVM units, UPS appliances, and cable management accessories from APC and third-party manufacturers.

Q: What are the shipping dimensions and weight for the AR3300X609?

A: The packaged unit ships at 752mm wide x 1334mm long x 2118mm tall, with a package weight of 149.1 kg.

The AR3300X609 is one of those enclosures that earns its place through structural engineering discipline rather than feature lists. The 1,704 kg load rating on a 42U frame sounds like overkill until you are building out a dense NVR or compute stack and someone asks whether you have margin — you do, by a wide factor. The 1200mm depth is the spec I would highlight first for any integrator spec'ing this for a surveillance operations build: shallow racks force compromises on cable management and chassis selection that compound over the life of the deployment.

Technical Highlights:

• 1200mm depth: Accommodates full-depth rackmount appliances — NVR chassis, blade UPS units, and deep-format storage arrays — without front-door or rear-rail interference. Most 19-inch equipment tops out at 900mm chassis depth, so you have substantial clearance for rear cable dressing.
• 1,704 kg weight rating: Structural headroom that eliminates load-limit calculations during rack population. Fully populated 42U racks with servers and storage typically run 400–700 kg; the enclosure's rating absorbs that with margin to spare.
• EIA-310-E compliance: Standard 19-inch mounting geometry means every rail, shelf, and accessory from the NetShelter SX ecosystem — and from any third-party rack-mount vendor — mounts without adaptation. No shimming, no non-standard hardware.

Deployment Considerations:

• The sideless configuration requires your cooling strategy to account for lateral air paths — this enclosure works best with in-row coolers, overhead cooling, or hot-aisle/cold-aisle containment. Do not install it in an open room and rely on perimeter CRAC units without validating airflow coverage at rack depth.
• At 149.1 kg packaged and 1991mm tall, delivery and positioning require a loading dock and at minimum a two-person install with a proper rack-roll dolly. Confirm doorway and elevator clearances (2118mm packaged height) before scheduling delivery.

The AR3300X609 is the right specification for a purpose-built security operations center rack room or a network closet expansion where depth and load capacity cannot be compromised — specifically where the cooling infrastructure already handles open-frame airflow and the equipment mix includes full-depth appliances that would be constrained in a 1000mm or shallower enclosure.
