APC by Schneider Electric AR3300WSP NetShelter SX 42U Rack Enclosure
Overview
The AR3300WSP is APC's NetShelter SX 42U open-frame-style rack enclosure in a 600mm wide by 1200mm deep footprint — the white-finish variant of one of the most widely deployed rack platforms in data center and communications room deployments. At 1991mm tall (78.4 inches), it fits within standard raised-floor and dropped-ceiling envelopes while providing a full 42U of usable mounting space for switches, patch panels, servers, UPS units, and network infrastructure equipment. The AR3300WSP is built to hold it all: the rated static load capacity of 1363 kg (3,005 lbs) means you can fully populate every rack unit with dense blade chassis or high-density PoE switches without approaching the structural limit.
This enclosure carries both REACH and RoHS certifications, making it appropriate for deployments in regulated environments — particularly relevant in EU-facing enterprise projects or government facilities where material compliance documentation is required. The white finish distinguishes it from the standard black NetShelter SX models, which matters in environments like healthcare facilities, clean-room adjacent spaces, or modern open-plan network rooms where aesthetics factor into facilities approval.
Key Features
- 42U Mounting Capacity: A full 42 rack units of vertical space gives you room to run a fully populated switching, patching, and UPS stack without resorting to a second enclosure — reducing your floor footprint and cable run complexity.
- 1363 kg (3,005 lb) Static Load Rating: High-density blade servers, fully loaded PoE switch stacks, and multi-drive NAS appliances routinely approach 150–200 kg per cabinet. The 1363 kg ceiling means this enclosure won't be the limiting factor even in the most aggressively populated switching infrastructure deployments.
- 600mm Width: The 600mm (23.6 inch) exterior width is the most common rack width in enterprise deployments — compatible with standard aisle containment systems, hot/cold aisle spacing guidelines, and raised-floor tile cutouts. Narrower 450mm cabinets restrict airflow options; wider 800mm cabinets waste floor space in most scenarios.
- 1200mm Depth: At 1200mm (47.2 inches) deep, this enclosure accommodates full-depth servers, high-density patch panels with rear cable management, and 1U or 2U network appliances that require rear-to-front airflow clearance. Shallower 800mm or 1000mm enclosures often force compromises on cable routing behind high-density patch fields.
- 1991mm Height (78.4 inches): Fits within standard 2100mm ceiling clearance with room for top-entry cable managers or chimney containment attachments — no custom ceiling modification required in most facilities.
- REACH and RoHS Certified: Material compliance is pre-documented, which accelerates procurement in EU projects and reduces the compliance burden on facilities teams. For integrators working on government or healthcare contracts, having manufacturer-issued REACH/RoHS documentation removes a common procurement bottleneck.
- White Finish: Where standard black racks blend into dark machine rooms, the white finish of the AR3300WSP reads as intentional in bright, open-plan or healthcare environments — useful when the network room is visible to non-technical stakeholders or subject to facilities standards that specify cabinet color.
- Package Dimensions for Logistics Planning: Shipped at 752mm W × 1334mm D × 2118mm H, weighing 149.1 kg — plan for freight delivery (not parcel), a loading dock or lift gate, and at minimum a two-person uncrate. Standard freight elevator minimum dimensions apply; verify door clearance before delivery.
Integration and Compatibility
As a standard 600mm wide, 42U rack enclosure, the AR3300WSP is compatible with APC's full NetShelter SX accessory ecosystem: side panels, blanking panels, vertical cable managers, horizontal cable managers, roof/chimney sections, and PDU mounting brackets. The 1200mm depth accommodates most cable management accessories in the SX line without modification. For UPS and power distribution planning, the 42U space and 1363 kg load rating allow for a combination of rack-mount UPS units, PDUs, and active equipment without structural concerns.
Integrators building out multi-rack rows should note that the white finish is specific to the WSP variant — if you are mixing black AR3300 units with AR3300WSP units in a row, the color contrast will be visible. Order the full row in the same finish variant if visual consistency matters for the installation.
For security integrators deploying NVR-based surveillance infrastructure, the AR3300WSP provides adequate depth and load capacity to house high-channel-count NVRs, PoE switch stacks, patch panels, and associated UPS equipment in a single 42U cabinet — a common consolidation approach in mid-to-large camera deployments.
Frequently Asked Questions
Q: What is the maximum weight the AR3300WSP can hold?
A: The AR3300WSP is rated for a static load capacity of 1363 kg (approximately 3,005 lbs). This covers even the most aggressively populated high-density rack builds.
Q: Is the AR3300WSP RoHS compliant?
A: Yes. The AR3300WSP carries both RoHS and REACH certifications, which is documented at the manufacturer level and useful for EU procurement and regulated-environment deployments.
Q: What are the external dimensions of the AR3300WSP?
A: The enclosure measures 600mm wide (23.6 inches), 1200mm deep (47.2 inches), and 1991mm tall (78.4 inches). Shipped package dimensions are 752mm W × 1334mm D × 2118mm H at 149.1 kg.
Q: How does the AR3300WSP differ from the standard black NetShelter SX?
A: The AR3300WSP is the white-finish variant of the NetShelter SX 42U 600×1200mm enclosure. The specifications — dimensions, load rating, rack unit count — are the same as the equivalent black model. The white finish is intended for environments where color compliance or aesthetics matter, such as healthcare facilities or open-plan network rooms.
Q: What freight considerations apply when receiving the AR3300WSP?
A: The AR3300WSP ships at 149.1 kg in a package measuring 752mm × 1334mm × 2118mm. This requires freight delivery — not standard parcel — and a loading dock or lift gate. Plan for a two-person uncrate minimum, and verify door and elevator clearance before scheduling delivery.
Q: Can the AR3300WSP be used in a security surveillance equipment room?
A: Yes. The 1200mm depth and 1363 kg load rating accommodate NVRs, high-density PoE switch stacks, patch panels, and rack-mount UPS units in a single 42U footprint — a standard approach for mid-to-large camera system infrastructure builds.
The AR3300WSP is the spec I reach for when a project calls for the standard NetShelter SX 42U platform but the facilities team or end-user has a white-cabinet requirement — which comes up more than you'd expect in healthcare IT rooms and modern open-plan network spaces. The 1363 kg static load rating is the number that matters most here: I've never had a fully populated 42U rack approach that ceiling, but it tells you the structural engineering behind this enclosure isn't an afterthought.
Technical Highlights:
- 1363 kg Load Rating: At 3,005 lbs rated capacity, this enclosure handles the heaviest practical rack builds — dense blade chassis, fully loaded PoE switch stacks, multi-drive storage — without the load rating ever becoming a constraint in the design.
- 600mm × 1200mm Footprint: The industry-standard width pairs with 1200mm depth to accommodate full-depth servers and proper rear cable management simultaneously. Shorter-depth enclosures force a cable-versus-equipment tradeoff that this one avoids.
- REACH + RoHS Certification: Both certifications are manufacturer-issued, which matters specifically on government, healthcare, and EU-facing contracts where procurement requires documented material compliance — not just a checkbox claim.
Deployment Considerations:
- At 149.1 kg shipped in a 2118mm tall package, the AR3300WSP is a two-person freight job minimum. Confirm loading dock availability and door/elevator clearance before scheduling delivery — this won't go up a standard stairwell.
- The white finish is specific to the WSP variant. If you are building a multi-cabinet row and mixing with standard black NetShelter SX units, the color mismatch will be visible. Order the full row in the same finish from the start; retrofitting is not practical.
The AR3300WSP is the right call for healthcare IT closets, open-plan network rooms, or any installation where the enclosure color is part of the facilities specification — not just an aesthetic preference. For standard machine room deployments where color doesn't matter, the equivalent black model saves you the variant-sourcing step.
