APC by Schneider Electric AR3340W NetShelter SX 42U Networking Rack Enclosure

Overview

The APC by Schneider Electric AR3340W is a 42U open-frame networking enclosure built for structured network infrastructure deployments where physical depth, load capacity, and cable management all matter. At 750mm wide and 1200mm deep, it accommodates deeper networking and NVR equipment that standard 900mm-deep cabinets cannot properly house — a practical consideration in any enterprise MDF or IDF where high-density switching, patch panels, and storage appliances share the same rack footprint. The white finish suits data center environments and network operations centers where color-coding or aesthetic standards apply. REACH and RoHS certifications confirm the enclosure meets European chemical and hazardous-substance compliance standards, relevant for deployments in regulated facilities or government projects.

Key Features

• 42U Height (1991mm / 78.4"): Forty-two rack units gives you headroom for a full complement of 1U and 2U devices — switches, patch panels, NVRs, KVM units, and cable management accessories — without stacking enclosures or splitting logical systems across cabinets. At just under 2 meters tall, it fits standard raised-floor and open-floor data rooms without ceiling clearance issues.
• 750mm Wide Interior: The 750mm width, versus a standard 600mm rack, opens up side-cable routing channels wide enough for dense bundle runs. If you're managing trunk cables or multiple conduit feeds entering the enclosure, that 150mm difference is the margin between a clean installation and a cable-management nightmare.
• 1200mm Deep (47.2"): Modern high-density switches, NVRs, and storage arrays regularly ship with 700–1000mm chassis depths. The 1200mm interior depth accommodates those devices with cable-bend radius to spare at both the front and rear — no forcing equipment in at an angle or leaving rear cable managers unusable.
• 1363.64 kg Maximum Load Rating: This is a substantial structural rating — enough to support a fully populated rack of server and networking gear without floor-load concerns becoming the limiting factor. For security integrators deploying heavy NVR arrays or video analytics appliances, the load rating removes a constraint that lighter enclosures introduce.
• REACH and RoHS Certified: Both certifications are required for EU-market deployments and are increasingly demanded by US federal and state procurement specs. RoHS restricts hazardous substances in electrical equipment; REACH governs chemical substances in the supply chain. Having both documented on the AR3340W simplifies compliance paperwork in regulated environments.
• White Finish: The white colorway distinguishes this enclosure from standard black equipment racks and is intentional for environments where color-coded infrastructure helps technicians quickly identify network versus power versus AV enclosures in a shared room.
• Includes Side Panels: Side panels ship with this model, which matters for airflow management — open sides create bypass airflow that defeats hot-aisle/cold-aisle containment. Having sides installed from day one means your thermal management strategy isn't compromised before the first device is racked.

Integration and Compatibility

The AR3340W follows standard EIA-310 rack unit spacing, making it compatible with any 19-inch rack-mount equipment. The 1200mm depth accommodates the deepest enterprise networking hardware currently on the market. For security systems integrators, this enclosure suits centralized NVR and VMS server deployments where multiple high-capacity recorders, managed PoE switches, and patch infrastructure are consolidated into a single cabinet. The REACH/RoHS certifications make it compliant for government, education, and healthcare facility deployments where material compliance is a procurement requirement.
