APC NetShelter SX 42U Server Rack Enclosure 750mm Wide

The APC NetShelter SX 42U 750mm Wide Server Rack Enclosure (AR3340) is a purpose-engineered data center cabinet from Schneider Electric, designed to support high-density compute, storage, and networking deployments where elevated cable volumes demand additional horizontal clearance. The 750mm wide footprint extends the standard NetShelter SX profile to accommodate side-by-side cabling trays, cable managers, and wider switching equipment without compromising internal usable space, making it a preferred chassis in core data center rows and enterprise server rooms.

Built on the proven NetShelter SX architecture, the AR3340 features a fully welded 12-gauge steel frame that delivers structural rigidity under heavy static and dynamic load conditions. The enclosure ships with a split 42U mounting rail system on 19-inch EIA-310-E spacing, supporting tool-less or tooled rail kit installation across a broad range of server, storage, and power distribution equipment. Removable and reversible side panels, a vented top panel, and a perforated split front door (77% open area) combine with a perforated split rear door to enable high-volume front-to-rear airflow management compatible with hot-aisle/cold-aisle containment strategies. Integrated cable access knockouts on top, bottom, and sides provide flexible pathway routing for structured cabling and power whips.

The AR3340 is widely deployed across enterprise IT environments including co-location facilities, financial services data centers, healthcare imaging and HIS infrastructure, and large-scale cloud-adjacent on-premises installations. Its compatibility with the full APC NetShelter accessory ecosystem—including blanking panels, roof-mount fan trays, horizontal and vertical cable managers, and PDU mounting brackets—enables administrators to configure and scale enclosures to precise operational requirements without third-party adaptation.

Ideal for

• High-density blade server and 1U/2U rack server deployments requiring extensive front and rear cable management in enterprise core data centers
• Network aggregation and top-of-rack switching installations where wider 750mm clearance accommodates large-diameter fiber and copper cable bundles alongside active equipment
• Co-location cage builds requiring standardized, lockable enclosures with consistent airflow characteristics for multi-tenant SLA compliance
• Storage area network (SAN) and NAS array racks where large numbers of SAS, FC, or Ethernet cables demand additional lateral routing space beyond 600mm cabinet capacity
• Financial services and healthcare data centers requiring robust steel construction, physical access security via lockable doors, and integration with hot-aisle/cold-aisle containment systems
• Modular data center expansions where uniform NetShelter SX enclosure dimensions enable consistent rack-to-rack alignment and shared overhead or underfloor cable pathway planning
