APC by Schneider Electric AR3347B2 NetShelter SX 48U Network Rack Enclosure
Overview
The AR3347B2 is APC's NetShelter SX Generation 2 networking enclosure — a 48U, 800mm-wide, 1200mm-deep cabinet designed for structured network and server deployments where cable density, airflow management, and long-term scalability matter. At 800mm wide and 1200mm deep, this enclosure provides the physical footprint to house full-depth servers, high-density patch panels, and active networking gear without forcing compromise on cable routing. If you're speccing a mid-to-large network equipment deployment and need a rack that won't become the bottleneck as the cabinet fills up, the NetShelter SX line is worth a close look — particularly for data center rows, IDF closets, and security operations infrastructure.
Key Features
- 48U Capacity: 48 rack units of usable vertical space means you can consolidate switches, patch panels, UPS units, and cable management in a single enclosure — reducing floor footprint and simplifying structured cabling runs across the row.
- 800mm Width: The wider 800mm profile (versus standard 600mm) accommodates side-by-side cable management arms, hot-plug drive sleds, and wider 1U/2U appliances without crowding. Critical in high-density switch deployments where rear-port cabling needs clearance.
- 1200mm Depth: Full 1200mm depth supports the longest enterprise servers and network appliances on the market, eliminating the need for depth extenders or workarounds. Relevant for any deployment mixing standard 1U/2U switches with deeper storage or compute nodes.
- Integrated Cable Management: Built-in cable management provisions reduce strain on port connectors and simplify future moves, adds, and changes — an operational detail that pays dividends over the life of the installation.
- RoHS Compliance: Meets RoHS environmental standards, satisfying procurement requirements for government, education, and enterprise customers with sustainability mandates.
- White Finish: The white colorway suits data center environments, clean rooms, or network operations centers where aesthetics and light reflectivity are part of the facilities spec — a practical differentiator from the standard black NetShelter variants in the APC by Schneider Electric lineup.
Integration & Compatibility
The NetShelter SX platform is designed around compatibility with APC's broader power and UPS ecosystem — including rack-mount UPS units, power distribution units (PDUs), and environmental monitoring modules — allowing the enclosure to grow into a fully managed power and cooling infrastructure over time. The 1200mm depth and 800mm width align with standard EIA-310 rack unit specifications, meaning off-the-shelf rack accessories, blanking panels, and third-party cable managers fit without modification. For security and surveillance infrastructure deployments, this enclosure is well-suited to housing NVRs, network switches, and associated server infrastructure in a purpose-built physical layer.

Frequently Asked Questions
Q: What is the usable rack unit capacity of the AR3347B2?
A: The AR3347B2 NetShelter SX enclosure provides 48U of rack space based on the product specification.
Q: What are the external dimensions of the AR3347B2?
A: The enclosure is 800mm wide and 1200mm deep. Height corresponds to a 48U rack form factor.
Q: Is the AR3347B2 RoHS compliant?
A: Yes, the AR3347B2 carries RoHS compliance certification, meeting EU environmental standards for restricted hazardous substances.
Q: Does the AR3347B2 include cable management?
A: Yes, cable management is included with this enclosure.
Q: What color is the AR3347B2?
A: The AR3347B2 is finished in white, distinguishing it from standard black NetShelter SX variants.
When I spec enclosures for network infrastructure deployments, the 800mm width on the AR3347B2 is the detail that matters most — that extra 200mm over a standard 600mm cabinet is the difference between a clean rear cable plant and a cabling disaster waiting to happen at the next MACs cycle. The AR3347B2 gives you the physical room to do it right the first time.
Technical Highlights:
- 800mm Width: Accommodates cable management arms and wider appliances side-by-side — standard 600mm cabinets routinely force compromises in high-density switch rows that cost more to fix later than the cabinet price difference.
- 1200mm Depth: Covers the full range of enterprise network and server hardware depth without extenders — relevant whenever mixing compute, storage, and active network gear in the same row.
- RoHS Certification: Satisfies procurement compliance requirements for public sector and enterprise customers where environmental certifications are a bid requirement, not an afterthought.
Deployment Considerations:
- Confirm your floor loading and raised-floor tile ratings before deploying a fully populated 48U cabinet at this depth — a fully loaded 1200mm-deep enclosure at 48U is a significant point load.
- Evidence on door configuration, side panels, and locking mechanism for the AR3347B2 is not fully confirmed in available documentation — verify these specifics with the manufacturer datasheet before finalizing the order if those details affect your physical security or airflow design.
The AR3347B2 is well-positioned for security operations centers and enterprise IDF/MDF closets where white aesthetics are specified, cable density is high, and the physical infrastructure needs to scale alongside the network without a cabinet replacement cycle.
