APC by Schneider Electric Netshelter SX 48U 750MM Wide X 1200MM Deep Enclosure - AR3357WX610

APC by Schneider Electric AR3357WX610 NetShelter SX 48U 750mm Wide x 1200mm Deep Server Enclosure

Overview

The APC by Schneider Electric AR3357WX610 is a 48U, 750mm-wide by 1200mm-deep open-frame network enclosure from the APC by Schneider Electric infrastructure lineup — purpose-built for high-density IT and network equipment deployments where cable management, airflow, and structural rigidity matter more than a locked door. At 123 lb (55.79 kg) unloaded, this is a substantial commercial-grade rack that belongs in server rooms, network operations centers, and structured-cabling environments where you're mounting switches, patch panels, UPS units, and compute in the same column.

The 1200mm depth is a deliberate design decision: it accommodates blade servers, deep 2-post-mountable UPS hardware, and full-depth network appliances without the cable-bend compromises you see in 900mm enclosures. The 750mm width gives you standard 19-inch rail space plus meaningful side-clearance for vertical cable managers, which in a high-port-count row makes a real operational difference at 2 AM during a maintenance window.

Key Features

• 48U Usable Rack Space: 48 rack units means you can build a full compute + network + power column in a single enclosure — typical deployments run 20–30U of active equipment with room for 10–15U of structured cable management and a 2U–3U UPS, without stacking a second rack.
• 750mm Width: The 750mm footprint accommodates vertical cable managers on both sides without pulling cables through the rails, which reduces install time and makes future adds or removals dramatically cleaner than a 600mm rack under similar load.
• 1200mm Depth: Full-depth equipment — including blade chassis, deep patch fields, and rear-mounted PDUs — seats correctly without bracket extensions or cable-stress risks. If your environment runs a mix of shallow switches and deep compute, this depth handles both without compromise.
• Commercial-Grade Steel Construction: The NetShelter SX frame is engineered for server rack enclosure environments that see repeated adds/moves/changes. Heavy steel rail construction keeps the rack square under load and provides a secure tap-nut surface for equipment that will be re-mounted multiple times over the enclosure's service life.
• 123 lb (55.79 kg) Unloaded Weight: Factor this into your raised-floor or concrete slab load calculations before you spec the row. A fully loaded 48U rack can exceed 1,500–2,000 lb depending on equipment — confirm structural capacity early, particularly in older facilities or mezzanine-level server rooms.
• Compatibility with APC Power and Cooling Accessories: Designed to accept APC NetShelter SX-series accessories including bolt-on side panels, roof fan trays, and blanking panels — important for maintaining rack PDU and power distribution airflow discipline in high-density rows where hot-aisle/cold-aisle containment matters.

Integration and Compatibility

The AR3357WX610 is compatible with standard 19-inch EIA-310 rack-mount equipment. The 1200mm depth supports both front-mount and mid-mount rail configurations, making it suitable for equipment from major compute and networking vendors. When deploying alongside APC UPS systems, verify rail-kit compatibility for your specific UPS model before ordering — APC publishes rail-kit compatibility by UPS SKU.

For structured cabling installations, this enclosure pairs cleanly with 1U and 2U horizontal cable managers and vertical cable managers mounted to the side channels. In high-density fiber environments, plan vertical manager placement before racking equipment — retroactively routing fiber in a loaded 48U rack is a significant labor cost.

Frequently Asked Questions

Q: What is the usable rack space in the AR3357WX610?

A: The AR3357WX610 provides 48U of usable rack space, sufficient for a full column of compute, networking, and power distribution equipment in a single enclosure.

Q: What are the external dimensions of the AR3357WX610?

A: The enclosure is 750mm wide by 1200mm deep. Height corresponds to a standard 48U rack frame. Confirm exact height-with-casters or height-with-leveling-feet specifications from the APC product datasheet for your facility's ceiling clearance planning.

Q: How much does the AR3357WX610 weigh unloaded?

A: The unloaded weight is 123.00 lb (55.79 kg). Factor this plus your planned equipment load into your floor load calculations before installation.

Q: Is the AR3357WX610 compatible with standard 19-inch rack equipment?

A: Yes. The AR3357WX610 follows the standard EIA-310 19-inch rack specification and accepts standard rack-mount equipment from any vendor using that form factor.

Q: Can the AR3357WX610 accept APC NetShelter SX accessories such as side panels and fan trays?

A: The AR3357WX610 is part of the NetShelter SX family and is designed to accept compatible SX-series accessories including side panels, roof fan trays, and blanking panels. Verify specific accessory compatibility by part number with APC before ordering.

James Everett

The AR3357WX610 is the rack I recommend when the conversation starts with 'we need room for everything in one column.' The 1200mm depth is the spec that earns its place — at that depth you're not compromising on rail position for deep compute, and you're not fighting cable bend radius on rear-mounted PDUs the way you do in a 900mm frame.

Technical Highlights:

• 48U Capacity: A fully built-out 48U column can carry a complete compute-network-power stack for a mid-size server room zone without requiring a second enclosure — that's real floor-space and power-circuit economy in colocation or enterprise edge deployments.
• 750mm Width: The 150mm over a standard 600mm rack isn't cosmetic — it's the difference between a clean vertical cable manager installation and a spaghetti mess. In a structured-cabling environment with 24-port patch panels on every other U, the extra width pays back in every future MAC (move, add, change).
• 123 lb Unloaded Weight: Know this number before the rack arrives on site. On a raised floor, confirm tile and stringer load ratings before positioning. Most enterprise floors handle it, but mezzanine-level or older concrete slabs can be a planning gotcha that bites during commissioning, not before.

Deployment Considerations:

• For hot-aisle/cold-aisle containment, plan blanking panel coverage before powering up — an uncovered 48U frame with gaps will short-circuit your cooling airflow. Order a full set of 1U blanking panels for unused slots at the same time as the enclosure.
• The 1200mm depth requires aisle clearance planning: front service aisle should be at minimum 36 inches, rear aisle 24 inches for safe cable management access. Map this against your room layout before the rack is positioned — repositioning a loaded 48U enclosure is a significant labor event.

The AR3357WX610 is the right call for enterprise server room builds, NOC deployments, and structured-cabling environments where you're planning for density growth over a 5–7 year equipment lifecycle and need a frame that accommodates both current and future equipment depths without a forklift upgrade.
