APC by Schneider Electric Netshelter SX 42U 750MMX1070MM Deep Encl - AR3150W

APC by Schneider Electric AR3150W 42U Freestanding Rack Enclosure

Overview

The APC by Schneider Electric AR3150W is a 42U freestanding rack enclosure from the NetShelter SX family, built for equipment-dense deployments where structural integrity, airflow discipline, and physical security all matter. At 750 mm wide and 1070 mm deep, the AR3150W accommodates the full-depth servers, dense patch panels, and high-port-count switches that characterize modern security operations centers, enterprise wiring closets, and mid-size data rooms. If you are specifying a rack that will house video management servers, NVRs, or network infrastructure for a large surveillance deployment, this enclosure is sized to handle the workload.

The AR3150W ships in white — relevant if the deployment environment is a clean room, broadcast facility, or any space where aesthetics are part of the spec. For traditional data-center gray, review other variants in the APC NetShelter SX line.

Key Features

• 42U Rack Capacity: Forty-two rack units of usable height means you can populate a full complement of 1U/2U servers, patch panels, cable managers, and PDUs in a single footprint. For a video surveillance deployment running a dedicated VMS server, NVR stack, PoE switch tier, and UPS, 42U is typically the minimum you want before you start splitting systems across two racks.
• 750 mm Width: The extra width over a standard 600 mm rack pays off immediately: wider side clearance for cable routing, easier access to rear panel connectors on full-depth servers, and the ability to run structured cabling vertically along the interior rails without crushing bend radii. If your equipment list includes any wide-body servers or blade chassis, the 750 mm interior is the configuration to specify.
• 1070 mm Interior Depth: Full-depth servers and storage arrays — the kind that host high-channel NVR software or serve as recording servers for enterprise network video recorders — typically run 900–1000 mm deep. The 1070 mm depth accommodates those units with enough rear clearance for power and data cabling, a factor that makes a material difference in cable management quality over the life of the installation.
• IP20 Rated Enclosure: IP20 means protection against solid objects larger than 12 mm — fingers, tools — but no dust or moisture protection. This is an indoor data-room enclosure, not a hardened outdoor cabinet. Plan accordingly: the operating environment needs to be conditioned and clean. If you are deploying in a manufacturing floor or any space with airborne particulates, you need a sealed cabinet rated IP54 or higher.
• Keyed Physical Security: The enclosure includes a key lock, which matters in any deployment where the rack is accessible to personnel who do not have equipment-level authorization. In retail back-offices, school IT closets, or shared server rooms, a keyed enclosure is the minimum physical access control layer before you get to logical credentials.
• RoHS, REACH, PEP, and EOLI Compliance: RoHS compliance means the enclosure meets European restrictions on hazardous substances — relevant if the deployment site has environmental certification requirements or the equipment will eventually need responsible disposal. REACH compliance addresses chemical safety in materials. PEP (Product Environmental Profile) and EOLI (End-of-Life Instructions) documentation supports sustainable procurement programs and lifecycle cost accounting, which many enterprise and government procurement teams now require at the bid stage.
• Freestanding Configuration: As a freestanding rack rather than a wall-mount or open-frame, the AR3150W does not require wall-anchoring for operation, which simplifies installation in leased spaces or raised-floor environments. That said, seismic zones and local building codes may still require floor anchoring — verify with the AHJ before commissioning.

Integration and Compatibility

The AR3150W accepts standard 19-inch (48.3 cm) EIA-310 rack equipment, which covers virtually every enterprise server, switch, patch panel, PoE switch, UPS, and KVM on the market. APC's own line of NetShelter-compatible PDUs, blanking panels, cable managers, and mounting rails integrate directly. If you are building out a surveillance infrastructure stack — VMS application server, storage array, managed PoE switches, and a UPS — this enclosure is designed to accept all of it within a single bay.

The 1070 mm depth is compatible with APC's full range of NetShelter accessories including rail kits designed for deep equipment. Before finalizing the rack BOM, confirm that the specific rail kit for each equipment brand is rated for the AR3150W's 750 mm width variant, as some kits are width-specific. For rack accessories and PDUs, APC publishes compatibility lists by enclosure model.

Frequently Asked Questions

Q: What is the maximum load rating for the AR3150W?

A: The AR3150W has a maximum weight capacity of 1704 kg as specified in the product data. Verify with your structural engineer that the floor loading in the installation space supports this weight plus the enclosure's own mass before fully populating the rack.

Q: Is the AR3150W compatible with standard 19-inch rack equipment?

A: Yes. The AR3150W is built to the 19-inch (48.3 cm) EIA-310 rack standard, which is the universal mounting format for servers, switches, patch panels, PDUs, UPS units, and virtually all other rack-mount equipment.

Q: Does the AR3150W include a door lock?

A: Yes. The enclosure includes a key lock for physical access control.

Q: Is the AR3150W suitable for outdoor or dusty industrial environments?

A: No. The AR3150W is rated IP20, which provides protection against incidental contact with solid objects but no dust or moisture protection. It is designed for indoor, conditioned environments such as data rooms, server rooms, and wiring closets. For industrial or outdoor deployments, a sealed cabinet with an appropriate IP rating is required.

Q: What certifications does the AR3150W carry?

A: The AR3150W is certified RoHS and REACH compliant, and carries PEP (Product Environmental Profile) and EOLI (End-of-Life Instructions) documentation — relevant for sustainable procurement and environmental compliance programs.

Q: What color is the AR3150W?

A: The AR3150W is white. If your deployment requires the standard data-center black finish, check other variants in the APC NetShelter SX family for the equivalent specification in black.

Jerry Tildsen

The AR3150W is one of the wider-format NetShelter SX enclosures I regularly specify for enterprise security infrastructure builds — specifically because the 750 mm internal width and 1070 mm depth combination eliminates the cable management compromises you run into with a standard 600 mm rack when you are running full-depth storage or multiple 48-port PoE switches side by side.

Technical Highlights:

• 42U x 750 mm Width: This combination gives you the vertical density of a full rack with enough interior width to run structured cabling vertically without pinching. In a 20- to 30-camera deployment with a dedicated VMS server, storage array, and switch tier, 42U at 750 mm is the configuration that lets you keep the build clean.
• 1070 mm Depth: At 1070 mm, you have real clearance behind full-depth servers — typically 60–80 mm of rear cable space after equipment is seated. That matters when you are running multiple power redundancy feeds plus data uplinks to each device in the rack.
• IP20 Rating: IP20 is fine for any conditioned server room or wiring closet, but it is explicitly not rated for dust or moisture. Spec the environment before you spec the enclosure — this is an indoor cabinet only.

Deployment Considerations:

• The 1704 kg maximum load rating covers virtually any realistic equipment stack, but the enclosure itself plus a full load can approach significant floor weight per square foot — confirm raised-floor or slab load ratings before commissioning in older buildings.
• The AR3150W ships in white, which is non-standard for most data centers. If the site has a physical security policy requiring color-coded rack identification or if the room uses black enclosures for consistency, order the correct color variant from the NetShelter SX line before the build commences — swapping enclosures post-install is a full re-rack operation.

For enterprise physical security builds — SOC infrastructure, large-site NVR stacks, or multi-switch surveillance LAN cores — the AR3150W's 750 mm x 1070 mm footprint and 42U height make it the right enclosure when you know the equipment BOM will push a standard-depth rack to its limits.
