APC by Schneider Electric AR3150SP NetShelter SX 42U Rack Enclosure
The AR3150SP is APC by Schneider Electric's NetShelter SX 42U freestanding rack enclosure built for enterprise-grade deployments where structural integrity, cable management headroom, and long-term equipment access all matter. At 750 mm wide and 1070 mm deep, it accommodates deep network and security infrastructure — from high-port-density switches to multi-bay NVRs — without the clearance compromises you get in shallower cabinets. The black metal construction and key-locking door give it a clean, secure presence in data rooms, IDF closets, and security operations centers alike.
Key Features
- 42U Rack Capacity: 42 rack units of usable space means you can stack an NVR, PoE switches, patch panels, UPS, and access control head-end into a single enclosure without running out of room mid-project. For a surveillance head-end consolidation, that's the difference between one cabinet footprint and two.
- 1704 kg Maximum Weight Capacity: Rated to hold over 3,750 lbs of equipment — this matters when you're loading it with high-density UPS gear, battery modules, or multi-drive NVR chassis that individually tip 50+ lbs. Most competitive enclosures in this form factor rate to 1,360 kg; the AR3150SP's margin gives you room to grow without re-evaluating your floor loading plan.
- 750 mm Width: The wider-than-standard 750 mm frame (vs. the common 600 mm) creates meaningful side clearance for power distribution runs, horizontal cable managers, and airflow baffles. In a network rack environment with lots of patch cables or power whips, that extra 150 mm is frequently the difference between a clean install and a tangled one.
- 1070 mm Depth: Deep-chassis equipment — full-depth servers, large UPS units, and enterprise NVRs — needs at minimum 900 mm of usable depth. At 1070 mm, the AR3150SP comfortably handles 1000 mm chassis with door clearance to spare. Don't spec a shallow cabinet for deep equipment and then wonder why the door won't close.
- 1991 mm Overall Height: The enclosure stands 1991 mm tall, keeping the top of the cabinet under typical 2.1 m ceiling clearances while delivering a full 42U payload. If your ceiling is at exactly 2 m, verify your raised floor or base configuration accounts for any added height.
- Key-Locking Door: Physical access control is enforced at the enclosure level — not an afterthought. In multi-tenant data rooms or shared IDF spaces where badge-level access applies to the room but not the cabinet, the keyed lock is the last line of physical defense for your NVR storage and switch infrastructure.
- UL 60950-1 Certification: UL listing confirms the enclosure meets safety standards for IT equipment housing — relevant for sites where facilities or insurance require listed enclosures, and for AHJ sign-off in commercial and government projects. Also carries RoHS compliance, which matters for government procurement and EU-destination installs.
- Metal Construction: All-metal build provides the structural rigidity required for maximum weight payloads and resists the flex and racking that plastic-paneled enclosures can develop over time under heavy loads.
- Sides Included: Solid side panels ship with this model, providing an enclosed aesthetic and dust ingress reduction compared to open-frame racks. For deployments where the cabinet sits in a non-raised-floor environment with foot traffic nearby, enclosed sides meaningfully reduce particulate accumulation on equipment intakes.
Integration and Compatibility
The AR3150SP accepts standard 19-inch EIA-310 rack equipment, which covers the full range of network video recorders, managed PoE switches, patch panels, and UPS units you're likely to install in a security or IT head-end. The 750 mm width accommodates side-mounted cable managers and PDU brackets without conflicting with standard 19-inch equipment. Verify that any blanking panels, cable managers, or PDU accessories you source are compatible with NetShelter SX mounting rail spacing — APC accessories for the SX family mount directly without adapter hardware.
Frequently Asked Questions
Q: What is the maximum weight the AR3150SP can support?
A: The AR3150SP is rated for a maximum static load of 1,704 kg (approximately 3,756 lbs). This is the total weight of installed equipment the enclosure structure can safely bear.
Q: Does the AR3150SP include side panels?
A: Yes. This model ships with solid side panels included, providing an enclosed cabinet configuration rather than an open-frame rack.
Q: What rack unit height is the AR3150SP?
A: The AR3150SP provides 42U of usable rack space within an overall cabinet height of 1991 mm.
Q: What certifications does the AR3150SP carry?
A: The AR3150SP carries UL 60950-1, RoHS, PEP, and EOLI certifications. UL listing is relevant for commercial AHJ approval and insurance requirements on IT equipment enclosures.
Q: What are the overall dimensions of the AR3150SP?
A: The enclosure measures 750 mm wide x 1070 mm deep x 1991 mm tall. Allow for additional clearance around the cabinet for door swing, airflow, and cable management access.
Q: What color and material is the AR3150SP?
A: Black metal construction throughout.
The AR3150SP is one of the few 42U enclosures in the NetShelter SX line rated to a 1,704 kg static load — that's not a spec I'd skip past. When you're consolidating a surveillance head-end with a multi-bay NVR, a UPS, a high-density PoE switch stack, and a patch field into one cabinet, you can realistically approach 300–400 kg of installed equipment, and the structural margin this enclosure provides means you're not re-engineering your cabinet selection when the customer adds a second NVR chassis two years later.
Technical Highlights:
- 1704 kg Weight Rating: Far exceeds typical enclosure ratings in this class; gives meaningful headroom for UPS battery modules and multi-drive NVR chassis without floor-load recalculation mid-project.
- 750 mm Width: The extra 150 mm over standard 600 mm cabinets provides real working room for horizontal cable managers, side-mounted PDU brackets, and airflow baffles — all of which matter in a populated security head-end.
- 1070 mm Depth: Comfortably handles full-depth 1000 mm chassis (enterprise UPS, rackmount servers) with door clearance remaining — a spec that eliminates the door-won't-close problem common with shallower cabinets spec'd for deep equipment.
Deployment Considerations:
- At 271.2 kg packaged weight, confirm your freight receiving situation before ordering — this ships pallet freight, not parcel, and needs a loading dock or liftgate. Account for this in project scheduling.
- Overall height of 1991 mm is tight in rooms with exactly 2 m ceilings — measure your clearance including any raised floor tile height or base/casters before committing the cabinet to a specific bay position.
The AR3150SP is the right call for a permanent, high-density security operations or IDF installation where you're consolidating NVR, switching, and power infrastructure into a single cabinet and expect the load to grow over the project lifecycle. It's over-specified for a lightweight single-NVR closet install — but in a 64-channel-plus surveillance head-end with redundant UPS and a managed PoE switch stack, the structural and depth margins pay for themselves.
