APC by Schneider Electric Netshelter SX 45U 600MM Wide X 1070MM Deep Enclosure - AR3105TAA

APC by Schneider Electric AR3105TAA NetShelter SX 45U 600mm Wide x 1070mm Deep Rack Enclosure

Overview

The AR3105TAA is APC's NetShelter SX 45U floor-standing enclosure built for IT rooms, security head-end closets, and government-regulated deployments that require TAA compliance. At 600mm wide and 1070mm deep with a full 45U of usable rack space, it fits the majority of 19-inch rackmount equipment — from NVRs and network switches to servers and UPS units — while meeting federal procurement requirements straight out of the box. The enclosure ships in black and arrives ready to install, with side panels, a key lock, and castor wheels included so you're not sourcing accessories separately before the first device goes in. If your project requires TAA-compliant infrastructure for a government facility, school district, or DoD-adjacent deployment, the AR3105TAA addresses that requirement at the enclosure level rather than forcing a workaround later.

Key Features

• 45U Rack Capacity: 45 rack units gives you enough vertical space to house a full NVR stack, PoE switch layer, patch panels, and UPS in a single cabinet — reducing cable runs between enclosures and simplifying airflow management compared to splitting gear across two shorter racks.
• 600mm Wide x 1070mm Deep Cabinet: The 600mm width is the standard narrow footprint for IT enclosures, fitting comfortably in server rooms and closets that aren't sized for 750mm wide frames. The 1070mm depth (with up to 915mm usable mounting depth) accommodates deep 2U/4U NVR appliances, tower-style UPS units laid on their side, and 1U switches with rear cable management — without the chassis overhanging the rear door.
• TAA Compliance: TAA (Trade Agreements Act) compliance means this enclosure qualifies for GSA Schedule purchases and federal government contracts. If your RFP or bid spec calls for TAA-compliant infrastructure, AR3105TAA checks that box at the cabinet level — no waiver required.
• UL 2416 and UL 60950-1 Certification: UL 2416 is the specific UL standard for IT enclosures, confirming the structure meets tested safety requirements for housing live electrical and networking equipment. UL 60950-1 adds IT equipment safety compliance. Both matter for AHJ (Authority Having Jurisdiction) sign-off on commercial and institutional installations.
• RoHS and REACH Compliance: RoHS restricts hazardous substances in electronic equipment; REACH governs chemical safety in the EU. If your project exports to or operates in EU-regulated environments, or if your sustainability procurement policy requires these, the AR3105TAA qualifies without substitution.
• IP20 Ingress Protection Rating: IP20 is appropriate for controlled indoor environments — it protects against solid objects larger than 12.5mm (fingers, tools) but is not rated against liquids. This is standard for data center and IT room enclosures where environmental controls are in place. Do not deploy this in wet or outdoor environments.
• Side Panels Included: Side panels ship with the enclosure, which matters for both physical security (no open flanks) and airflow containment — side panels are a prerequisite for most hot-aisle/cold-aisle containment setups. You won't need a separate panel kit to close the cabinet out.
• Key Lock: The enclosure includes key locking, providing physical access control to the equipment inside. For facilities that require logged or controlled access to security head-end equipment, this is a baseline physical security measure that doesn't require a separate lock kit purchase.
• Castor Wheels Included: Castors ship with the unit, which is essential during initial positioning — a loaded 45U cabinet is not movable without them. Once positioned, castors typically lock to prevent drift. This saves a separate castor kit order and the delay that comes with it.
• 2124mm Installed Height: At 2124mm (roughly 83.6 inches), the enclosure fits through standard commercial door frames (typically 80–84 inches) with minimal clearance. Measure your route before delivery — this is a common site-prep oversight on 45U cabinets that causes staging delays.

Integration and Compatibility

The AR3105TAA follows the EIA-310 19-inch rack standard, making it compatible with rackmount equipment from any manufacturer — NVRs, network switches, patch panels, KVM units, UPS systems, and cable management accessories. APC's NetShelter SX accessory ecosystem (PDUs, blanking panels, cable managers, airflow kits) integrates directly with this enclosure. The 915mm maximum mounting depth supports the majority of commercial-grade 1U through 4U appliances without modification. For deployments pairing this enclosure with PoE network switches or network video recorders, standard 19-inch rackmount rail kits apply — verify rail compatibility with your specific NVR or appliance vendor before ordering. The enclosure's TAA status aligns with federally procured network infrastructure and access control systems that share the same compliance requirement. For guidance on sizing your rack infrastructure, see the network infrastructure planning guide. Additional APC enclosures and power distribution options are available in the APC by Schneider Electric catalog.

Frequently Asked Questions

Q: Is the AR3105TAA TAA compliant for GSA Schedule and federal government purchases?

A: Yes. The AR3105TAA carries TAA (Trade Agreements Act) compliance, making it eligible for GSA Schedule purchases and federal government contracts that require TAA-compliant infrastructure.

Q: Does the AR3105TAA ship with side panels, or do I need to order them separately?

A: Side panels are included with the AR3105TAA — you do not need a separate panel kit. The enclosure also ships with a key lock and castor wheels included.

Q: What is the usable mounting depth inside the AR3105TAA?

A: The maximum mounting depth is 915mm (91.5cm), which accommodates the majority of commercial-grade 1U through 4U rackmount appliances including deep NVR chassis and UPS units.

Q: Is the AR3105TAA rated for outdoor or wet location use?

A: No. The AR3105TAA carries an IP20 rating, which is suitable for controlled indoor environments only. It is not rated for moisture or liquid ingress and should not be deployed in wet or outdoor locations.

Q: What certifications does the AR3105TAA hold?

A: The AR3105TAA is certified to TAA compliance, UL 2416 (IT enclosures), UL 60950-1 (IT equipment safety), RoHS, and REACH.

Q: Will the AR3105TAA fit through a standard commercial doorway during installation?

A: At 2124mm (approximately 83.6 inches) installed height, the enclosure is at or near the limit of a standard commercial door frame (typically 80–84 inches). Measure your delivery and installation route carefully before the unit arrives — this is a common site-prep issue with 45U cabinets.

Eden Phillips

The AR3105TAA is the NetShelter SX variant I recommend when TAA compliance is a hard requirement and you need a full 45U of space — the 1070mm depth spec is the differentiator here. Most 45U cabinets in this price class top out at 900–950mm internal depth, and that's where you run into trouble with deep 4U NVR chassis or tower-style UPS units mounted horizontally. The 915mm usable mounting depth on the AR3105TAA gives you meaningful clearance for those installations without forcing a shelf or extension rail.

Technical Highlights:

• 915mm Usable Mounting Depth: Accommodates deep 4U NVR appliances and horizontally-mounted tower UPS units without overhang or modification — a real factor in densely-loaded security head-end racks.
• TAA + UL 2416 + UL 60950-1: Three compliance marks that cover federal procurement (TAA), AHJ sign-off on the enclosure structure (UL 2416), and IT equipment safety (UL 60950-1) — all in a single SKU, which simplifies the submittal package on government and institutional projects.
• Included Castors, Panels, and Key Lock: These three accessories are commonly ordered separately and add lead time. Having them in the box means the enclosure is deployable on delivery day, not after a follow-on parts order arrives.

Deployment Considerations:

• At 2124mm installed height, plan your delivery and installation route before the unit ships — doorway clearance is a genuine constraint on 45U cabinets, and a loaded cabinet that won't pass through a corridor is a costly problem to solve on-site.
• IP20 rating means this enclosure is for controlled indoor environments only. If your equipment room has any exposure to condensation, water intrusion, or HVAC drip risk, address those conditions before commissioning — the enclosure provides no liquid protection.

The AR3105TAA is the right call for government, education, and DoD-adjacent security head-end buildouts where TAA compliance is non-negotiable and the equipment list includes at least one deep chassis that a shallower cabinet couldn't close around.
