Vertiv 12656 Basic Vertical Rack PDU — 30A 208V Delta, 24-Outlet

Overview

The Vertiv XPB248-103D20TL15 (part number 12656) is a basic-tier, vertically-mounted rack power distribution unit designed for data center and equipment room deployments running 208V three-phase delta circuits. With a 30A feed and 8.6kW of usable capacity distributed across 24 NEMA 6-20R receptacles, this unit is purpose-built for high-density rack environments where per-outlet load management and reliable continuous uptime matter more than remote monitoring. If your rack infrastructure is already metered at the PDU input level and you need a dependable pass-through distribution unit that ships from a USA production facility and satisfies federal procurement requirements, the 12656 belongs on your shortlist.

This is a Vertiv rack PDU from the PowerIT rPDU line — a product family that has been used extensively in enterprise data centers, government facilities, and colocation environments where build quality and compliance documentation are non-negotiable. Every unit exits the factory after 100% functional testing, and the 5-year limited warranty is the longest in the standard rPDU category.

Key Features

• 30A, 208V Delta / 8.6kW capacity: At 8.6kW continuous, this unit comfortably supports a fully populated rack of 1U servers drawing 300–400W each. The three-phase delta input distributes load across phases, reducing the risk of single-phase overload in mixed-equipment racks.
• 24 NEMA 6-20R duplex receptacles: Twenty-four outlets arranged in duplex pairs gives you enough feed points for a full rack without daisy-chaining power strips — a practice that voids most equipment warranties and violates NFPA 70E in commercial facilities. At 8 outlets per breaker/phase combination, load grouping is clear and auditable.
• Three 20A double-pole magnetic breakers: Double-pole magnetic breakers provide both phase conductors simultaneously when a fault condition trips them — important on 208V circuits where a single-pole trip leaves half the voltage live. Magnetic trip mechanisms respond faster than thermal alternatives and don't drift with ambient temperature, which matters in warm equipment rooms.
• NEMA L15-30P twistlock input plug with 10ft cord: The L15-30P twistlock terminates at 30A three-phase delta — matching the standard PDU input for 208V delta infrastructure. The 10ft (10/4 gauge) cord gives you enough reach to a floor-mounted or overhead busway tap without extension cords. The twistlock engagement eliminates accidental disconnection under vibration from CRAC units or raised floor airflow.
• 66.25in vertical chassis (2.0in x 2.0in cross-section): At 66.25 inches, this unit is engineered to mount in standard 42U–48U open-frame racks and cabinets. The toolless mounting hardware supports two center-to-center spacing options — 61.25in and 64.75in — which covers virtually all standard rack rail configurations without adapters. The 2.0in x 2.0in cross-section keeps it flush against the rack's vertical channel without consuming usable U-space.
• Heavy steel powder-coat finish (black): The heavy-gauge steel chassis doesn't flex under the weight of 24 loaded receptacles and their cables. Powder coat is more durable than paint for rack environments where cables are frequently re-routed and the unit sees repeated physical contact.
• TAA Compliant / Buy American Act COTS Compliant — USA origin: Federal, state, and defense contractors subject to FAR and DFARS procurement rules can deploy the 12656 without an exception request. TAA compliance is verified at the country-of-origin level (USA), not just assembly. This is a hard procurement gate on many government bids — confirm with your contracting officer which clause applies.
• RoHS Compliant / UL & c-UL Listed 60950: UL 60950 listing covers the safety standard for information technology equipment power distribution — the certification your AHJ and insurance carrier expect on anything inside a raised-floor data room. c-UL listing extends that coverage to Canadian installations without separate certification.
• 10–45°C operating range: This covers most equipment room environments, including hot-aisle/cold-aisle configurations that run warm aisles at 40°C or higher. It is not rated for outdoor or uncontrolled environments — keep it inside the cabinet or room envelope.
• 5-year limited warranty: Five years is meaningfully longer than the 1–3 year terms common on commodity rPDUs. For a device installed at the back of a rack and rarely touched after commissioning, a longer warranty reduces the risk of replacement cost during the typical 5–7 year rack refresh cycle.
• 17 lb shipped weight: At 17 lbs, two people can install this without a lift — relevant for overhead vertical mounting in tall cabinets. Plan for two installers for the initial bracket attachment.

Integration & Compatibility

The 12656 is a basic rack PDU — no network interface, no environmental monitoring, no remote switching. It integrates into any infrastructure where input-level metering is handled upstream (at the panel, busway tap, or a separately installed monitored PDU in the same rack). If your DCIM or BMS platform expects per-outlet switching or current readings, you'll need a managed or metered variant from the Vertiv PowerIT line instead.

The NEMA 6-20R receptacles accept NEMA 6-20P plugs standard on most 208V rack servers, storage arrays, and networking equipment with dual-corded PSUs. Verify your equipment PSU plug type before ordering — NEMA 5-20P (120V) plugs are physically incompatible with 6-20R receptacles, which is a safety feature, not a limitation. For mixed-voltage racks running both 120V and 208V equipment, you'll need a separate 120V circuit and PDU for the 120V loads.

The 61.25in and 64.75in toolless mounting options cover the two most common vertical rail spacings found in open-frame racks and two-post relay racks. If you're mounting in a four-post cabinet with non-standard rail spacing, measure before ordering. Consult rack and cabinet compatibility resources or the equipment manufacturer's mounting templates.

For installations requiring UPS-backed power upstream of this PDU, pair with a three-phase UPS with a compatible 30A L15-30P output receptacle or a panel feed with appropriate OCPD sizing (typically 40A breaker on a 30A PDU per NEC 210.20 continuous load rules — confirm with your licensed electrician).

Frequently Asked Questions

Q: What is the maximum load I can run on the Vertiv 12656 continuously?

A: The 12656 is rated at 8.6kW at 208V with a 30A three-phase delta input. Per NEC guidelines for continuous loads, plan to run no more than 80% of rated capacity continuously — approximately 6.9kW or 24A. Vertiv's 8.6kW figure is the nameplate rating, not the recommended continuous operating load.

Q: Is the 12656 TAA compliant for federal government procurement?

A: Yes. The 12656 is TAA Compliant and Buy American Act COTS Compliant, with country of origin listed as USA. It is suitable for use on federal contracts subject to FAR 52.225-5 and DFARS 252.225-7021. Confirm the applicable clause with your contracting officer.

Q: Does the 12656 include any monitoring or remote management capabilities?

A: No. The 12656 is a Basic-category rPDU with no network interface, no per-outlet metering, and no remote switching. It distributes power reliably but does not report load data to DCIM platforms. If you need per-outlet current monitoring or remote switching, look at monitored or managed variants in the Vertiv PowerIT rPDU line.

Q: What plug type does the 12656 use, and what is the cord length?

A: The 12656 uses a NEMA L15-30P twistlock plug on a 10-gauge/4-conductor, 10-foot power cord. This plug type is standard for 30A three-phase 208V delta circuits. The twistlock design prevents accidental disconnection.

Q: What is the warranty on the Vertiv 12656?

A: Vertiv covers the 12656 with a 5-year limited warranty — one of the longest in the standard rPDU category.

Q: How many outlets does the 12656 provide, and how are they grouped?

A: The 12656 provides 24 NEMA 6-20R receptacles arranged in duplex pairs. Outlets are grouped 8 per breaker/phase combination across three 20A double-pole magnetic breakers. Each receptacle is rated for up to 20A output at 208V.
