Vertiv 13435 30A 3-Phase Basic Rackmount PDU
Overview
The Vertiv PowerIT rPDU 13435 is a 2U horizontal rackmount power distribution unit built for data center racks and dense IT cabinets that require three-phase input with single-phase 120V receptacles. Carrying model number 2XPR183-103D20TL21-SUP, this unit draws 30A at 120/208V WYE from a single NEMA L21-30P twistlock input and distributes it across 18 NEMA 5-20R duplex outlets — the kind of straightforward, high-density power distribution that keeps 1U and 2U servers, network gear, and storage appliances running without requiring intelligent monitoring overhead you don't need. Every unit ships from the USA and is 100% factory-tested before leaving the facility, backed by a 5-year limited warranty.
For integrators and data center engineers evaluating Vertiv power distribution products, the 13435 sits in the Basic Standard tier — no environmental sensors, no per-outlet switching, no network card — just reliable, code-compliant power distribution at a price point that makes sense when you're populating a full row of racks.

Key Features
- 30A Three-Phase WYE Input (L21-30P): The NEMA L21-30P twistlock plug connects to three-phase 120/208V WYE circuits — the standard input for dense rack deployments running off a PDU branch circuit. At 8.6kW continuous load capacity at 120V, you can fill a high-density 1U server rack without hitting the circuit ceiling on typical data center power runs.
- 18x NEMA 5-20R Outlets in 2U: Eighteen standard 20A duplex receptacles wired across three phases (six per phase) means balanced load distribution across the input circuit. Six outlets per phase, three per breaker group, keeps you from cascading a single breaker fault across the entire rack — an important consideration during partial maintenance windows.
- Six 20A Single-Pole Magnetic Breakers + One 30A Triple-Pole: The overcurrent protection scheme is layered: six independent single-pole 20A magnetic breakers cover receptacle groups of three outlets each, while the 30A triple-pole supplementary breaker protects the input. Magnetic breakers reset cleanly without the thermal drift of thermal-magnetic designs, which matters in warm-aisle environments near the operating temperature ceiling of 45°C (113°F).
- 10ft Power Cord with Twistlock Termination: The 10/5 wire gauge cord is long enough to reach overhead PDU whips in most cabinet arrangements without requiring an extension. The L21-30P twistlock locks into the power strip or floor PDU receptacle — no risk of accidental disconnection from cable management pressure or vibration.
- 2U 19-inch Horizontal with Rear-Recessed Mounting: The 19-inch horizontal chassis (3.39in H × 17in W × 6in D, 18 lbs shipped) mounts in a standard 19-inch EIA rack with rear-recess support, keeping the receptacle face flush or set back from the rack rail plane. That 6-inch depth leaves adequate cable egress room in most 1000mm-deep cabinets without blocking rear airflow paths significantly.
- TAA Compliant and Buy American Act COTS Compliant: Manufactured in the USA. TAA compliance satisfies federal procurement requirements for government and government-contractor facilities. COTS compliance under the Buy American Act means this unit can be specified on federal contracts without a domestic content waiver — a hard requirement on GSA schedule and DoD facility projects.
- UL and c-UL Listed (60950), RoHS Compliant: UL 60950 listing covers the information technology equipment safety standard — the correct listing for IT rack PDUs as distinct from general electrical equipment. c-UL covers Canadian installations. RoHS compliance keeps the unit eligible for EU and Canadian procurement programs with restricted substance requirements.
- 5-Year Limited Warranty: Vertiv's standard five-year warranty on this product class is longer than the typical 1–3 year coverage on commodity PDU products. For 7×24 data center environments where replacing a PDU means a maintenance window, that coverage period aligns with a typical equipment refresh cycle.
Integration and Compatibility
The 13435 is a Basic (non-intelligent) PDU — there is no network interface, no SNMP, no per-outlet metering, and no remote switching. It connects to any facility power source wired to a NEMA L21-30P receptacle, which is common on three-phase power strips, floor PDUs, and automatic transfer switches in colocation and enterprise data centers. Compatible with any server rack or cabinet with a standard 19-inch EIA mounting rail and at least 2U of available space. If your project requires per-outlet metering or remote reboot capability, consult the Vertiv Geist metered or switched rPDU families before specifying this unit. For PoE infrastructure planning alongside your power distribution build-out, review the PoE switch selection guide to size upstream network power alongside rack power.
Operating temperature range is 10–45°C (50–113°F) — suitable for hot-aisle/cold-aisle containment environments operating within ASHRAE A1/A2 thermal envelopes. Not rated for ambient temperatures above 45°C; avoid mounting in poorly ventilated enclosures or in rear-door heat exchanger arrangements that trap heat at the PDU mounting position.
Frequently Asked Questions
Q: Is the Vertiv 13435 TAA compliant?
A: Yes. The 13435 is manufactured in the USA and is both TAA Compliant and Buy American Act COTS Compliant, making it eligible for federal and government-contractor procurement without a domestic content waiver.
Q: What is the warranty on the 13435?
A: Vertiv covers the 13435 with a 5-year limited warranty, which is the standard coverage for the PowerIT rPDU Basic line.
Q: What input plug does the 13435 use?
A: The 13435 uses a NEMA L21-30P twistlock plug on a 10-foot, 10/5 AWG power cord. This connects to three-phase 120/208V WYE circuits at 30A per phase — the standard input for this class of rack PDU.
Q: How many outlets does the 13435 have, and what type are they?
A: The 13435 provides 18 NEMA 5-20R duplex receptacles, each rated at 20A maximum output at 120V. Outlets are distributed six per phase, three per single-pole 20A breaker.
Q: Does the 13435 have network monitoring or per-outlet switching?
A: No. The 13435 is a Basic Standard rPDU with no network interface, no SNMP monitoring, no per-outlet metering, and no remote switching. It is a non-intelligent power distribution unit. If remote monitoring or switching is required, Vertiv's metered or switched rPDU models in the same PowerIT family address those requirements.
Q: What safety certifications does the 13435 carry?
A: The 13435 is UL and c-UL Listed to the 60950 standard (information technology equipment safety), and is RoHS compliant. Both the US and Canadian UL listings cover this unit for North American data center installations.
I spec the 13435 specifically for three-phase rack deployments where you need 120V single-phase outlets distributed across all three legs without the cost or complexity of a metered or switched unit. The 30A L21-30P input feeding 18x NEMA 5-20R outlets at 8.6kW load capacity is the right power profile for a fully populated 1U-server rack running ESXi clusters or dense storage nodes — and the six-outlet-per-phase balanced layout means you can load the circuit evenly without manual circuit math.
Technical Highlights:
- Balanced Three-Phase Distribution: Six outlets per phase with three outlets per 20A single-pole breaker — if you lose one breaker group, you lose three outlets on one phase, not the whole rack. That fault isolation is the primary reason to choose this layout over a single-phase PDU on large builds.
- Magnetic Overcurrent Protection: Magnetic breakers (not thermal-magnetic) don't drift with ambient temperature. In a 45°C rear-of-rack environment — which is real in high-density hot-aisle containment — thermal-magnetic trip curves shift unpredictably. Magnetic breakers hold to spec at the thermal ceiling.
- USA Manufacturing + TAA + Buy American COTS: Federal facility projects, DoD sites, and GSA schedule contracts require this. The 13435 clears all three compliance bars out of the box — no domestic content waiver, no procurement exception paperwork.
Deployment Considerations:
- The chassis depth is 6 inches — confirm your cabinet has rear-rail depth and cable management clearance before ordering, particularly in 800mm-deep cabinets where rear cable channels can be tight with the PDU recessed behind the rear rail.
- This is a non-intelligent unit with no network interface. If your operations team expects SNMP trap alerts on circuit overload or remote per-outlet reboot capability, you need a different SKU — the Basic tier does not support it, and there is no field upgrade path to add monitoring.
The 13435 is the right call for colocation customers, federal IT refresh projects, and enterprise data center buildouts running three-phase power infrastructure where per-outlet intelligence isn't in the budget or the requirement — specifically where TAA compliance and UL listing to 60950 are non-negotiable on the procurement checklist.
