Vertiv Rpdu Rack Transfer Swch 30A 208V 4.9KW 1 - VA1N3100

Vertiv VA1N3100 Single-Phase Rack Transfer Switch 30A 208V 1U

Overview

The Vertiv VA1N3100 is a single-phase rack transfer switch designed to deliver 30A at 208V (4.9kW capacity) in a 1U horizontal form factor — the right tool when you need a hardwired power path switchover for a rack that cannot tolerate an unplanned outage. This unit plugs in via NEMA L6-30P on the input side and presents a NEMA L6-30R output, keeping the load connection straightforward on standard 30A 208V infrastructure. If you are speccing power redundancy for rack PDU and power distribution deployments, the VA1N3100 sits at the transfer switch layer, not the distribution layer — understand that distinction before you design around it.

Vertiv is one of the more recognized names in data center power and thermal management; you can browse the broader Vertiv power infrastructure catalog to see where this unit fits within their rack power line.

Key Features

• 30A / 208V Input Rating: Supports up to 30 amps at 200–240V single-phase, delivering 4.9kW of switchable load capacity. That headroom covers a fully loaded 2-post or 4-post rack in most edge and colocation environments without derate concerns at typical server draw levels.
• NEMA L6-30P Input / NEMA L6-30R Output: The twist-lock L6-30 family is the de facto standard for 208V 30A circuits in U.S. data centers and server rooms. Matching plug and receptacle types means no adapter chains — wire directly to your PDU branch or panel-fed whip.
• 1U Horizontal 0U-Equivalent Rack Mounting: At 432mm wide × 457mm deep × 44mm tall, the VA1N3100 mounts horizontally in a standard 19-inch rack bay. The 0U designation in Vertiv's taxonomy refers to the unit's efficient use of rack real estate — confirm your available 1U slot clearance and cable management tray clearance at 457mm depth before ordering.
• 3-Meter Input Cable: The factory-attached 3m cord gives you workable reach to a raised-floor PDU or wall-mount panel without needing an extension. Shorter than expected for deep rows — factor in your floor tile or overhead cable path when placing the unit in the rack.
• 50/60 Hz Input Frequency: Dual-frequency acceptance covers both North American 60 Hz grid power and international 50 Hz infrastructure, making the VA1N3100 deployable in global colocation facilities or multinational enterprise sites without a separate SKU.
• Operating Range 0–60°C: The wide thermal envelope handles everything from a well-cooled colocation cage (18–24°C) to a warmer edge closet pushing 45°C+. You won't need to derate or add auxiliary cooling for the transfer switch itself in most real-world rack environments.
• Compact Physical Footprint: At 5.44 kg packaged, this is a one-person install — no lift assist required for standard rack integration. The 432mm width fits standard 19-inch EIA rails without modification.

Integration and Compatibility

The VA1N3100 is a passive transfer switch in Vertiv's Basic PDU tier — it does not carry remote monitoring, network management, or switched outlet intelligence. If your rack infrastructure requires per-outlet metering or remote switching, step up to Vertiv's Monitored or Switched PDU families. This unit is appropriate when you need a clean, low-complexity power transfer path and your monitoring is handled upstream at the panel or UPS level.

For environments building out full rack power redundancy, pair this transfer switch with a compatible UPS or power conditioning unit on each feed. The L6-30 connector family integrates natively with most major UPS bypass and distribution panels in the 208V 30A tier. Consult your facility's circuit breaker coordination study — a 30A transfer switch on a 30A breaker requires careful inrush consideration on simultaneous load transfer.

Frequently Asked Questions

Q: What input plug type does the VA1N3100 use?

A: The VA1N3100 uses a NEMA L6-30P twist-lock input plug on a 3-meter factory-attached cord, designed for 208V 30A single-phase circuits.

Q: What is the output receptacle on the VA1N3100?

A: The output is a NEMA L6-30R receptacle, matching the standard 208V 30A twist-lock family used throughout U.S. data center and server room infrastructure.

Q: Does the VA1N3100 support remote monitoring or network management?

A: No. The VA1N3100 is a Basic-tier transfer switch with no network management, metering, or remote switching capability. Monitoring must be handled upstream at the UPS, panel, or a separate managed PDU layer.

Q: What is the maximum load capacity of the VA1N3100?

A: The VA1N3100 supports a maximum of 30A at 208V, equating to approximately 4.9kW of switchable load capacity on a single-phase circuit.

Q: What rack space does the VA1N3100 require?

A: The VA1N3100 mounts horizontally and occupies 1U (44mm tall) in a standard 19-inch rack bay. The unit is 432mm wide and 457mm deep — verify cable management clearance at that depth in your rack.

Q: Is the VA1N3100 compatible with international 50 Hz power infrastructure?

A: Yes. The VA1N3100 accepts 50 or 60 Hz input frequency across a 200–240V range, making it deployable in both North American and international facilities without a separate model.

Ted Perry

The VA1N3100 is a straightforward 30A 208V single-phase transfer switch from Vertiv's Basic PDU tier — no frills, no management overhead, just a reliable L6-30 input-to-output power path in a 1U horizontal chassis. I reach for this unit when a customer needs path redundancy at the rack level without the cost or complexity of a full managed transfer switch, and the upstream UPS or panel already handles monitoring.

Technical Highlights:

• 30A / 4.9kW Capacity: The 30A rating at 208V covers a typical high-density 1U–2U server rack at real-world draw — you'll rarely see a single rack sustained above 20A in practice, which means the VA1N3100 runs comfortably below its thermal limits.
• NEMA L6-30P/R Connector Pairing: Both sides use the L6-30 twist-lock family, which eliminates adapter risk and keeps the transfer point mechanically secure. Field techs can swap or reseat the connection without tools beyond a quarter-turn.
• 0°C to 60°C Operating Range: That upper limit of 60°C gives meaningful margin for edge deployments in unconditioned or semi-conditioned spaces — industrial closets, remote telecom huts, or edge nodes where HVAC is unreliable.

Deployment Considerations:

• The 457mm depth is on the longer side for a 1U transfer switch — measure your rack's usable depth and confirm the rear cable management tray won't conflict before mounting. Some mid-depth racks (600mm interior) are tight with PDU rails already installed.
• This is a Basic-tier unit with no metering, alerting, or outlet-level switching. If your SLA requires visibility into per-feed current or automatic transfer logging, you need Vertiv's Monitored or Switched transfer switch tier — not this model.

The VA1N3100 is a solid fit for secondary or tertiary racks in a colocation cage where the primary UPS handles all intelligence and you simply need a clean, passive 208V 30A transfer point without adding a managed device to your DCIM inventory.
