Vertiv 38607 Metered Surge Vertical Rack PDU — 20A, 120V, 20-Outlet
Overview
The Vertiv 38607 (model VSSBC204-102R20TL) is a vertical metered surge-protected rack power distribution unit rated at 20A, 120V, delivering 1.9kW of capacity across 20 individually rotated NEMA 5-20R receptacles. It is designed for data centers, server rooms, and network closets that lack facility-level surge suppression — or for installations where an additional layer of protection is required between the wall feed and sensitive IT gear.
The unit ships with a 10-foot, 12/3 AWG power cord terminated in a NEMA L5-20P twistlock plug, fits flush in a standard 0U vertical rackmount slot at 66.25 inches tall, and carries a 5-year limited warranty with a $5,000 connected equipment warranty. For environments where you are deploying dense server or network hardware, explore the full Vertiv power distribution lineup to match capacity and monitoring tier to your actual load profile.
Key Features
- 20 x NEMA 5-20R Receptacles at 20A Each: Each outlet is rated to carry the full 20A circuit — no derating surprises when provisioning high-draw 1U servers or network switches. Rotated individual outlet style means cables exit cleanly without fighting adjacent plugs, which matters in tight 0U vertical installations where every inch of cable bend radius counts.
- 720-Joule Surge Protection via Super MOV Technology: The onboard surge suppressor absorbs transient energy up to 720 joules and clamps at a maximum of 340V, keeping downstream equipment below the damage threshold during switching transients or utility spikes. A dedicated red surge indicator LED confirms the protection stage is active — if it goes dark, the MOVs have sacrificed themselves and the unit needs replacement, not just a reset.
- Digital RMS Scrolling Power Meter (±2% Accuracy): The local LED display continuously scrolls real-time amperage (A), voltage (V), watts (W), and power factor (PF) at the aggregate unit level. This ±2% accuracy reading is genuinely useful when deploying or re-homing equipment — you can verify actual draw on the rack before closing a change ticket, without needing a clamp meter or remote SNMP query.
- 20A Thermal Breaker Over-Current Protection: A thermal breaker — not a fuse — means nuisance trips reset without ordering replacement hardware. If the circuit overloads, the breaker opens, you shed load, and you reset. In 24/7 data center environments where replacing fuses requires a maintenance window, this is a real operational advantage.
- NEMA L5-20P Twistlock Input Plug: The twistlock input eliminates accidental disconnection under vibration or cable tension — a legitimate concern in dense rack environments where cable management can impose lateral force on PDU inlets. The 10-foot, 12/3 AWG cord provides adequate slack for routing from a floor-mounted power strip or overhead busway to a mid-cabinet PDU position.
- TAA Compliant, Buy American Act COTS Compliant, USA Manufactured: For federal, state, or DoD deployments with procurement compliance requirements, the 38607 clears TAA and Buy American Act COTS thresholds. UL and c-UL 60950 listing plus RoHS compliance round out the certification stack for North American and Canadian facilities.
- Vertical 0U Form Factor — 66.25in Chassis: At 66.25 x 1.61 x 1.61 inches, this unit mounts vertically in the zero-U space on either side of a standard open-frame or enclosed rack. Three plastic mounting clips (1 bottom, 2 top) provide the mechanical attachment — no tools or cage nuts required for the PDU itself, which simplifies installation in live racks. See rack PDU options for side-by-side capacity comparisons.
- 10–45°C (50–113°F) Continuous Operating Range: The rated thermal envelope covers standard conditioned data center environments as well as warmer network closets or edge deployments without active cooling. If your installation space regularly exceeds 45°C, this unit is out of spec — plan accordingly.
Integration and Compatibility
The VSSBC204-102R20TL connects to any 20A, 120V branch circuit terminated with a NEMA L5-20P twistlock receptacle — standard on most data center floor PDUs, power panels, and UPS output strips rated at 20A. The 20 downstream NEMA 5-20R outlets accept standard North American equipment power cords without adapters. Because monitoring is local-only (no network port, no SNMP, no remote access), this unit fits deployments where simplicity and reliability matter more than remote telemetry. If your rack management strategy requires per-outlet switching or network-accessible metering, step up to Vertiv's switched or networked rPDU families instead.
For installations pairing this PDU with a UPS or uninterruptible power supply, confirm the UPS output circuit is L5-20P twistlock at 20A — not all UPS output panels use the twistlock form factor. The 1.9kW (1,900W) load capacity at 120V corresponds to a maximum continuous draw of roughly 15.8A under the 80% loading rule-of-thumb, so derate accordingly when filling all 20 outlets.
For structured power planning across larger deployments, the PoE and power planning resources on this site cover branch circuit sizing and load balancing strategies that apply equally to PDU-fed rack environments. Pair this unit with appropriate rack enclosures and cabinets that provide the vertical 0U channel for proper mounting.
Frequently Asked Questions
Q: What input plug does the Vertiv 38607 use, and what circuit does it require?
A: The 38607 ships with a 10-foot, 12/3 AWG cord terminated in a NEMA L5-20P twistlock plug. It requires a dedicated 20A, 120V branch circuit with a matching L5-20P twistlock receptacle.
Q: Does the VSSBC204-102R20TL support remote monitoring or SNMP?
A: No. The 38607 provides local monitoring only — a scrolling digital RMS display showing aggregate amperage, voltage, watts, and power factor (±2% accuracy). There is no network port, no SNMP agent, and no remote access capability on this model.
Q: What is the joule rating and clamping voltage of the surge protection?
A: The onboard surge protection is rated at 720 joules using Super MOV technology, with a maximum clamping voltage of 340V. A red LED indicator confirms the surge protection stage is active.
Q: What warranty covers the 38607 and connected equipment?
A: Vertiv provides a 5-year limited warranty on the unit itself. Additionally, there is a 5-year, $5,000 connected equipment warranty covering downstream devices damaged by a surge event that passes through the PDU.
Q: Is the Vertiv 38607 TAA compliant?
A: Yes. The 38607 is manufactured in the USA and is both TAA Compliant and Buy American Act COTS Compliant, making it suitable for federal, state, and DoD procurement requirements. It also carries UL and c-UL 60950 listing and is RoHS Compliant.
Q: How many outlets does the 38607 have, and what type are they?
A: The 38607 provides 20 NEMA 5-20R outlets, each rated at 120V/20A. The outlets are individually rotated in style to ease cable management in vertical rack installations.
The spec that consistently gets overlooked on the 38607 is the connected equipment warranty — $5,000 over 5 years, backed by Vertiv, covering downstream gear that sustains surge damage through the PDU. That is not standard across metered rPDUs in this price bracket, and it changes the risk calculus for deploying this unit in racks housing servers or network equipment you cannot afford to lose to a transient. The 38607 earns its place in deployments where facility-level surge suppression is absent or unreliable.
Technical Highlights:
- 720J / 340V Clamp — Super MOV Stack: The 720-joule absorption rating with a 340V maximum clamping voltage is adequate for standard utility transients and inductive load switching events. The red surge LED is your canary — once it extinguishes, the MOVs are spent and the unit is no longer suppressing, even though it continues to distribute power. Build a quarterly visual inspection into your PM schedule.
- ±2% RMS Meter Accuracy: The scrolling local display reads A, V, W, and PF at ±2% across a full-scale 60Hz sine wave — accurate enough for capacity planning and load verification during equipment moves. This is Level 1 aggregate monitoring, meaning you see the whole unit's draw, not per-outlet data. If you need outlet-level granularity, this is not the right tier.
- 20A Thermal Breaker — Resettable, No Spares Required: A thermal breaker versus a fuse is a meaningful operational distinction in live data center environments. Overload, shed load, reset — no parts, no maintenance window, no waiting on a fuse shipment. The 20A rating means you should target no more than 16A sustained draw (80% rule) across all 20 outlets combined.
Deployment Considerations:
- The L5-20P twistlock input requires a matching panel or UPS output receptacle — verify your feed circuit before ordering. A significant number of returns on vertical metered PDUs trace back to plug-form mismatches discovered on installation day.
- At 66.25 inches and 1.61-inch square cross-section, this unit occupies the full height of most standard 42U cabinets in the vertical 0U channel. Confirm your cabinet's side-rail vertical PDU mounting brackets accommodate this length and cross-section — not all enclosed cabinets ship with compatible vertical mounting hardware.
This unit is the right call for federal and state government server closets, edge data center deployments in buildings without dedicated surge infrastructure, and anywhere a TAA-compliant, USA-manufactured rPDU with a credible connected equipment warranty is a procurement requirement.
