Vertiv 38553 8-Outlet 20A Surge-Protected Rackmount PDU
Overview
The Vertiv VSSL084-102R20 (part number 38553) is a 1U horizontal/vertical rackmount power distribution unit built for IT racks and cabinets that need reliable 20A surge-protected power without the cost of a full metered or switched PDU. At 17 inches wide with eight individually rotated NEMA 5-20R receptacles on a 1.25-inch center-to-center spacing, it fits standard 19-inch panels and makes cable management straightforward in dense 1U installations. This is Vertiv's PowerIT rPDU Basic Surge line — designed for environments that either lack facility-level surge suppression entirely or need a secondary protection layer at the rack itself.
The unit ships TAA-compliant and Buy American Act COTS compliant, which matters for federal, DoD, and government-adjacent deployments where sourcing documentation is part of the bid. Every unit is 100% factory-tested before it ships, so you're not commissioning an untested unit into a production rack.
Key Features
- 720-Joule Surge Protection with Super MOV Technology: 720 joules of energy absorption via Super MOVs catches transient spikes before they reach connected equipment — meaningful in facilities without upstream surge suppression on the utility feed. The 340V maximum clamping voltage is tight enough to protect sensitive 1U servers and network appliances from voltage excursions. A dedicated red LED illuminates if the surge protection degrades, so you know when the unit needs replacement rather than discovering it after a failure event.
- 8x NEMA 5-20R Receptacles, Individually Rotated: Eight 20A-rated outlets at 1.25-inch center-to-center spacing accommodate standard IEC C19/C20 power cords and NEMA 5-20 plugs without the outlet-blocking problem common to tight standard-orientation layouts. Each receptacle is rated for the full 20A circuit — no derating per outlet.
- 20A Thermal Breaker Over-Current Protection: The onboard thermal breaker trips on sustained overcurrent before your upstream panel breaker does, isolating the PDU circuit rather than taking down the broader panel. This is the correct protection approach for a shared 20A branch circuit feeding multiple 1U devices.
- NEMA 5-20P Plug on a 10-Foot, 12/3 AWG Cord: The 10-foot cord on 12 AWG wire gives you enough run to reach a floor-mounted UPS or in-row power tap without an extension, and 12 AWG is appropriately rated for the full 20A draw. Undersized 14 AWG cords on 20A circuits are a common field problem this unit avoids.
- Horizontal and Vertical Rackmount, 17-Inch Chassis: The 17.00 x 1.61 x 1.61-inch chassis installs in a standard 19-inch panel via included mounting brackets, and the 1U profile wastes no rack space. Plastic mounting clips (one top, one bottom) enable vertical zero-U installation on the interior side rail of a cabinet when horizontal rack space is at a premium.
- Green Power-ON LED + Single Input: A single green LED confirms live power at a glance during rack commissioning or post-maintenance verification — simple, unambiguous confirmation without any management overhead.
- 100–120V, 50/60Hz Operation: Works on both 60Hz North American utility power and 50Hz feeds found in some industrial, maritime, or international facility contexts without any adjustment.
- TAA and Buy American Act COTS Compliant, USA Origin: Manufactured in the USA and verified compliant with the Trade Agreements Act and Buy American Act COTS provisions — required documentation for GSA schedules and federal procurement without a waiver.
Integration & Compatibility
The VSSL084-102R20 distributes power to any equipment with a NEMA 5-20R-compatible power inlet — standard on most 1U rack servers, network switches, small UPS bypass panels, and IP surveillance NVR/DVR appliances. It is not a metered or switched PDU; there is no network management port, no per-outlet switching, and no remote monitoring. If your deployment requires outlet-level metering, per-outlet switching, or SNMP/Modbus monitoring, step up to a managed rPDU in the power distribution lineup. For network video recorders and surveillance appliances drawing under 1.9kW aggregate, this unit covers full-rack power distribution in a single 1U slot. Pair it with a Vertiv UPS or power conditioning product upstream if you need runtime backup in addition to surge clamping — this PDU provides surge protection only, not battery backup. For a complete rack power architecture, review the rack PDU selection guide to confirm whether basic surge, metered, or switched fits the monitoring requirements of your deployment.
Frequently Asked Questions
Q: Does the Vertiv 38553 provide battery backup?
A: No. The VSSL084-102R20 is a surge-protected power distribution unit only — it clamps voltage transients up to 720 joules and 340V maximum clamping voltage, but provides no battery backup or UPS functionality. Pair it with a separate UPS upstream for runtime protection.
Q: What is the warranty on the Vertiv 38553?
A: The unit carries a 5-year limited manufacturer warranty. Additionally, Vertiv includes a 5-year / $5,000 Connected Equipment Warranty covering damage to connected equipment resulting from a surge event while the PDU is properly installed.
Q: Is the VSSL084-102R20 TAA compliant?
A: Yes. The 38553 is TAA Compliant, Buy American Act COTS Compliant, and manufactured in the USA — qualifying it for federal and GSA procurement without a domestic-sourcing waiver.
Q: Can the 38553 mount vertically in a cabinet?
A: Yes. The unit supports both horizontal 1U rackmount (via included 19-inch panel mount brackets) and vertical zero-U installation on the interior side of a cabinet using the included plastic mounting clips (one top, one bottom).
Q: How many outlets does the VSSL084-102R20 have and what type?
A: Eight NEMA 5-20R receptacles, individually rotated, rated at 20A / 120V each, with 1.25-inch center-to-center spacing. The input plug is a NEMA 5-20P on a 10-foot, 12/3 AWG power cord.
Q: What certifications does the Vertiv 38553 carry?
A: UL and c-UL Listed to standard 60950, RoHS Compliant, TAA Compliant, and Buy American Act COTS Compliant.
The spec I keep coming back to on the 38553 is the Connected Equipment Warranty — 5 years and $5,000 in coverage for equipment damaged by a surge event while this PDU is in circuit. That's a meaningful backstop for a surveillance or IT rack running NVRs, switches, and servers that would cost far more than the PDU to replace. The VSSL084-102R20 earns its place on the BOM not just as a power strip but as documented surge liability protection.
Technical Highlights:
- 720J / 340V Clamping: Super MOV technology absorbs 720 joules at a 340V clamp level — tight enough to keep sensitive power supplies out of the thermal runaway zone that loose clamping (400V+) allows. The red surge-status LED tells you when the MOVs are spent so you replace before the next event, not after.
- 20A Thermal Breaker: Trips the circuit at the PDU before the upstream panel breaker trips, isolating the rack rather than the whole branch — useful in shared panel environments where a single rack's fault shouldn't black out adjacent circuits.
- TAA + Buy American Act COTS: USA manufacture with verified TAA and BAA COTS compliance means this unit qualifies for federal, DoD, and GSA contracts without exception paperwork — a procurement friction reduction that matters on multi-rack government deployments.
Deployment Considerations:
- The 1.9kW / 20A load ceiling is the aggregate limit across all eight outlets — budget your connected device draw totals before commissioning; a rack full of PoE switches and NVRs can approach this ceiling faster than expected.
- This is a non-managed PDU with no network port, no per-outlet metering, and no remote switching. If your data center or surveillance operations center requires outlet-level visibility or remote reboot capability, this unit is the wrong tier — look at Vertiv's metered or switched rPDU options instead.
For a compact surveillance or edge-IT rack in a government facility, remote field office, or secondary data closet where TAA compliance is required and facility-level surge suppression isn't guaranteed, the 38553 is the right starting point: code-compliant, factory-tested, and covered on both the unit and the connected equipment for five years.
