Vertiv VP4N62A3 Monitored Unit-Level Horizontal PDU
Overview
The VP4N62A3 is a horizontal, unit-level monitored power distribution unit rated at 60A with a 277/480V WYE three-phase input and 39.8KW total capacity. It is built for high-density data center rows and colocation cabinets where per-outlet monitoring is required to track actual load distribution across a rack — not just inlet-level current. With 24 Saf-D-Grid Series 400 outlets and a 277V output, this PDU is matched to high-voltage cabinet deployments where standard 120/208V PDUs hit their limits. The horizontal form factor means it mounts cleanly in a 1U or 2U rack position rather than consuming vertical rail space, which matters in fully populated 42U enclosures. At 31 lbs and 17.1 in wide × 3.4 in tall × 12 in deep, it fits standard 19-inch EIA rack profiles.
Compatibility
The VP4N62A3 is designed for use with Vertiv's Vertiv power infrastructure ecosystem, specifically cabinet deployments requiring high-voltage three-phase distribution. The 24 Saf-D-Grid Series 400 outlets are compatible with Anderson Saf-D-Grid locking connectors — confirm that your downstream power distribution and IT equipment power cords terminate in Saf-D-Grid Series 400 connectors before ordering. This outlet type is common in high-density AI compute, GPU cluster, and hyperscale server rows where per-outlet amperage tracking is operationally critical. Input feed must supply a 60A, 277/480V WYE three-phase circuit — verify your facility's electrical infrastructure supports this voltage class, as it is not interchangeable with standard 208V three-phase deployments.
Installation Notes
This unit requires a 60A, 277/480V WYE three-phase feed — coordinate with a licensed electrician for the upstream circuit, as 480V infrastructure demands different breaker, conduit, and grounding standards than 208V racks. The horizontal orientation requires standard 19-inch rack mounting; confirm available 1U or 2U clearance in the target cabinet. At 31 lbs, two-person installation is advisable when inserting into a populated rack. Route input whip to a dedicated 60A breaker — do not share the upstream circuit with other loads. Review outlet load balance across all 24 Saf-D-Grid positions to avoid overloading any single branch circuit monitored by the unit.
