Vertiv VP4NC0A1 Monitored Vertical PDU 100A 277/480V WYE
Overview
The VP4NC0A1 is a unit-level monitored, vertical rack PDU rated at 100A and 277/480V WYE (66.4kW) — purpose-built for high-density data center rows where per-outlet load visibility is required without adding a separate metering layer. At 72 inches long and 3×3 inches in cross-section, this PDU mounts vertically in the rear rail space of standard cabinets, keeping the front and side footprint clear. Its 18 Saf-D-Grid Series 400 outlets support Anderson-style connectors, making it the right choice for deployments that have standardized on Saf-D-Grid high-current distribution — common in colocation, hyperscale, and high-performance compute environments.
Compatibility
Designed for integration with Vertiv power distribution infrastructure and any cabinet or row configuration that accommodates a vertical rack PDU in a standard 2-post or 4-post rear-mount position. The 18-outlet Saf-D-Grid Series 400 output is specifically compatible with Anderson Saf-D-Grid Series 400 connectors — confirm your downstream power whips and receptacles match the Series 400 form factor before ordering. The 277V single-phase output draws from a 277/480V WYE 3-phase source, so your upstream panel or transformer must supply a WYE-configured feed at that voltage; a delta-configured panel is not compatible. For three-phase load balancing across an entire row, pair multiple VP4NC0A1 units — one per phase leg — with a compatible branch circuit distribution panel rated for 277/480V WYE.
Installation Notes
The unit weighs 30 lbs and measures 72 in × 3 in × 3 in — two-person lift recommended for vertical rail installation. Confirm cabinet depth and rear rail clearance accommodate the full 72-inch length before mounting. Input feed is a single 100A circuit; verify the upstream breaker is sized to 80% continuous load (80A) per NEC requirements for continuous loads. Saf-D-Grid connectors require a specialized crimping tool and Series 400-rated whips — standard NEMA wiring does not terminate to this connector family. Monitor integration uses the unit-level measurement architecture; confirm firmware and network management card compatibility with your DCIM platform before deployment.
