HPE P59406-B21 2.8KVA Metered Hybrid PDU

The HPE P59406-B21 is a 2.8KVA metered hybrid PDU engineered for North American and Japanese rack deployments where outlet flexibility and mounting versatility matter. Whether you're provisioning a dense server rack or a mixed-load network closet, the P59406-B21 delivers a combination of C13, C19, and 5-20R outlets in a single unit — reducing the need for outlet adapters and simplifying power planning across varied equipment types.

Overview

Designed for single-phase environments (with three-phase support noted in the product family), this PDU targets integrators and IT architects who need a reliable, metered power distribution backbone inside the rack. The 2.8KVA capacity positions it for moderate-density loads — enough headroom for a mix of servers, storage, and networking gear without oversizing the power chain. The P59406-B21 (often searched as P59406 B21) is sourced factory-new from HPE's commercial product line.

Key Features

• C13/C19 Hybrid Combo Outlets: Supporting both C13 and C19 receptacles in a hybrid configuration alongside 5-20R NEMA outlets, this PDU eliminates outlet-type mismatches that force last-minute adapter sourcing during rack build-out. Mixed server/storage environments — where some gear ships with C14 plugs and high-draw components use C20 — connect directly without pigtail adapters cluttering cable management.
• 0U Vertical + 1U Horizontal Mounting: The dual mounting option is a practical rack-space lever. Deploy vertically in a 0U configuration to preserve all 42U of usable rack space, or mount horizontally in 1U when vertical rail space is occupied. This flexibility is particularly useful in colocation or edge deployments where rack real estate varies by cabinet.
• Single/Three Phase Power Distribution: Single-phase operation suits standard North American 120V/208V circuits. The noted three-phase support (verify circuit availability at your site) allows load balancing across phases in three-phase-fed cabinets, reducing the risk of phase imbalance that can trip upstream breakers in high-density rows.
• North American and Japanese Market Compatibility (NA/JP): The NA/JP designation means this unit is rated and certified for both North American and Japanese electrical standards — useful for multinational deployments or organizations standardizing on a single SKU across both geographies.

Integration and Compatibility

The C13/C19 hybrid outlet configuration is compatible with the majority of HPE ProLiant, HPE Synergy, and third-party 1U/2U server power supplies shipping C14 and C20 input connectors. The 5-20R NEMA outlets support standard 120V devices, making this PDU practical in mixed IT/facilities environments. Confirm input plug type and circuit breaker rating at the panel before installation — the 2.8KVA rating at the PDU level does not supersede upstream circuit protection requirements.

Frequently Asked Questions

Q: What outlet types does the HPE P59406-B21 include?

A: The P59406-B21 includes C13, C19, and 5-20R NEMA outlets in a C13/C19 hybrid combo configuration, supporting both standard and high-density server power supplies without adapters.

Q: Can the P59406-B21 be mounted both vertically and horizontally?

A: Yes. It supports 0U vertical mounting (preserving full rack unit space) and 1U horizontal mounting, giving you flexibility depending on rack layout and available space.

Q: What is the power capacity of the P59406-B21?

A: The P59406-B21 is rated at 2.8KVA, suitable for moderate-density mixed server and networking loads in a standard rack deployment.

Q: Is the P59406-B21 compatible with Japanese electrical standards?

A: Yes. The NA/JP designation confirms this PDU is rated for both North American and Japanese electrical environments, making it viable for multinational standardization.

Q: Does the P59406-B21 support three-phase power?

A: Single-phase and three-phase power distribution are noted for this product. Verify your site's circuit configuration and consult HPE documentation to confirm three-phase input requirements before provisioning.

The HPE P59406-B21 is one of those PDUs that earns its keep not through headline specs but through practical outlet flexibility. The C13/C19 hybrid combo configuration is the feature I'd highlight first — in mixed-load racks where you have a 1U server on a C14 plug next to a dual-PSU storage array on C20s, having both outlet types on one unit without adapter chains is a real installation win.

Technical Highlights:

• 2.8KVA Capacity: Sized for moderate-density racks — typically 8–12 standard 1U servers at average draw, with headroom for networking gear. Not the right unit for a fully loaded blade chassis, but well-matched to edge or branch deployments.
• Dual Mounting (0U/1U): The 0U vertical option is the preferred deployment in colocation where every rack unit costs money. The 1U horizontal fallback matters when vertical rail space is shared with cable managers or patch panels.
• NA/JP Dual-Market Rating: For organizations with both North American and Japanese data center footprints, a shared SKU simplifies procurement and spare-parts logistics — one part number, two markets.

Deployment Considerations:

• Confirm upstream circuit breaker amperage and input plug type before racking — the 2.8KVA PDU rating does not substitute for proper circuit sizing at the panel level.
• Source data on exact outlet counts per type (C13 vs. C19 vs. 5-20R) from the HPE product sheet before finalizing the rack BOM; the hybrid combo configuration varies by model variant and outlet count drives cabling plans.

Best-fit deployment: a mid-density edge rack or branch IT closet running a mix of HPE ProLiant servers and networking gear on standard 20A circuits, where outlet type variety and rack-space efficiency are the primary constraints.
