Hpe/en G3 B 1P 3.6KVA HH WW PDU - P59407-B21

HPE P59407-B21 G3 Basic 1-Phase 3.6KVA Half-Height Worldwide PDU

Overview

The HPE P59407-B21 is a Generation 3 Basic (EN) monitored power distribution unit rated at 3.6 kVA, designed for single-phase rack deployments where a compact half-height (HH) form factor and worldwide voltage compatibility are priorities. The "WW" designation means this unit is built to operate across international voltage standards — a practical advantage in global deployments or mixed-voltage data center rows where sourcing a region-specific PDU adds procurement friction.

At 6.60 lbs, the P59407-B21 (often searched as P59407 B21) is light enough for tool-assisted single-person rack installation. The half-height chassis keeps vertical rack space consumption low, leaving room for other zero-U or 1U ancillary equipment in dense configurations.

Key Features

• 3.6 kVA Single-Phase Capacity: Sized for mid-density rack loads — enough headroom for a populated server or network-equipment shelf without over-provisioning a higher-kVA unit that would go largely unused.
• Generation 3 Platform: HPE's G3 PDU line introduces revised monitoring and management firmware over prior generations, maintaining compatibility within HPE rack and power infrastructure ecosystems.
• Half-Height Form Factor: The compact chassis is specifically suited for high-density racks where standard full-size PDUs would compete for limited vertical real estate.
• Worldwide Voltage Compatibility: The WW designation supports international input voltage ranges, making this unit suitable for multi-region deployments or facilities with non-standard utility feeds.
• Basic (EN) Monitoring Tier: The "B" designation places this PDU in the Basic monitoring tier — network-attached for status reporting without the higher cost of outlet-level switching or metering found in HPE's Advanced PDU variants.

Integration & Compatibility

The P59407-B21 is designed for integration within HPE rack environments and is compatible with HPE's power management infrastructure. As part of the HPE power and infrastructure catalog, it pairs with HPE ProLiant and Apollo server platforms as well as third-party rack equipment requiring single-phase rack PDU distribution. Consult HPE's network infrastructure documentation for specific outlet configurations and input connector types before ordering — those specs are not confirmed in available evidence and should be verified against your facility's whip and receptacle standard.

Frequently Asked Questions

Q: What does the "WW" designation mean on the HPE P59407-B21?

A: "WW" stands for Worldwide, indicating the PDU supports international voltage standards. This makes it suitable for global deployments or data centers with non-US utility feeds.

Q: What monitoring tier is the P59407-B21?

A: The "B" in the model name denotes the Basic monitoring tier — the unit is network-attached for status visibility but does not include outlet-level switching or metering found in HPE Advanced PDU variants.

Q: Is this a 0U or 1U PDU?

A: The "HH" designation means half-height. Exact rack unit height should be confirmed against HPE's current product datasheet, but the half-height form factor is designed to minimize vertical rack space consumption.

Q: What is the power capacity of the P59407-B21?

A: The P59407-B21 is rated at 3.6 kVA on a single-phase circuit — appropriate for mid-density rack loads.

Eden Phillips

The HPE P59407-B21 slots into a specific niche in the G3 PDU lineup: 3.6 kVA single-phase capacity in a half-height chassis with worldwide voltage support. That combination is genuinely useful in mixed-density rows where you need power distribution without dedicating full vertical real estate to the PDU itself.

Technical Highlights:

• 3.6 kVA Rating: Appropriate headroom for mid-density single-phase rack loads without over-sizing to a higher-kVA unit that would carry unused capacity and added cost.
• Half-Height Chassis: The HH form factor directly addresses rack density constraints — a full-height PDU in a compact row wastes space that could carry switches, patch panels, or cable management.
• Worldwide Input Compatibility: The WW designation removes the need for region-specific SKU selection in global procurement, simplifying spare-unit stocking for multi-site operations.

Deployment Considerations:

• Verify the input connector type and outlet configuration against your facility's whip standard before ordering — the available evidence does not confirm these details, and a mismatch here is a hard stop on installation day.
• The Basic (B) monitoring tier provides network visibility but not outlet-level control; if remote outlet switching is a requirement, evaluate HPE's Advanced PDU variants in the G3 family instead.

Best fit for international or multi-site HPE rack environments where compact form factor, mid-range capacity, and worldwide voltage flexibility matter more than granular outlet-level power management.
