APC by Schneider Electric Rack PDU 2G Metered-by-outlet Zerou 1 - AP8459EU3

APC by Schneider Electric AP8459EU3 0U Metered-by-Outlet Rack PDU

Overview

The APC by Schneider Electric AP8459EU3 is a zero-rack-unit (0U), vertically mounted, metered-by-outlet rack power distribution unit delivering 24 outlets at 16A/230V via an IEC309 input. Designed for dense rack environments where individual outlet-level visibility is non-negotiable, the AP8459EU3 mounts flush against the side rail of your rack — preserving every horizontal rack unit for active equipment. It ships with a 3-metre input cable, covering the typical distance from a raised-floor PDU or in-row UPS to the rack without extension hardware.

This unit sits within the APC by Schneider Electric Rack PDU 2G Metered-by-Outlet product family — the generation that added per-outlet current metering on top of branch-level monitoring. If you manage rack power distribution across a mixed server and storage environment in a co-location or enterprise data centre, that distinction matters at billing and at troubleshooting time.

Key Features

• Per-Outlet Metering (Current, Power, Voltage): The AP8459EU3 monitors current, power, and voltage at every individual outlet — not just at the input breaker. That means you can see exactly which server or storage shelf is spiking load, identify phantom draw from idle equipment, and produce per-device power reports without a separate power meter on every port. In multi-tenant and chargeback environments, this is the audit trail that spreadsheet estimates cannot replace.
• 24 Outlets (21× C13, 3× C19): The outlet mix reflects real-world rack populations. Twenty-one C13 ports cover 1U and 2U servers, switches, and patch panels. The three C19 ports handle high-draw equipment — dual-PSU storage arrays, high-density compute nodes, or PDUs chained as a secondary distribution tier. You get maximum density without adapters for standard server loads, with headroom for the inevitable power-hungry outlier.
• 16A Maximum Current at 200–230V: At 230V the unit delivers up to 3,680 VA of load capacity on a single 16A IEC309 feed. That covers a fully populated 42U rack of mid-range 1U servers or a mixed rack with several high-draw storage devices — while staying within the per-phase maximums of a typical European 16A circuit. No derating math required on a balanced single-phase feed.
• 0U Vertical Form Factor: Zero-rack-unit vertical mounting means the PDU occupies zero horizontal rack space. In a 42U cabinet already populated with servers, switches, and patch panels, keeping all 42U available for active equipment is a real capacity gain. The vertical form factor also positions outlets evenly across the cabinet height, reducing cable stress and reach at both the top and bottom of the rack.
• IEC309 Input Connector with 3m Cable: The IEC309 (also referred to as CEE 7 industrial) input is the standard feed point for 16A single-phase circuits in European data centres and co-location facilities. The factory-fitted 3-metre cable reaches from floor-level or under-raised-floor power outlets to the top of a standard 2m rack without a cable extension — a minor detail that becomes significant when you are commissioning 20 racks at once.
• LED Indicators: Onboard LED indicators provide at-a-glance local status confirmation without needing to log into a management interface. Useful during initial installation and for rapid visual triage when walking the aisle.
• 50–60 Hz Input Frequency Tolerance: The unit accepts 50 Hz and 60 Hz input, which matters when equipment purchased for European data centres is later redeployed at 60 Hz facilities or when generators in failover scenarios deliver slightly off-nominal frequency.

Integration and Compatibility

The AP8459EU3 belongs to the APC Rack PDU 2G Metered-by-Outlet line and is compatible with standard APC rack mounting brackets designed for 0U vertical PDUs in two-post and four-post open-frame racks as well as enclosed cabinets. The IEC309 input is the European standard 16A feed connector, so confirm your facility's in-row or floor PDU terminations before ordering.

For environments building out a rack and enclosure infrastructure, the 0U form factor integrates into any standard 600mm or 800mm wide cabinet without occupying usable rack space. Pair with a UPS on the upstream feed if runtime continuity is required — the PDU itself provides distribution and metering, not conditioning or battery backup.

If you are planning power budgets for a new deployment, consult the rack power planning guide to size your upstream circuit correctly against the 16A maximum draw of this unit.

Frequently Asked Questions

Q: What is the maximum load capacity of the AP8459EU3?

A: The AP8459EU3 supports a maximum of 16A per phase at 200–230V input, yielding up to 3,680 VA of total load capacity. The maximum input and total output current per phase are both rated at 16A.

Q: What type of input connector does the AP8459EU3 use?

A: It uses an IEC309 input connector with a factory-fitted 3-metre input cable. IEC309 is the standard industrial 16A single-phase connector used in European data centre and co-location environments.

Q: Does the AP8459EU3 monitor individual outlets or only total input load?

A: The AP8459EU3 is a Metered-by-Outlet PDU, meaning it monitors current, power, and voltage at each individual outlet — not just at the branch or input level. This enables per-device power reporting and load isolation without external meters.

Q: How much rack space does the AP8459EU3 occupy?

A: Zero rack units (0U). The AP8459EU3 mounts vertically inside the rack using the side rail, preserving all horizontal rack units for active equipment.

Q: What is the outlet configuration on the AP8459EU3?

A: The unit provides 24 total outlets: 21× IEC C13 and 3× IEC C19. C13 ports suit standard 1U/2U servers and network equipment; C19 ports accommodate higher-draw devices requiring the larger connector format.

Q: What voltage range does the AP8459EU3 support?

A: The AP8459EU3 accepts 200–230V nominal input at 50–60 Hz, with a 230V nominal output — appropriate for European and international data centre facilities operating on this voltage standard.

Ted Perry

The AP8459EU3's per-outlet metering at 16A/230V is the feature that changes how you manage rack power in dense deployments — not just reading total branch draw, but attributing every watt to a specific port. In a 24-outlet rack running mixed server and storage loads, that level of granularity is the difference between a reactive power audit and a live operational dashboard.

Technical Highlights:

• Per-Outlet Monitoring (Current, Power, Voltage): Monitoring at all 24 individual outlets means you can identify load imbalance across C13 and C19 ports in real time, support per-device power chargeback, and catch a failing PSU drawing anomalous current before it becomes a site incident.
• 3,680 VA Load at 16A/230V: On a standard European 16A single-phase circuit, this unit uses the full available capacity — no derating for the input connector type. Size your upstream breaker and in-row PDU feed accordingly; the AP8459EU3 will consume the full circuit under peak load.
• 21× C13 + 3× C19 Outlet Mix: The 3 C19 outlets are positioned for dual-PSU storage arrays or high-density compute that exceed what C13 can safely carry. In a mixed rack, plan your C19 allocation before cabling — retrofitting outlet assignments in a live rack is a scheduled maintenance window.

Deployment Considerations:

• The IEC309 input requires a matching 16A single-phase receptacle in the facility power circuit — confirm your in-row or floor PDU termination type before rack delivery. The 3m factory cable covers most standard raised-floor-to-rack distances, but measure before assuming it reaches your overhead or underfloor distribution point.
• The AP8459EU3 provides metering and distribution only — it does not condition power or provide battery runtime. If upstream power quality or continuity is a concern, place a suitable UPS on the feed circuit before this PDU.

The AP8459EU3 is the right fit for European co-location build-outs and enterprise data hall expansions where per-device power accountability is contractually required or operationally necessary — particularly in high-density racks where a single 16A/230V feed must be managed at the outlet level rather than at the branch.
