APC Netshelter Rack PDU Advanced Metered 11.5KW 3PH 415V 20A 520P6 42 OUT - APDU11250ME

APC by Schneider Electric APDU11250ME Advanced Metered 3-Phase Rack PDU

Overview

The APC by Schneider Electric APDU11250ME is a three-phase, metered rack power distribution unit rated at 11.5kW and 415V, designed for high-density data center racks and network equipment rooms where you need real-time power visibility without deploying a full switched or outlet-monitored PDU. With a 20A maximum current draw and 40 mixed-format AC outlets across four outlet types, this unit handles the power distribution requirements of dense compute, storage, and networking stacks in a zero-U form factor — saving every rack unit for revenue-generating equipment.

The APDU11250ME lands squarely in the rack PDU category for facilities engineers who need three-phase load balancing in European and international 415V environments, managed through the NMC3 network management platform via five onboard RJ-45 Ethernet ports. It is RoHS-compliant and carries UKCA, CE, and EN 62368-1 certifications — making it a straightforward fit for UK and EU deployments subject to those regulatory requirements.

Key Features

• 11.5kW / 11,500 VA Three-Phase Load Capacity: Distributing 11.5kW across three phases means each phase carries roughly 3.8kW of balanced load — flattening the asymmetric draw that single-phase PDUs impose on upstream breakers and UPS systems. In a high-density rack with GPU nodes or blade servers, this phase balance directly reduces risk of nuisance trips.
• 415V / 400V Nominal Input and Output at 50/60 Hz: Rated for both 50 Hz and 60 Hz operation, the APDU11250ME integrates cleanly into European three-phase infrastructure (TN-S or TN-C-S distribution) as well as international facilities running 400V systems. If your site is 208V North American three-phase, this is not the correct model — verify site voltage before ordering.
• 40 AC Outlets Across Four Connector Types (C13, C15, C19, C21): The mixed outlet configuration covers nearly every standard IEC load: C13 for 1U servers and network gear, C15 for higher-temperature equipment (hot-plug PDUs, some UPS bypass loads), C19/C21 for high-current devices drawing up to 16A per outlet. A rack full of mixed equipment types connects without adapter chains or pigtail clutter.
• Metered PDU with NMC3 Management Platform: Metered-level intelligence gives you per-PDU input current and power readings via the APC Schneider Electric NMC3 card — enough to track rack-level load, set threshold alerts, and catch phase imbalances before they become incidents. If you need per-outlet switching or outlet-level metering, step up to the switched or outlet-monitored variants in the NetShelter family.
• 5 x RJ-45 Ethernet Ports: Five network ports on a single PDU supports daisy-chained management across multiple units — useful in multi-PDU racks where you want a single IP management point rather than separate network drops per PDU. This reduces switch port consumption in locked-down data center environments.
• 1 x USB Port: The onboard USB port supports local firmware updates and configuration without requiring network access — relevant during initial commissioning or when performing maintenance in air-gapped environments.
• 0U Rack Footprint (56mm Width): Zero-U mounting keeps the full rack height available for equipment. At 56mm wide, the unit fits standard vertical channel positions in network cabinets and racks without conflicting with adjacent PDU runs on opposite sides of the rack.
• RoHS, UKCA, CE, and EN 62368-1 Certified: Compliance with EN 62368-1 (the audio/video and IT equipment safety standard that superseded EN 60950) means this unit satisfies modern product safety requirements for EU and UK data center procurement. RoHS compliance addresses hazardous substances restrictions for EU market entry. Confirm local regulatory requirements before deploying in non-EU/UK markets.

Integration and Compatibility

The NMC3 management card is compatible with APC's EcoStruxure IT and Data Center Expert platforms for centralized power monitoring across multiple racks and facilities. The APDU11250ME integrates into existing power management software environments that support SNMP, Modbus TCP, or REST API — check your DCIM or EPMS software's NMC3 compatibility list before deployment. The 520P6 input plug type must match your facility's whip or in-row PDU output receptacle; confirm connector compatibility at the panel or upstream distribution point before installation.

Frequently Asked Questions

Q: What input plug does the APDU11250ME use?

A: The APDU11250ME uses a 520P6 input connector, which is a standard IEC three-phase plug used in European and international 415V/400V three-phase distribution. Verify that your facility's power whip or in-row distribution unit has a matching receptacle before installation.

Q: How many outlets does the APDU11250ME have, and what types?

A: The unit provides 40 AC outlets across four IEC connector types: C13 (standard server/networking loads), C15 (higher-temperature-rated loads), C19, and C21 (high-current equipment up to 16A per outlet). The product name references 42 outlets — verify the exact outlet count and mix against the manufacturer's current datasheet for your specific revision.

Q: Is the APDU11250ME compatible with North American 208V three-phase systems?

A: No. The APDU11250ME is rated for 400V/415V three-phase input. It is not suitable for North American 208V three-phase environments. APC offers separate NetShelter PDU models rated for 208V input — select the appropriate model based on your site's distribution voltage.

Q: What management capabilities does the NMC3 platform provide?

A: The NMC3 (Network Management Card 3) provides network-based monitoring of input current, power load, and environmental thresholds. It supports SNMP, Modbus TCP, and REST API protocols and integrates with APC EcoStruxure IT and Data Center Expert platforms for centralized DCIM visibility. This is a metered PDU — it provides input-level measurements, not per-outlet switching or per-outlet metering.

Q: What certifications does the APDU11250ME carry?

A: The APDU11250ME carries UKCA (UK market), CE (EU market), EN 62368-1 (audio/video and IT equipment safety standard), and RoHS (hazardous substances restriction) certifications. These make it compliant for deployment in EU and UK data center environments subject to these regulatory requirements.

Q: Does the APDU11250ME take up rack unit space?

A: No. The APDU11250ME is a 0U device designed to mount vertically in the rack's side channel, preserving all horizontal rack unit space for computing equipment. Its 56mm width fits standard vertical PDU mounting positions in most server rack cabinets.

Karl Wilson

The APDU11250ME is the unit I'd specify for a European colocation build-out where you're running 415V three-phase distribution and need rack-level power visibility without paying for switched or outlet-metered overhead you won't use. The 11.5kW / 20A three-phase rating gives you meaningful headroom in a dense rack — and the five RJ-45 ports on the NMC3 card make daisy-chained management across a multi-PDU cabinet genuinely practical rather than a workaround.

Technical Highlights:

• 40 Mixed-Format IEC Outlets (C13/C15/C19/C21): The four-connector mix means you're not adaptering every high-current device in the rack. C19 and C21 outlets handle 16A draws directly — critical when deploying blade chassis or high-density storage that would saturate a C13 outlet row.
• NMC3 with 5 RJ-45 Ethernet Ports: Five network ports on one PDU means a single IP address can serve an entire multi-PDU rack via daisy chain — fewer switch ports consumed, cleaner cable management, and centralized threshold alerting through EcoStruxure or any SNMP-compatible DCIM platform.
• 0U / 56mm Vertical Form Factor: Zero rack units consumed at 56mm wide. In a 42U cabinet, that's 42U kept available for compute — the PDU disappears into the vertical channel where it belongs.

Deployment Considerations:

• Confirm your upstream distribution panel or in-row PDU has a 520P6 outlet before the unit ships — this is a 415V three-phase connector and mismatched whips are a common commissioning delay on new deployments.
• This is a metered PDU, not switched or outlet-metered. You get input-level current and power readings per PDU, not per outlet. If your operations team needs remote outlet cycling or individual outlet power tracking, you need the switched or outlet-metered variant — don't discover that after rack installation.

The APDU11250ME is the right fit for UK and EU data center racks running 415V three-phase where the facility team wants NMC3 integration into an existing EcoStruxure or SNMP monitoring stack, and outlet-level control is not a requirement. It's a clean, no-overhead metered PDU for environments that already have robust upstream power monitoring and just need reliable in-rack distribution with basic visibility.
