APC Netshelter Rack PDU Advanced Switched 11.5KW 3PH 415V 20A 520P6 42 OU - APDU11250SW

APC by Schneider Electric APDU11250SW Advanced Switched 3-Phase Rack PDU

Overview

The APC by Schneider Electric APDU11250SW is a high-density, 3-phase switched rack power distribution unit engineered for data centers and enterprise server rooms that demand per-outlet power control at scale. Rated at 11.5kW across a 3-phase 415V input with a 20A draw via a 520P6 inlet, it delivers 42 individually switched outlets — giving power administrators the ability to remotely cycle, sequence, or lock out specific loads without walking the floor. If you manage dense compute racks where a hard reboot requires physical presence, this is the PDU that removes that constraint.

Part of the APC NetShelter line, the APDU11250SW is sized for environments running high-wattage blade servers, storage arrays, or networking infrastructure where granular power management translates directly to reduced downtime and faster incident response.

Key Features

• 11.5kW / 3-Phase 415V Input: handles the power demands of fully loaded compute racks without requiring multiple single-phase circuits — simplifies your electrical infrastructure and reduces the number of PDUs per rack on high-density deployments.
• 42 Switched Outlets: each outlet can be toggled, sequenced, or controlled independently via the network management interface — critical for staged power-on sequencing after a UPS event, or for remotely rebooting a hung server without dispatching a technician.
• 20A / 520P6 Inlet: the IEC 60309 520P6 locking connector provides a secure, vibration-resistant connection to your PDU whip or in-row power source — reduces the risk of accidental disconnection in high-traffic cable environments.
• Advanced Switched Management: the 'Advanced Switched' designation in APC's PDU hierarchy indicates per-outlet switching with remote management capabilities, enabling power scheduling, load monitoring, and outlet-level control through a network interface — reduces unplanned downtime by enabling remote remediation before a site visit is required.
• High Outlet Density (42 outlets): 42 receptacles on a single PDU means fewer distribution devices per rack, less cable management overhead, and a lower per-outlet cost versus deploying multiple lower-density units.
• NetShelter Series Integration: designed to mount inside APC NetShelter enclosures with standard 0U vertical mounting — keeps the PDU out of usable rack unit space, preserving full 42U or 48U capacity for active equipment.

Integration and Compatibility

The APDU11250SW is engineered for integration into APC EcoStruxure-capable environments, where outlet-level power data feeds into broader data center infrastructure management (DCIM) platforms. It is compatible with APC's network management card ecosystem, enabling SNMP, Modbus, and web-based monitoring depending on the installed card. The 520P6 inlet is standard on 3-phase 415V distribution in European and international data center deployments — confirm your local whip or in-row PDU is terminated to match before ordering.

For teams running APC by Schneider Electric infrastructure, this unit integrates natively with EcoStruxure IT for rack power distribution monitoring and alerting. When planning outlet capacity, consult a data center power planning guide to confirm load calculations before specifying PDU wattage. If you need companion uninterruptible power supplies to back this distribution tier, APC's 3-phase UPS lineup is a natural upstream pairing. For high-density deployments where power monitoring granularity matters, also evaluate rack accessories such as environmental sensors that integrate with the same network management card.

Frequently Asked Questions

Q: What input plug does the APDU11250SW use?

A: The APDU11250SW uses a 520P6 inlet — an IEC 60309 5-pin, 20A, 3-phase locking connector rated for 415V. Confirm your in-rack or in-row power whip is terminated with a matching 520P6 receptacle before installation.

Q: How many outlets does the APDU11250SW provide, and are they individually switched?

A: The APDU11250SW provides 42 outlets. As an Advanced Switched PDU, each outlet supports individual remote switching — enabling per-device power cycling, sequencing, and lockout via the network management interface.

Q: What is the total power capacity of the APDU11250SW?

A: The APDU11250SW is rated at 11.5kW total capacity across its 3-phase 415V / 20A input. Plan your connected load to stay within 80% of rated capacity (approximately 9.2kW) per standard data center derated loading practice.

Q: What voltage is the APDU11250SW designed for?

A: The APDU11250SW is designed for 3-phase 415V input, which is standard in European and many international data center environments. It is not intended for North American 208V or 120V single-phase circuits — verify local power infrastructure before specifying.

Q: Does the APDU11250SW fit in a standard 42U rack?

A: The APDU11250SW is part of the APC NetShelter series and is designed for 0U vertical mounting inside APC NetShelter and compatible third-party enclosures, preserving full rack unit space for active equipment.

Marty Allison

The APDU11250SW is one of the more straightforward specification decisions in the APC switched PDU lineup once you confirm your site runs 3-phase 415V — the 520P6 inlet, 11.5kW capacity, and 42 individually switched outlets make it a purpose-built fit for high-density European or international data center racks where per-device remote power control is non-negotiable.

Technical Highlights:

• 42 Switched Outlets: per-outlet control means staged power sequencing after a UPS transfer event — bring up network infrastructure first, then storage, then compute, without manual intervention at the rack.
• 11.5kW 3-Phase Capacity: at 80% derated loading, you have approximately 9.2kW of usable headroom — enough for a fully loaded blade chassis or mixed compute/storage rack without tripping the breaker on cold-start inrush.
• 520P6 Locking Inlet: the IEC 60309 locking connector eliminates the most common cause of unplanned PDU-level outages in active environments — accidental cable pull-out during adjacent maintenance work.

Deployment Considerations:

• The 415V 3-phase input is a hard requirement — this unit will not work on North American 208V or 120V infrastructure; specify the correct APC PDU variant for North American deployments.
• Advanced Switched management requires a compatible APC network management card installed in the PDU's management bay — confirm card availability and firmware compatibility with your DCIM or SNMP monitoring platform before deployment.

The APDU11250SW is best suited for international co-location facilities and enterprise data centers running IEC 60309 power distribution infrastructure, where the combination of 3-phase input, high outlet count, and per-outlet switching eliminates the need for technician dispatches to handle routine remote reboots.
