Power distribution unit APC NetShelter APDU11250SW — 42 AC outlets (C13/C15/C19/C21), 3‑phase, 0U, 400 V, 60 A, NMC3

APC NetShelter APDU11250SW is a 0U rack-mounted, metered and switched power distribution unit (PDU) designed for three-phase IT power distribution. The unit provides 42 AC outlets in four combination types (C13, C15, C19 and C21) within a compact 2.2 in (5.6 cm) width, accepts 400 V nominal input at up to 60 A and operates at 50/60 Hz. Managed via the NMC3 platform and compatible with EcoStruxure IT, this PDU offers remote outlet switching, PDU-level metering with 1% accuracy, and networking via a 1 Gbps Ethernet port. The APDU11250SW includes two link ports for cascading up to 32 PDUs, two environmental sensor ports, and a 3 m input cord with an IEC-309 20 A 3P+N+PE plug. The device is rated to operate at high ambient temperatures and meets multiple international safety and compliance standards including UL, CE, CSA, UKCA and RoHS.

Advantages

The APDU11250SW delivers high outlet density and deployment flexibility through its 4-in-1 combination outlets, allowing a single PDU to power a wide range of IT equipment without requiring multiple adapter types. Integrated metering and switched outlets provide centralized control and visibility of power consumption, enabling load management and proactive overload notification. Network management via NMC3 and support for EcoStruxure IT enable remote configuration, monitoring and integration with data center management workflows. Built-in cascade link ports and network port sharing simplify power management across multiple PDUs, while environmental sensor ports allow for supplemental temperature and humidity monitoring.

Suitable for

• Server racks and data center cabinets with high outlet density requirements
• Network closets and telecom racks requiring mixed outlet types (C13/C15/C19/C21)
• Environments needing remote outlet switching and centralized power metering
• Deployments that require cascading multiple PDUs for shared network/control

How to use

Mount the PDU in a compatible server or network rack in a 0U position and connect the input cord to an appropriate three-phase distribution source rated for the device’s voltage and current. Use the network port to connect the PDU to your management network and configure access through the NMC3 interface, web UI, SNMP, or CLI. Add optional environmental sensors to the sensor ports if temperature or humidity monitoring is required. Use the management interface to view PDU-level power metering, control switched outlets individually or by breaker groups, and configure alert thresholds to receive notifications about load or environmental conditions.

Usage recommendations

Verify the rack and upstream distribution can safely supply three-phase 400 V at the required amperage before installation, and ensure outlet loads are balanced across phases. Use the NMC3 management features and metering to schedule remote outlet cycling, perform controlled reboots, or to isolate circuits for maintenance. Consider cascading PDUs and enabling network port sharing when managing multiple units to centralize network access and reduce cabling complexity.
