Eaton EMI310-10 – Three-Phase Metered Rack PDU 8.64kW

Product Overview

The Eaton EMI310-10 three-phase metered rack PDU is built for data center and colocation cabinet deployments that need higher power density than a single-phase circuit can provide. As a 3-phase metered PDU, it delivers 8.64 kW across 37 outlets while giving integrators real-time input load data for rack PDU installation and ongoing capacity planning. This unit is a common specification for enterprise data centers and colocation facilities consolidating dense server and network loads onto a single 3-phase circuit rather than multiple single-phase PDUs.

Product Description

The Eaton EMI310-10 is a 3-phase, metered input rack PDU rated for 120/208V input at 24A, delivering up to 8.64 kW of usable power. It provides 37 total outlets: 30 IEC 60320 C13, 6 IEC 60320 C19, and 1 NEMA 5-20R receptacle, giving integrators a versatile outlet mix for servers, switches, and network appliances that terminate on either IEC or NEMA power cords. Input connects through a NEMA L21-30P plug on a 10-foot cord, a standard 3-phase wye connector widely used in North American data center electrical infrastructure. A local display and remote monitoring via Ethernet and RS-232 give facilities and IT staff visibility into aggregate input load, supporting proper phase balancing during rack PDU installation. Because power is distributed across three phases rather than a single circuit, the EMI310-10 can support a higher overall load per rack than a comparable single-phase unit of similar outlet count, which is a common requirement in colocation cabinet and enterprise data center deployments consolidating equipment onto fewer, higher-capacity circuits. The 0U vertical mounting profile runs the height of a standard 42U-class rack enclosure, keeping the full 37-outlet count accessible without consuming horizontal rack unit space needed for servers and switches. Integrators specifying this PDU for a data center or colocation cabinet build should confirm the facility supports 120/208V 3-phase wye service and the L21-30P connector, and should plan equipment placement to balance load reasonably evenly across the three phases feeding the unit.

Key Features

• 37-Outlet Mixed Configuration — 30 C13, 6 C19, and 1 NEMA 5-20R outlet accommodate a wide range of servers, switches, and network appliances on one PDU.
• 3-Phase 8.64 kW Capacity — Distributing power across three phases supports a higher overall rack load than a comparable single-phase PDU.
• Local and Remote Metering — A local display plus Ethernet and RS-232 connectivity provide both on-site and network-based visibility into input load.
• 0U Vertical Mounting — The PDU installs along the rack frame, preserving rack unit space for active equipment in standard 42U-class enclosures.
• NEMA L21-30P Input Plug — A standard 3-phase wye connector simplifies electrical planning in facilities with existing 3-phase infrastructure.
• UL Listed and TAA Compliant — Independent certification and trade compliance support commercial and government facility deployments.
• 3-Year Limited Warranty — Backed by Eaton's standard rack PDU warranty.

Typical Applications

• Data center
• Colocation cabinet
• Server room

Frequently Asked Questions

What electrical circuit does the EMI310-10 require?

It requires a 120/208V, 3-phase wye circuit rated for 24A, terminated with a NEMA L21-30P receptacle. Confirm this matches your facility's available electrical service before ordering.

Can I mix IEC and NEMA-corded equipment on this PDU?

Yes. The 37-outlet configuration includes 30 C13, 6 C19, and 1 NEMA 5-20R receptacle, supporting both IEC-terminated servers and equipment that ships with standard NEMA power cords.

Why choose a 3-phase PDU instead of single-phase for this rack?

A 3-phase circuit distributes load across three separate phases, allowing the EMI310-10 to support a higher overall power capacity per rack than a comparable single-phase PDU, which is useful in dense data center and colocation cabinet deployments.

Can this PDU be monitored remotely?

Yes. It includes an Ethernet interface and RS-232 serial port for remote monitoring of input load alongside its local display.

Does the EMI310-10 support individual outlet switching?

No. This is a metered input model, reporting total load without per-outlet control. Eaton's switched or managed PDU models are available where outlet-level control is required.

What warranty does this PDU carry?

The EMI310-10 is covered by Eaton's standard 3-year limited warranty. Contact Eaton or Creation Networks for full terms.

Can Creation Networks help with phase balancing during installation?

Yes. Creation Networks can advise on equipment placement across the PDU's outlets to help balance load evenly across the three phases during rack PDU installation.
