Eaton EMI318-10 – Three-Phase Metered Rack PDU 5.76kW

Product Overview

The Eaton EMI318-10 three-phase metered rack PDU is designed for data center and network closet deployments needing 3-phase power distribution at a lower amperage than higher-capacity models in the EMI series. As a metered PDU, it gives integrators real-time input load data across 39 outlets, supporting rack PDU installation projects where 3-phase circuits are available but a full 24A or 48A rating is not required. This unit is well suited to server rooms and network closets standardizing on 120/208V 3-phase infrastructure with moderate power demands.

Product Description

The Eaton EMI318-10 is a 3-phase, metered input rack PDU rated for 120/208V input at 16A, delivering up to 5.76 kW of usable power. It provides 39 total outlets: 30 IEC 60320 C13, 6 IEC 60320 C19, and 3 NEMA 5-20R receptacles, offering a versatile mix suited to servers, network switches, and equipment using either IEC or standard NEMA power cords. Input connects through a NEMA L21-20P plug on a 10-foot cord, a 3-phase wye connector rated for lower amperage circuits than the L21-30P found on higher-capacity EMI models. A local display combined with Ethernet and RS-232 connectivity gives facilities and IT staff both on-site and remote visibility into input load, which is useful for confirming proper phase balancing during rack PDU installation. The lower 16A rating makes the EMI318-10 an appropriate choice for cabinets where 3-phase infrastructure is present but overall power draw is moderate, such as network closets, government facility equipment rooms, and smaller data center cabinets that do not require the higher-capacity 24A EMI310-10. The 0U vertical mounting profile runs the height of a standard 42U-class rack enclosure, keeping all 39 outlets accessible without consuming horizontal rack unit space. Integrators specifying this PDU should confirm the facility supports 120/208V 3-phase wye service and the L21-20P connector, and should plan equipment distribution across the PDU's phases to keep the load reasonably balanced.

Key Features

• 39-Outlet Mixed Configuration — 30 C13, 6 C19, and 3 NEMA 5-20R outlets support a wide mix of servers, switches, and NEMA-corded equipment on one PDU.
• 3-Phase 5.76 kW Capacity at 16A — A lower-amperage 3-phase input suits cabinets with moderate power demands on existing 3-phase infrastructure.
• Local and Remote Metering — A local display plus Ethernet and RS-232 connectivity provide both on-site and network-based load visibility.
• 0U Vertical Mounting — The PDU installs along the rack frame, preserving rack unit space in standard 42U-class enclosures.
• NEMA L21-20P Input Plug — A standard 3-phase wye connector suited to lower-amperage circuits than higher-capacity EMI models.
• 3-Year Limited Warranty — Backed by Eaton's standard rack PDU warranty.

Typical Applications

• Data center
• Server room
• Network closet
• Government space

Frequently Asked Questions

What electrical circuit does the EMI318-10 require?

It requires a 120/208V, 3-phase wye circuit rated for 16A, terminated with a NEMA L21-20P receptacle. Confirm this matches your facility's available electrical service before ordering.

How does the EMI318-10 differ from the higher-capacity EMI310-10?

Both are 3-phase, 120/208V metered PDUs, but the EMI318-10 is rated for 16A and 5.76 kW with an L21-20P input, while the EMI310-10 is rated for 24A and 8.64 kW with a higher-capacity L21-30P input. Choose based on your circuit's available amperage.

What equipment can connect to this PDU's outlets?

The 39-outlet mix of 30 C13, 6 C19, and 3 NEMA 5-20R receptacles supports IEC-terminated servers and network gear alongside equipment using standard NEMA power cords.

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 EMI318-10 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 EMI318-10 is covered by Eaton's standard 3-year limited warranty. Contact Eaton or Creation Networks for full terms.

Can Creation Networks help determine if the EMI318-10 or EMI310-10 is the right fit?

Yes. Creation Networks can review your facility's available circuit amperage and equipment load to recommend whether the 16A EMI318-10 or the higher-capacity 24A EMI310-10 is the better match for your rack PDU installation.
