Eaton EMA333-10

Overview

The Eaton EMA333-10 is a managed three-phase power distribution unit designed to deliver reliable rack-level power to servers, networking equipment, and storage arrays. It supports up to 8.64 kilowatts at 120/208 volts and 24 amps through a NEMA L21-30P input, making it suitable for high-density data center environments. With 28 outlets including 21 IEC C13, 6 IEC C19, and 1 NEMA 5-20R, it accommodates a wide range of devices from standard 1U servers to power-intensive blade enclosures.

This unit features remote monitoring and control capabilities, allowing administrators to manage power cycling, schedule maintenance shutdowns, and track energy consumption at the outlet level. Its 0U vertical form factor mounts alongside equipment without using valuable rack space, and the 10-foot power cord provides flexibility in positioning within racks.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
