Eaton Managed PDU, 3PH, 0U, L21-30P Input, 10ft Cord, 8.64kW, 24A, 120/208V, 28 Outlets (21) C13 (6) C19 (1) 5-20R, TAA

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.
