Eaton Mini-Power Center P48G28T2124H - NEMA 3R
Part Number: P48G28T2124H
Quick Summary
The Eaton Mini-Power Center provides compact 22.5 kVA three-phase power distribution for data centers and manufacturing panels. Space constraints, installation timelines, and the need for reliable, code-compliant equipment complicate upgrades. This unit carries CSA-certified, UL-listed, and IEEE-certified approvals, with NAFTA compliance for cross-border sourcing. Designed for 480 V input and 208Y/120 V output in a 24-space, wall-mount enclosure, it supports fast installs and scalable expansion. For procurement teams, this translates to predictable lead times, standardized interfaces, and lower total cost of ownership when replacing legacy transformers. In service environments, the aluminum coil and NEMA 3R enclosure deliver robust durability across indoor and outdoor installations.
