Eaton P48G28T21P Mini-Power Center - NEMA 3R
Part Number: P48G28T21P
Quick Summary
Mini-Power Center by Eaton delivers compact three-phase power distribution for industrial control panels. Engineers often wrestle with space constraints, harsh environments, and complex wiring in panel assemblies. The unit ships with a rugged NEMA 3R enclosure and is IEEE Certified, UL Listed, and CSA Certified, giving reliability across indoor-outdoor locations. With a 22.5 kVA rating, primary 480 V and secondary 208Y/120 V, and a 60 Hz rating, it provides documented performance for modern automation lines. Its aluminum coil, 103A21K wiring, and -5% FCBN tap enable voltage stability while reducing field adjustments. In practice, this translates to faster installs, improved fault tolerance, and lower lifecycle costs for OEMs and integrators.

FAQs
Plan for a footprint of 29.9 in wide x 40.9 in high x 13.6 in deep and a 559 lb weight, which may require forklift handling. Ensure adequate clearance for ventilation, access to wiring (103A21K), and compliance with NEMA 3R outdoor requirements. Use the -5% FCBN tap to optimize voltage if feeders experience drops.
The center provides a 22.5 kVA rating with a 480 V primary and 208Y/120 V secondary, operating at 60 Hz in three-phase configurations. It uses a 2 at -5% FCBN tap and 103A21K wiring, suitable for feeding multiple machine controls and distribution points within a single panel or subpanel system.
Yes. It carries IEEE Certification, UL Listing, ANSI, and CSA Certification, plus a NEMA 3R enclosure for indoor-outdoor use. This combination supports regulatory compliance, safety, and reliability across diverse industrial environments and OEM applications.
Ideal for control panels, machine centers, and panelboards in manufacturing and process industries. Its combination of 480 V to 208Y/120 V output, 22.5 kVA capacity, and rugged enclosure makes it a strong fit for OEMs needing compact transformer centers that can withstand outdoor or harsh indoor conditions.
Leverage its aluminum coil for durability and plan routine inspections of wiring (103A21K) and enclosure seals for NEMA 3R protection. The unit offers a one-year warranty from installation or 18 months from shipment, whichever occurs first, reducing risk and supporting predictable maintenance budgeting.
