Eaton Specification Sheet - N48M28F3316QCULS55
The 300 kVA rating provides headroom for load growth in busy facilities, reducing the risk of mid-project upsizing. Copper windings minimize I^2R losses, improving efficiency and keeping winding temperatures lower under peak load. This configuration translates into lower energy costs and extended transformer life, making it well-suited for manufacturing lines, data centers, and large facility feeders that demand scalable, reliable power distribution. The unit supports 480 V primary to 208Y/120 V secondary voltages, with taps at +2 at 2.5% FCAN and -4 at 2.5% FCBN to optimize loading and voltage regulation, reducing downstream equipment wear and improving overall system stability. Voltage regulation and thermal performance enhance motor drives and control panels in warehouses, factories, and process plants. The NEMA 3R enclosure and floor-mount design enable versatile indoor or sheltered outdoor installations, while copper windings and 220 °C insulation handle continuous duty in demanding environments. With UL Listed certification and DOE2016 Efficient labeling, procurement, commissioning, and compliance reporting are streamlined, minimizing project risk. The 32 in depth, 66 in height, and 50.5 in width footprint fits constrained spaces, and the 2850 lb weight underscores the importance of proper rigging and site preparation for safe installation. Tap adjustments provide additional load adaptation for evolving facilities and future expansion.

FAQs
Plan for a floor-mounted installation on a solid base, given the unit’s 2850 lb weight and sizable footprint (32 in depth, 66 in height, 50.5 in width). Ensure 480 V service availability, proper clearance for cooling, and secure rigging during placement. The NEMA 3R enclosure supports outdoor or sheltered installs, but refer to site wind loads and protective clearances in the specification sheet.
Yes. The transformer is rated DOE2016 Efficient and UL Listed, aligning with energy codes and safety requirements. Catalog notes reference 10 CFR Part 431 (2016) Efficient, which further supports compliance during audits and procurement. This combination reduces life-cycle energy use and simplifies regulatory reporting for industrial facilities.
Ideal for facility feeders, manufacturing lines, and data centers needing reliable low-voltage distribution. With 480 V primary and 208Y/120 V secondary, it accommodates common industrial distribution schemes. The unit’s efficiency, sound level, and rugged enclosure make it suitable for spaces with space or noise constraints while maintaining regulatory compliance and load flexibility.
Primary voltage is 480 V with secondary 208Y/120 V. Tap sizing is +2 at 2.5% FCAN and -4 at 2.5% FCBN, enabling fine-tuning of voltage regulation under varying load conditions. This supports tighter voltage control for sensitive equipment and helps prevent motor over/under-voltage conditions in mixed-load environments.
Maintenance expectations are driven by a copper-wound design, robust NEMA 3R enclosure, and a 60 Hz, 115 °C rise profile, which together reduce thermal stress and reliability concerns. ROI benefits come from energy savings under DOE2016 efficiency, longer service life due to high-quality insulation, and lower risk of unscheduled outages in critical facilities, contributing to a lower total cost of ownership.
