Eaton N48D28B12EELS47 Transformer - UL Listed
Part Number: N48D28B12EELS47
Quick Summary
The Eaton K-Factor nonlinear ventilated transformer is designed to supply reliable 3-phase power for 480 V to 208Y/120 V distributions. In tough industrial environments, noise, efficiency losses, and thermal stress threaten uptime and maintenance costs. UL Listed and NEMA TP-1 compliant, with low-sound performance, the design also emphasizes efficiency and regulatory alignment. This 112.5 kVA transformer with 2% taps supports efficient voltage regulation and scalable power distribution for plants. Its aluminum windings, 80 °C rise, and 60 Hz operation align with broad industrial standards, while a 56.17 inch height and 31.44 inch width integrate into tall equipment rooms. For maintenance teams, the 1-year warranty offers peace of mind, while rugged construction supports long service intervals.

Eaton Specification Sheet - N48D28B12EELS47
112.5 kVA three-phase rating provides ample headroom for mid-range loads, reducing overload risk and voltage drop during peak demand. It supports a 480 V primary and 208Y/120 V secondary, enabling plant-wide distribution and panel-board compatibility for manufacturing lines and process controls. The dual taps (+2.5% / -2.5%) improve voltage regulation under fluctuating supply, protecting motors and sensors and lowering lifecycle costs. Low sound (47 dB) and NEMA TP-1 efficient designation reduce acoustic impact and cooling energy, enabling tighter equipment layouts and energy savings in crowded plant rooms. Aluminum windings minimize copper losses and improve heat dissipation, while electrostatic shielding mitigates EMI in complex automation environments. The WS34 weather shield and robust frame support outdoor or harsh-indoor installations with long service life. UL Listed and NEMA TP-1 compliance simplify procurement and regulatory reviews, backed by a one-year warranty (or 18 months from shipment).

FAQs
Yes. This transformer is designed for a 480 V primary and 208Y/120 V secondary, three-phase operation at 60 Hz, making it compatible with common industrial electrical distributions. Its 112.5 kVA rating provides adequate headroom for many mid-scale loads while preserving voltage stability across panels and distributed subcircuits.
Key specifications include a 112.5 kVA volt-ampere rating, 480 V primary, 208Y/120 V secondary, 60 Hz frequency, and taps set at two positions of +2.5% and two positions of -2.5%. The 80 °C rise rating supports high-temperature environments, while aluminum windings and a robust frame (917) contribute to durability.
It is well-suited for both. The unit delivers stable three-phase power with precise voltage regulation thanks to the taps, and its low audible noise (47 dB) minimizes acoustic impact in crowded data center or plant spaces. The NEMA TP-1 efficiency and UL listing add regulatory confidence for critical loads and continuous operations.
The N48D28B12EELS47 carries UL Listed certification and complies with NEMA TP-1 efficiency standards, supporting regulatory and energy-efficiency requirements. These certifications help simplify procurement, vendor qualification, and energy-audit processes, while the low-noise and shielding features support EMI/EMC considerations in networked plant environments.
The transformer carries a one-year warranty from installation (or 18 months from shipment). Plan for routine inspections of connections, cooling, and protective enclosures, with attention to the WS34 weather shield and electrostatic shielding status for EMI integrity. The robust aluminum windings and durable frame reduce maintenance cycles and extend service intervals, supporting predictable lifecycle costs.
