Eaton Specification Sheet - N48M47F4516CU
DOE 2016 efficiency combined with an 115 °C rise specification reduces core and copper losses, delivering lower operating temperatures and improved life expectancy. For engineers, this means lower energy waste and more predictable performance under peak loads in automated production lines. Voltage flexibility with a 480 V primary and 480Y/277 V secondary, 3-phase at 60 Hz, 45 kVA rating simplifies panel design, reduces interconnects, and speeds deployment on machines and distribution pads. The durable construction uses copper windings and a shielded design to improve efficiency and fault tolerance within a NEMA 2 enclosure, enabling reliable operation in indoor environments and reducing maintenance costs over time. Tap changer and connections provide 2 at +2.5%, 4 at -2.5% taps with a 283B wiring connection, allowing on-site voltage optimization for load banks or motor starts and reducing upfront hardware needs. Regulatory compliance and footprint considerations are supported by UL Listed, DOE 2016 efficiency, and 67 CFR Part 431 notes, while a compact footprint with floor-or-wall mounting simplifies installation in control rooms and switchgear areas, balancing space with performance for automation projects.

FAQs
This unit is designed for floor or wall mounting with a NEMA 2 enclosure, so plan for indoor installation in controlled environments. Dimensions are 24 in deep, 30.5 in wide, and 43 in high, with a weight of 672 lb, which informs ramp, hoist, and anchoring requirements. Use the 283B wiring connection and 2 at +2.5%, 4 at -2.5% taps to optimize voltage delivery on-site without extra external equipment.
DOE 2016 efficiency reduces no-load and load losses, lowering ongoing energy consumption and heat generation. This translates to lower utility bills, cooler operating temperatures, and extended insulation and component life. In high-duty environments with constant power transfer, the savings compound over time, improving total cost of ownership and return on investment for automation and manufacturing applications.
Yes. The transformer is rated 45 kVA with a 480 V primary and a 480Y/277 V secondary, designed for 60 Hz systems. Its 3-phase configuration supports distribution to control panels, drives, and motors, reducing the need for multiple step-down units. The copper windings and shielded construction help maintain voltage stability under varying load conditions.
The N48M47F4516CU carries UL Listed certification and DOE 2016 efficiency compliance. Catalog notes reference 67 CFR Part 431 (2016) Efficient standards. These certifications help meet regulatory requirements for energy efficiency, safety, and documentation in industrial facilities, aiding in audits and supplier qualification processes.
The combination of high efficiency, robust copper windings, and a shielded design reduces losses and fault probability, lowering maintenance costs and unscheduled downtime. With a stable 45 kVA rating and straightforward installation (floor or wall mounting), the unit delivers predictable performance, streamlined inventory, and improved life-cycle value for automation and manufacturing operations.
