Eaton Specification Sheet - N48M47F15A
Feature → Business Impact → Application: The K-13 design creates a nonlinear, ventilated transformer that better withstands nonlinear loading, reducing overheating risk and enabling higher overall system reliability in demanding environments such as motor drives and CNC controls. This translates to fewer unplanned outages and lower cooling costs in manufacturing or processing facilities where harmonic currents are common. Feature → Business Impact → Application: Aluminum windings and an electrostatic shield deliver improved electrical performance and reduced stray capacitance, enhancing protection for sensitive controls and improving EMI/RFI management in automated lines. Feature → Business Impact → Application: The 480 V primary and 480Y/277 V secondary support common utility and facility distributions, offering seamless integration with modern switchgear and panelboards in data centers and industrial plants. Feature → Business Impact → Application: Taps at +2.5% FCAN and −2.5% FCBN provide feeder flexibility to accommodate voltage drift without compromising protection or regulation, simplifying commissioning across multiple sites. Feature → Business Impact → Application: The WS38 weathershield and ventilated frame 912B design improve thermal performance and environmental resilience, enabling outdoor or semi‑indoor installation in harsh or high‑ambient‑temperature conditions. Feature → Business Impact → Application: A 15 kVA three‑phase footprint aligns with critical load centers such as VFDs, PLC racks, and small motor packages, delivering efficient energy management while enabling scalable expansion. This combination addresses common objections about installation cost, maintenance complexity, and compatibility with existing Eaton catalogs and spare parts, ensuring a smoother procurement cycle and faster time-to-value for engineering teams.

FAQs
When installing the N48M47F15A, ensure a properly sized enclosure for the 912B frame, adequate ventilation for thermal management, and correct wiring to the 480 V primary and 480Y/277 V secondary. Verify available taps (+2.5% FCAN and -2.5% FCBN) are selected for the current voltage conditions, and confirm compliance with local electrical codes and UL Listed safety requirements before commissioning.
The K-Factor nonlinear design handles harmonic loading more effectively, reducing overheating risk and improving voltage regulation under nonlinear loads. This leads to higher overall efficiency, lower cooling demand, and enhanced protection for downstream equipment such as drives and PLCs, which translates to longer equipment life and reduced maintenance intervals.
Yes. With a 480 V primary and a 480Y/277 V secondary, three-phase operation, and a 15 kVA rating, the N48M47F15A is well-matched for data center distribution panels and industrial control cabinets. Its aluminum windings, shield, and ventilated design support tighter temperature control and EMI considerations in challenging environments.
This model is UL Listed, providing recognized safety certification for electrical devices. While UL Listed supports safe integration, verify additional regulatory requirements for your region or application (such as CE or IP if applicable to your facility) and ensure compatibility with your project specifications and safety policies.
Expect reduced maintenance due to improved thermal performance and lower overheating risk, resulting in fewer unscheduled outages. The ventilated design and shielded windings help maintain voltage stability under varying loads, contributing to longer asset life and more predictable energy usage, which supports a stronger return on investment over the equipment lifecycle.
