Eaton Specification Sheet - N48D31B49CU
Feature → Business Impact → Application: The K-Factor nonlinear design mitigates harmonic currents, reducing overheating risk and extending equipment life in facilities with mixed loads, such as data centers and manufacturing lines. This supports more stable operation and lower maintenance costs in critical power paths. Feature → Business Impact → Application: With a 150 kVA three‑phase rating and 480-220Y/127 V output, it integrates smoothly into standard plant electrical infrastructure, streamlining panel design and reducing voltage mismatch concerns in control rooms and MCCs. Feature → Business Impact → Application: Copper windings with an 80C rise offer higher thermal tolerance, improving reliability under peak loading and during thermal excursions in hot environments. Feature → Business Impact → Application: Ventilated construction provides enhanced cooling, enabling longer duty cycles, fewer thermal trips, and better performance in dense installations like machine shops and process lines. Feature → Business Impact → Application: Comprehensive documentation and Eaton catalogs simplify procurement and installation, while the option to verify certifications with the manufacturer helps ensure regulatory compliance in regulated facilities. The combination of these attributes supports improved efficiency, predictable maintenance, and faster engineering approvals in power distribution projects.

FAQs
When installing the N48D31B49CU, ensure proper three-phase connections (480 V primary to 480-220Y/127 V secondary), and provide adequate ventilation and clearance around the unit. Follow Eaton guidance from the transformer catalog and datasheet, use appropriate wiring for copper windings, and verify mounting provisions in your electrical room to prevent overheating and ensure safe service access.
The K-Factor nonlinear design is engineered to accommodate distorted loads by shaping impedance and thermal response, reducing hotspot formation and improving temperature rise profiles. This leads to more stable output under harmonics, decreased maintenance cycles, and improved reliability in facilities with variable or non-sinusoidal loads, such as motor drives and rectifier systems.
Yes. With a 150 kVA, three-phase configuration and a 480-220Y/127 V output, the transformer is well-suited for mid-range data center power distribution schemes. Its ventilated design and copper windings help manage thermal stress from non-linear server loads, while the K13 XFMR specification supports improved harmonic handling in critical IT environments.
Certification status for this model is listed as Contact Manufacturer. For regulatory compliance, consult Eaton’s specification sheet and catalog references, and request region-specific approvals (for example CE or SIL) from Eaton or your authorized distributor to meet local codes and safety requirements.
The combination of K-Factor design, copper windings, and 80C rise enables more reliable performance under harmonic load and higher ambient temperatures, reducing thermal-related outages. This translates to lower maintenance downtime, improved power quality, and a favorable return on investment in facilities with dense electrical loading and stringent uptime requirements.
