FAQs
Installation should follow the 3-phase 480 V wiring scheme with proper grounding and enclosure clearance. Utilize the 480-208Y/120 secondary configuration as specified to ensure correct voltage transformation. Verify UL Listed clearance, proper venting for the cabinet, and adherence to DOE2016 Efficient requirements. Use Eaton’s specification sheet for terminal layout, torque specs, and accessory recommendations to minimize commissioning time.
The N48D28F7521 employs a K-Factor nonlinear design intended to mitigate harmonic currents and reduce transformer overheating under non-sinusoidal loads. This improves power quality, lowers thermal stress, and extends insulation life. In practice, you’ll see steadier secondary voltages and better overall efficiency in systems with heavy drive loads, rectifiers, or nonlinear power electronics.
Yes. With a 75 kVA rating and a 3-phase 480 V primary, it aligns with common data center and manufacturing power architectures. Its nonlinear K-Factor design helps manage harmonic currents from IT equipment and drives, while DOE2016 Efficient and UL Listed certifications support regulatory compliance, energy incentives, and safety in mission-critical spaces.
The unit is UL Listed and meets DOE2016 Efficient standards. UL Listing provides safety validation for electrical components and assemblies, helping with compliance during audits and in facility approvals. DOE2016 Efficient status indicates verified energy performance, supporting utility incentives and ongoing energy-management commitments within industrial operations.
ROI is driven by energy savings from DOE2016 efficiency, reduced heat management costs due to better harmonic handling, and increased equipment uptime from stable power.
