FAQs
Plan for a level, vibration-free mounting surface with adequate clearance for airflow around the vented housing. The unit weighs 430 lb and measures roughly 21.13 in by 24.88 in by 36.88 in, so ensure floor loading and pallet handling capabilities. Provide accessible wiring space for 480-208Y/120 V connections and compliance with UL-listed mounting requirements.
K-Factor nonlinear design accounts for harmonic currents from nonlinear loads, reducing transformer heat and voltage distortion. The N48D28F4521CU uses a K13 designation to manage harmonics and maintain service life for downstream drives and controls. This improves equipment reliability and helps avoid oversizing due to harmonic limits.
Yes, it is suitable for many mid-size facilities. With a 45 kVA rating and a three-phase 480-208Y/120 V output, it supports data center power rails and motor drives on factory floors. Its vented enclosure aids cooling in dense load scenarios. Always verify load profiles and phase balance to ensure proper kVA demand and voltage compatibility with upstream gear.
The N48D28F4521CU is UL Listed, which confirms compliance with recognized safety standards and simplifies procurement and audits. This certification reduces risk in industrial environments. For broader regulatory requirements, consult Eaton datasheets and local codes to determine if additional certifications are needed for your project.
The vented, robust construction supports cooler operation and longer service intervals, reducing maintenance downtime. The K-Factor design helps maintain power quality under nonlinear loads, lowering fault-driven downtime. Over time, safety certification and reliable performance translate to lower maintenance costs and improved uptime for critical manufacturing or data-center workloads.
