Eaton N48M28F1221CUSR K-Factor transformer - UL Listed
Part Number: N48M28F1221CUSR
Quick Summary
Eaton N48M28F1221CUSR is a K-Factor nonlinear ventilated transformer for industrial power distribution. These devices address efficiency and reliability challenges in live power systems, reducing heat and energy waste that can impact uptime. DOE2016 Efficient and UL Listed certifications help meet strict compliance while simplifying procurement. Designed for three-phase power with a 480 V input and 208Y/120 V output, it supports scalable industrial installations and lowers total cost of ownership. In practice, teams value detailed specifications—112.50 kVA rating, 1200 lb weight, and 115 °C rise—when planning cooling, space, and service intervals. This approach aligns with power management and electrical distribution priorities across data centers and manufacturing facilities.

Feature → Business Impact → Application: The K-Factor nonlinear ventilated design reduces transformer heat generation by directing heat away from windings and circuitry, which lowers cooling demand and improves overall system efficiency. That translates into measurable energy savings during peak loads and quieter, more stable operation in critical paths. For data centers and manufacturing cells, this means higher availability without oversized cooling investments, enabling tighter racks and more compact electrical rooms. DOE2016 Efficient and UL Listed compliance provide predictable procurement and risk reduction. The efficiency gains cut line losses across the load profile, contributing to lower utility bills and longer service intervals due to gentler thermal cycling. The rugged 943 frame and ventilated housing simplify mounting and service access in retrofit projects and new builds alike. Three-phase 480 V input with 208Y/120 V secondary matches common panel configurations, minimizing adapters and field modification. The 112.50 kVA rating preserves headroom for future load growth while maintaining a compact footprint that fits into standard electrical rooms. Quick compatibility reduces project schedule risk and accelerates commissioning. Physical attributes support installation in constrained spaces: 31.5 in L, 34.5 in W, 51 in H, and a weight of about 1200 lb. The 283B wiring connection and UL-listed construction streamline panel integration and compliance with electrical codes. Service access is straightforward, aided by Eaton's datasheets and the K13 feature set for reliable operation. Reliability comes from deliberate thermal design and robust construction that withstands demanding environments with a 115 °C rise. The energyefficient ventilated architecture reduces hotspots and supports longer insulation life, while DOE2016 and UL listings reinforce ongoing regulatory alignment. For owners and operators, this translates to lower maintenance costs and improved asset performance over the transformer’s lifecycle.

FAQs
The transformer occupies a footprint of 31.5 in L x 34.5 in W with a height of 51 in and weighs about 1200 lb. Plan for ventilation clearance and service access around the rugged frame (frame 943) and accommodate the wiring connection (283B) for panel integration. Refer to Eaton’s specification sheet for exact clearance recommendations in your site.
K-Factor nonlinear design reduces heat buildup by improving heat dispersion, which lowers cooling requirements and improves overall efficiency. In a 112.5 kVA, three-phase system, this translates to lower load losses and more stable temperatures during peak loading, contributing to longer insulation life and reduced maintenance needs in industrial environments.
Yes. The N48M28F1221CUSR is specified for a 480 V primary and a 208Y/120 V secondary in a three-phase configuration, aligning with common industrial panels and minimizing the need for additional adapters or field alterations.
This transformer is UL Listed and DOE2016 Efficient compliant. These certifications support compliance with electrical safety standards and energy performance requirements, facilitating procurement and regulatory alignment across industrial facilities.
ROI is driven by DOE2016 efficiency and reduced heat loss, which lowers operating energy, cooling load, and potentially maintenance cycles due to gentler thermal cycling. While exact payback depends on site load profiles, facilities with high stable loads and tight electrical rooms typically realize meaningful total cost of ownership benefits over the asset lifecycle.
