Eaton N48M28F4521CSCU K-Factor Transformer - K13
Part Number: N48M28F4521CSCU
Quick Summary
The Eaton N48M28F4521CSCU K-Factor nonlinear transformer is a three-phase power conditioning device designed to support non-linear loads in industrial facilities. Operators often struggle with harmonic distortion, overheating, and outages when vented transformer designs are undersized or ill-suited for modern automation systems. This unit carries UL Listed safety certification, reinforcing reliability and compliance for industrial environments, while its K13 K-Factor specification signals robust handling of harmonic content from drives and other non-linear loads. In practice, this transformer delivers measurable business value through improved reliability, reduced maintenance, and predictable performance within mid-size power distributions. Its 45 kVA rating, three-phase configuration, and compact yet robust build support integration into equipment racks, panelboards, and machine rooms.

FAQs
Plan for a three-phase 480-208Y/120 supply with N48M28F4521CSCU mounted in a ventilated enclosure. Note its 21.13 in length, 36.88 in height, 24.88 in width, and 430 lb weight for clearance, mounting, and lifting. Ensure adequate cooling and accessibility for maintenance, with UL Listed compliance supported by proper wiring methods and panel ratings.
K13 indicates a higher tolerance to harmonic currents produced by devices like VFDs and switching supplies. This reduces overheating and insulation stress, improving transformer life and reliability. For engineers, the benefit translates into lower maintenance costs, fewer outages, and more predictable voltage regulation under heavy non-linear loading in automation environments.
Yes. The N48M28F4521CSCU is designed for non-linear loads common in motor drives and automation panels. Its 45 kVA rating, three-phase configuration, vented cooling, and UL Listed safety certification make it appropriate for critical power conditioning in manufacturing lines and equipment enclosures, helping to maintain stable voltage and reduce harmonic-related issues.
UL Listed indicates the transformer has been tested for electrical safety and performance according to recognized standards. For procurement and regulatory audits, this certification supports safe operation, traceability, and qualification through established safety programs, reducing compliance risk in industrial installations and distributed power systems.
The transformer’s dimensions, weight, and standard footprint simplify retrofit and new-install planning, reducing site-time and integration risk. Because it’s a standard, globally sourced part, spare parts availability improves maintenance efficiency, downtime is minimized during replacements, and total cost of ownership is lowered through predictable performance and lifecycle reliability.
