Eaton N39M28T15XAFCULS42 K-Factor Transformer - UL Listed
Part Number: N39M28T15XAFCULS42
Quick Summary
Eaton K-Factor nonlinear ventilated transformer provides reliable three-phase power for industrial panels and equipment. A common challenge in uneven loading is heat buildup and acoustic noise that shorten uptime and raise maintenance costs. This unit carries UL Listed certification and follows NEMA TP-1 efficiency guidelines, with fungus-proof construction for harsher environments. Its rugged 15 kVA rating and copper windings deliver predictable performance, while the 400 V primary and 208Y/120 V secondary support standard power distribution architectures. Designed for straightforward installation and compatibility with Eaton's Transformer Flex Center ecosystem, it offers scalable protection and long-term value for electrical distribution upgrades.

FAQs
When upgrading existing panels, verify the 912B frame fits within the enclosure footprint and ensure adequate clearance for 308 lb weight. Use the +2.5% and -2.5% tap settings to balance supply voltage on site. Confirm 50-60 Hz supply and 400 V input with a 208Y/120 V secondary, and maintain UL-listed clearance per electrical code.
The K-Factor nonlinear design (K-13) is engineered to accommodate harmonic currents, reducing peak temperatures and insulating stress. This improves reliability in drives and non-linear loads, supporting longer insulation life and lower maintenance costs in harsh manufacturing environments.
Yes. The N39M28T15XAFCULS42 is a three-phase transformer with a 400 V primary and 208Y/120 V secondary intended for Eaton and compatible distribution schemes. It includes taps for voltage adjustment and is UL Listed, aligning with common industrial panel standards and installation practices.
The transformer is rated for low sound operation at 42 dB, which supports use in control rooms and adjacent spaces. For near-assembly-line environments, confirm installation away from high-sensitivity equipment and consider enclosure acoustics if needed.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever comes first (Policy 25-000). For ROI planning, factor in long-term reliability, reduced downtime, and compliance with UL Listed and NEMA TP-1 efficiency in total cost of ownership.
