Eaton N48M47T15A Transformer - UL Listed K-13
Part Number: N48M47T15A
Quick Summary
The Eaton N48M47T15A transformer delivers K-Factor nonlinear performance for three-phase power distribution. Facilities teams often wrestle with harmonic currents, voltage swings, and heat buildup that shorten equipment life and disrupt uptime. This UL Listed device leverages a K-13 design with electrostatic shielding to help curb EMI and improve reliability, while its ventilated construction aids cooling in dense switchgear and cabinet installations. With a 15 kVA rating, 480 V primary and 480Y/277 V secondary, plus selectable taps, it supports flexible power distribution across manufacturing lines, data centers, and process facilities. The result is better voltage regulation, reduced maintenance needs, and a lower total cost of ownership for critical loads.

FAQs
Plan for a sturdy mounting surface that supports the 231 lb weight. The 16.5 in depth, 23 in width, and 30 in height define a footprint suitable for dedicated transformer spaces or protected outdoor enclosures with WS38. Ensure adequate clearance for cooling and access to taps and connections, and follow wiring diagrams in the Eaton datasheet for proper 480 V to 480Y/277 V connections.
Key specs include a 15 kVA rating, 60 Hz frequency, three-phase configuration, 480 V primary, 480Y/277 V secondary, and taps at 2 with +2.5% and 4 with -2.5% for voltage regulation. The design uses aluminum windings, an electrostatic shield, and a 150 °C rise, enabling stable operation under load swings and harmonic conditions.
Yes. The N48M47T15A’s K-13 nonlinear performance and EM shielding help mitigate harmonics and overheating in environments with dense loads. The 480Y/277 V secondary is common for facility distribution, and the unit’s UL Listed status supports compliance in regulated spaces, making it well-suited for data centers, manufacturing lines, and process facilities.
This transformer is UL Listed, confirming electrical safety compliance in North America. For regional applicability, always verify local codes and any project-specific certification requirements with the Eaton datasheet and your commissioning team.
Eaton provides a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first.
