Eaton S48N29S15 General-Purpose Transformer - UL Listed
Part Number: S48N29S15
Quick Summary
Eaton S48N29S15 general-purpose encapsulated transformer converts 480 V to 208 V for industrial control panels. This compact unit helps reduce panel footprint while delivering reliable power where space is at a premium. Many projects struggle with outside exposure, moisture, and dust in control rooms; the NEMA 3R enclosure and indoor-outdoor capability address those challenges. The UL Listed certification supports safety and compliance for demanding environments, while the aluminum winding provides corrosion resistance in harsh settings. For system designers, the combination of 60 Hz operation, 15 kVA capacity, and a rugged enclosure translates into lower maintenance costs and higher uptime in power management and distribution applications.

FAQs
The S48N29S15 uses the 536B wiring connection and is rated for 480 V primary to 208 V secondary at 60 Hz. For best results, follow Eaton’s installation guidelines, mount the unit in its NEMA 3R enclosure, and route conductors per local codes. Ensure the transformer is adequately mounted to manage heat rise and ambient conditions, then verify voltage output at the panel terminals before connecting downstream loads.
Key ratings include 15 kVA apparent power, single-phase configuration, primary voltage 480 V, secondary voltage 208 V, frequency 60 Hz, and a 115 °C rise. The enclosure is rated NEMA 3R with indoor-outdoor suitability and the windings are Aluminum, contributing to reliable thermal performance and corrosion resistance in demanding environments.
Yes. The S48N29S15 features an NEMA 3R enclosure and Weathershield suitability for indoor-outdoor service, making it well-suited for outdoor control panels and exposed installations. Its 15 kVA rating supports mid-range automation loads, while the aluminum winding and 60 Hz operation ensure stable performance in typical manufacturing environments.
UL Listed indicates conformity to recognized safety standards for electrical products, supporting safer operation and easier regulatory compliance in industrial facilities. It also helps streamline procurement and reduces the risk of non-compliance during audits. Regular maintenance should still follow Eaton’s guidelines and local electrical codes to maintain the listing’s validity.
With aluminum windings and a rugged NEMA 3R enclosure, the transformer offers durable performance with lower corrosion risk and reduced maintenance compared to non-encapsulated units. The 15 kVA rating suits numerous loads, and the one-year warranty provides initial protection. The combination of reliability, reduced downtime, and long service life drives total cost of ownership down in power management and distribution deployments.
