The S48G11S15CU delivers a 15 kVA rating with a 480 V primary and 120/240 V secondary, enabling clean, stable power for control panels and automation cabinets, while reducing voltage drop and design complexity. Copper windings provide lower resistance losses and improved thermal performance, translating to greater efficiency and longer service life in high-demand applications such as machinery drives and process equipment. The EP encapsulated design and indoor-outdoor enclosure offer rugged insulation and moisture resistance, enabling installation in variable environments and reducing protective enclosures costs for outdoor or damp locations. A -5% FCBN tap size enhances voltage regulation under fluctuating input conditions, helping maintain equipment performance and protecting sensitive electronics. Wiring convenience is supported by a 2D connection scheme, allowing flexible terminations and faster panel wiring. At 240 lb and with dimensions of 13.38 in by 19 in by 10.52 in, it fits common industrial footprints while supporting straightforward mounting and service access. The Eaton warranty provides risk reduction on procurement, while the manufacturer certification status ensures alignment with evolving regulatory requirements in power distribution for automation projects.

FAQs
For control panel applications, position the transformer to minimize conduit runs and allow adequate clearance for heat dissipation. Use the 2D wiring configuration to simplify terminations and ensure accessible clearance around the 13.38 in width and 19 in height. Mount within the available 180 frame footprint and plan for a 240 lb weight, factoring in vibration and service access. Ensure the -5% FCBN tap is set for nominal input conditions to maintain voltage at the 120/240 V secondary.
The unit is a single-phase transformer rated for 60 Hz with a 480 V primary and a 120/240 V secondary, delivering 15 kVA. It uses copper windings and features a 2 at -5% FCBN tap, supporting stable voltage conversion even with input fluctuations. The enclosure is designed for indoor-outdoor use, enabling flexible installation in various industrial settings.
Yes. The S48G11S15CU is specified as an indoor-outdoor transformer with an encapsulated EP design, offering robust protection against moisture and dust. This makes it well-suited for outdoor equipment enclosures, loading docks, or damp factory floors, while still delivering reliable performance in protected indoor panels. Always verify mounting and ambient ratings for your exact installation site.
Certifications for this transformer are provided by the manufacturer and can vary by configuration. Common certifications requested in industrial projects include CE, SIL, and IP ratings, but you should confirm the exact approvals with Eaton for your chosen configuration. Review the Eaton specification sheet and the transformer catalog for the precise compliance details before procurement.
With 15 kVA, copper windings, and a robust indoor-outdoor enclosure, the unit offers low loss operation and durable performance, reducing energy waste and unplanned downtime. The EP encapsulation protects against environmental exposure, lowering protection costs and extending service life. The warranty (one year from installation or 18 months from shipment) reduces procurement risk, while the 480 V to 120/240 V conversion supports standardized panel design and faster commissioning in automation projects.
