Eaton S29N27S26 Encapsulated Transformer - UL Listed
Part Number: S29N27S26
Quick Summary
The Eaton general-purpose encapsulated transformer powers control panels and automated equipment by converting 208 V to 277 V at 60 Hz. In tight spaces, engineers confront layout constraints, weather exposure, and wiring complexity that slow installation and increase risk. UL Listed safety certification, a NEMA 3R enclosure for indoor-outdoor use, and a 115 °C rise rating help ensure reliable operation in harsh plants. Its compact 0.25 kVA rating and aluminum windings support efficient, cost-effective power conversion for industrial controls, while simple wiring and Eaton’s warranty enhance total cost of ownership.
