FAQs
Installation should respect the NEMA 3R enclosure rating for indoor-outdoor use and ensure proper clearance for cooling. Use the 3Z wiring connection as specified, confirm primary and secondary voltages match system requirements (240/480 V to 115/230 V), and verify UL Listed certification is documented during commissioning to support compliance and traceability.
The transformer is single-phase, 60 Hz, with a 2 kVA rating. Primary voltages available are 240 V and 480 V, while secondary voltages are 115/230 V. It uses aluminum coil material, has a 68 frame, and is designed for indoor-outdoor use with a 13.41 in height, 6.37 in width, and 6.52 in depth.
Yes. The S20N13S02 uses an NEMA 3R enclosure and is rated for indoor-outdoor service, providing weather resistance and rugged performance in outdoor switchgear, warehouse yards, and exposed production areas. This makes it a reliable choice for facilities requiring durable, space-efficient power conversion near equipment exposed to the elements.
Eaton provides a warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. In addition, the UL Listed certification supports ongoing compliance and quality assurance, while Eaton’s support network helps with installation guidance and troubleshooting within typical distribution and control system projects.
Its compact, encapsulated design fits tight control panels and reduces wiring complexity by delivering ready-to-wire secondary voltage in a single unit. The rugged NEMA 3R enclosure enables reliable outdoor use, lowering equipment exposure risks. Reliable voltage isolation and consistent 2 kVA capacity help minimize power interruptions in equipment racks and production lines.
