Eaton S20N11S83N Encapsulated transformer - UL Listed
Part Number: S20N11S83N
Quick Summary
Eaton S20N11S83N encapsulated transformer powers control panels with reliable, compact, single‑phase performance. Many automation projects struggle to fit a power transformer into tight enclosures while meeting harsh indoor-outdoor conditions. UL Listed certification and a NEMA 3R enclosure rating provide essential safety and weather resistance for control rooms, factories, and outdoor equipment housings. With a 0.15 kVA rating and aluminum coil construction, this unit offers lightweight installation, reduced panel space, and efficient heat management. The combination of robust enclosure protection, standard voltages, and Eaton's warranty translates into faster commissioning, lower total cost of ownership, and improved reliability across machine builds and process lines.

FAQs
For optimal results, plan for a compact 4.5 inch by 6 inch by 6 inch footprint with a total weight of about 10 lb. Use the 3A wiring connection, ensure adequate clearance for heat dissipation, and mount within a NEMA 3R rated enclosure to maintain UL compliance and weather resistance in indoor-outdoor environments.
The S20N11S83N is a single‑phase transformer with 240 V and 480 V primary inputs and a 120/240 V secondary. It operates at 60 Hz and is rated at 0.15 kVA, suitable for control circuits and modest power distribution within automation panels.
Yes. It uses a NEMA 3R enclosure and Weathershield for indoor-outdoor service, offering weather resistance and protection against dust and moisture, making it appropriate for outdoor panels and exposed installations while maintaining UL Listed compliance.
The unit is UL Listed and designed with a NEMA 3R enclosure to support indoor-outdoor use. Its rugged EP design and aluminum coil further contribute to reliability in industrial settings, simplifying regulatory alignment and supplier qualification for safety and performance.
The 0.15 kVA rating matches typical control circuits, reducing wasted capacity and heat. Aluminum windings lower weight and handling costs, while UL listing and a robust enclosure minimize field failures. Combined, these factors translate to lower maintenance costs, faster commissioning, and a lower total cost of ownership over the system’s life.
