Feature → Business Impact → Application: Encapsulated copper-wound design provides excellent protection against moisture and dust, reducing insulation degradation and extending transformer life. This translates to lower maintenance costs and fewer field failures, especially in outdoor or damp environments where reliability matters for critical loads in manufacturing lines and processing plants. Feature → 10 kVA single‑phase rating with 240/480 V primary and 120/240 V secondary enables flexible equipment sizing and rapid deployment in existing panels, minimizing panel real estate and simplifying retrofits across industrial automation and distribution installations. Feature → NEMA 3R enclosure and Grade 304 stainless steel construction offer rugged durability and corrosion resistance, enabling outdoor service in warehouses, loading docks, and outdoor sub-panels with confidence in harsh weather. Feature → Copper windings with a 115 °C rise specification support efficient heat dissipation under continuous operation, improving overall performance and reducing temperature-related derating in high-load scenarios. Feature → 3A wiring connection, 60 Hz single‑phase operation, and a compact 179 frame streamline installation and service, lowering installation time and facilitating easy integration into new or existing control cabinets. With UL Listed certification and robust mechanical design, this transformer delivers dependable performance, predictable maintenance, and a lower total cost of ownership for industrial power distribution.

FAQs
Install the S20N11S10CUSS in a suitable enclosure rated for indoor-outdoor service, with proper clearance for ventilation. Mount the unit on a rigid support compatible with a 179 frame, connect the 3A wiring configuration, and apply 240/480 V primary power to the input while routing the 120/240 V secondary conductors to the load. Follow any local electrical codes and Eaton’s installation guidelines to ensure UL compliance and safe operation.
The transformer operates on 60 Hz single-phase power, with a primary voltage of 240 V and 480 V and a secondary voltage of 120/240 V. This configuration enables straightforward distribution to compatible equipment and control circuits, reducing the need for multiple transformers in a panel and simplifying spare parts logistics for maintenance teams.
Yes. The unit features a Grade 304 stainless steel enclosure and a NEMA 3R rating, designed for indoor-outdoor use. These features protect windings and components from moisture, dust, and corrosion, supporting reliable operation in loading docks, outdoor panels, and wet-industrial applications while minimizing maintenance requirements.
The transformer is UL Listed, confirming compliance with recognized safety standards for electrical equipment. In addition, its enclosure and construction meet rugged industrial requirements (NEMA 3R), enabling safe operation in environments where weather resistance and enclosure integrity are critical to performance and compliance.
The encapsulated copper-windings design, stainless-steel enclosure, and UL Listed certification contribute to reduced field maintenance and longer service intervals. This translates to lower downtime and operating costs, improved reliability for control panels and distribution circuits, and a favorable total cost of ownership in facilities aiming for durable, compliant power distribution solutions.
