Encapsulated construction with an aluminum coil minimizes moisture ingress and reduces vibration, delivering higher reliability in tight panel spaces. The robust design lowers maintenance frequency and extends service life for control cabinets in manufacturing lines and packaging equipment. This approach also simplifies installation where space is at a premium and airflow is restricted. Voltage compatibility and ratings provide flexibility across diverse sites. With 240/480 V primary and 120/240 V secondary, a 1 kVA rating, and 50-60 Hz operation, the unit supports multiple power needs from a single part, streamlining inventory and reducing spare-part costs for OEMs and integrators. It is well-suited for machine tools, conveyors, and process equipment that demand reliable step-down or isolation between subsystems. Rugged enclosure and weather resistance enable indoor-outdoor deployment. The NEMA 3R enclosure paired with indoor-outdoor capability helps protect against dust, moisture, and temperature swings in production stalls, guard shacks, or outdoor control panels, lowering field failure rates. UL Listed certification ensures compliance with safety standards and quality control, while Eaton's warranty policy provides financial protection during the first year of operation. The combination of certifications and a 1 kVA rating gives buyers confidence to standardize on a single product for mixed-voltage applications, reducing procurement complexity. Additional features such as electrostatically shielded construction improve shielding performance and reduce EMI in sensitive automation circuits, while the 50/60 Hz catalog notes confirm wide regional compatibility. Overall, the S20N11E01X delivers predictable performance, helping technicians achieve uptime targets and project ROI.

FAQs
The unit uses a NEMA 3R enclosure suitable for indoor-outdoor use, enabling outdoor or semi-enclosed installations. With a 1 kVA rating and a single-phase configuration, plan for appropriate panel space, ventilation, and wiring routes to accommodate 240/480 V primary and 120/240 V secondary connections. Verify mounting clearances and protect the transformer from physical impact in harsh environments.
Primary voltage is 240 V or 480 V, secondary voltage is 120/240 V, with a 1 kVA power rating and a 50–60 Hz frequency rating. The aluminum coil supports efficient conductivity, and the 115 °C rise indicates usable thermal headroom under normal load. This configuration supports isolation and voltage conversion for mixed-voltage automation panels.
Yes. The S20N11E01X uses a NEMA 3R enclosure and is rated for indoor-outdoor service, providing protection against dust, moisture, and temperature variations. The UL Listed certification adds safety assurance, making it appropriate for outdoor control stations, remote sensors, and industrial machinery common in manufacturing environments.
The transformer is UL Listed and features a NEMA 3R enclosure for rugged, compliant operation in varied environments. Catalog notes confirm 50/60 Hz compatibility, and the enclosure and build quality support regulatory compliance for industrial electrical installations. This reduces audit findings and accelerates project approvals.
The product is covered under Eaton's warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. This warranty helps mitigate maintenance costs and downtime. Combined with a robust enclosure and long service life, the S20N11E01X contributes to a lower TCO for OEMs and end users.
