Encapsulated transformer
Feature → Business Impact → Application: The 5 kVA encapsulated transformer delivers strong power capacity within a compact footprint, enabling efficient space planning in control panels and small switchgear assemblies. This directly reduces enclosure size requirements and lowers installation costs, while maintaining robust thermal margins for continuous operation in demanding environments. Feature → Business Impact → Application: Single-phase operation simplifies wiring, installation, and fault isolation, reducing commissioning time and improving system uptime in machine controls and automation panels. This is ideal for retrofits or new builds where quick deployment and reliable power conversion are critical. Feature → Business Impact → Application: NEMA 4X enclosure resilience provides excellent protection against dust, moisture, and varying temperatures, lowering field maintenance needs and extending service intervals in industrial settings. This suits outdoor or harsh indoor installations common in process lines and packaging equipment. Feature → Business Impact → Application: General purpose design supports versatile secondary voltages (120/240 V) from a 240/480 V primary, enabling seamless integration with downstream controls, relays, and drive systems in low voltage distribution. This reduces the need for multiple transformers and minimizes total cost of ownership. Feature → Business Impact → Application: Encapsulation enhances mechanical robustness and moisture sealing, improving reliability in environments with vibration or humidity, such as CNC machines, conveyors, and robotic cells. This translates to lower mean time between failures and predictable performance. Feature → Business Impact → Application: The manufacturer's encapsulation approach eases installation and serviceability, allowing straightforward mounting, safer wiring practices, and easier future upgrades for evolving control architectures.

FAQs
Plan for a dedicated enclosure space with adequate ventilation and clearance for wiring. Mount the unit on a stable surface or rack, ensuring compliance with weight support and handling procedures. Verify ambient temperature limits and enclosure protection (NEMA 4X suitability) to maintain performance and safety in harsh environments.
Yes. The 5 kVA single‑phase transformer supports 240/480 V primary to 120/240 V secondary, making it ideal for control panels, drives, and automation cabinets. Its encapsulated design reduces space, improves protection, and simplifies wiring, which accelerates panel assembly and commissioning.
Certifications are identified by the manufacturer and can vary by region. The unit is offered with a NEMA 4X enclosure for rugged protection, and regional safety certifications (for example CE/UL) should be confirmed with Eaton during purchasing or via the product spec sheet.
Encapsulation enhances enclosure integrity and moisture resistance, reducing moisture ingress risk and corrosion. This translates to lower maintenance frequency, longer mean time between failures, and more predictable performance in environments with dust, humidity, or vibration.
By combining a compact footprint with high reliability and simplified installation, the S20N11E05CUSS4X lowers upfront wiring and enclosure costs, reduces panel size, and minimizes downtime. Over the system lifecycle, this yields lower total cost of ownership and faster time-to-value for automation upgrades.
