Encapsulated transformer
Encapsulated construction delivers robust protection against moisture and dust, reducing field failures and extending service life in outdoor or harsh indoor environments. Business impact: lower maintenance costs, higher uptime, and safer enclosure integration. Application: control panels in manufacturing lines, outdoor substations, and compact machine enclosures. The 5 kVA single-phase rating matches typical control power and auxiliary circuits, enabling reliable operation of relays, sensors, and drives while minimizing energy waste. Implementation with copper windings improves thermal performance and efficiency, yielding lower operating temperatures and reduced cooling requirements. This translates into longer service intervals and improved system availability in temperature-variable facilities. The dual primary configuration of 240/480V and secondary 120/240V provides flexible voltage conversion for mixed-supply environments, simplifying installation and reducing the need for additional transformers. Encapsulation enhances safety by reducing arcing risk and simplifying compliance with clean-room or harsh-environment standards. Overall, the S20N11E05XCU supports easier procurement, faster deployment, and measurable total cost of ownership improvements.

FAQs
The S20N11E05XCU is a 1-phase transformer with primary windings rated for 240/480V and secondary windings rated for 120/240V. This configuration enables flexible cross-connecting to common facility power rails while maintaining a compact footprint. It is well-suited for control panels and machines that operate across multiple supply voltages, reducing the need for additional step-down components.
Encapsulation protects the windings from moisture, dust, and contaminants that can degrade insulation and cause arcing or thermal faults. This leads to longer mean time between failures (MTBF), lower maintenance requirements, and safer operation in damp, dusty, or outdoor spaces. For panel builders, encapsulation simplifies compliance with enclosure cleanliness and ingress protection expectations.
Yes. With a 5 kVA single-phase rating and 120/240V secondary, the S20N11E05XCU comfortably powers relays, PLCs, sensors, and small drives in machine-tool and processing panels. Its encapsulated design helps ensure consistent performance in environments subject to dust, humidity, and temperature fluctuations, while copper windings support efficient energy transfer and reduced heat buildup.
Certifications can vary by region and installation. Common targets include CE marking for Europe and UL/CSA listings for North America, along with RoHS compliance. For this specific model, the catalog notes that certifications are provided by the manufacturer, so confirm with Eaton or your distributor to align with local regulatory requirements and installation standards.
Encapsulated transformers like the S20N11E05XCU typically offer lower maintenance due to reduced ingress concerns and more robust insulation. The 5 kVA rating supports reliable operation of auxiliary systems, potentially reducing downtime and extending service life for control panels. Copper windings improve efficiency, contributing to energy savings and lower cooling costs over the unit’s lifetime.
