With a 10 kVA rating, the S20N11S10SS4X provides reliable, isolated power for control panels and automation equipment. The encapsulated design minimizes footprint while delivering consistent secondary voltage under fluctuating line conditions. Designed for factory environments, it supports PLC feeds, HMIs, and sensor networks with predictable performance. Its UL Listed certification further assures safety and compliance across installations. The unit's 240/480 V input and 120/240 V output simplify wiring in standard power distributions. Enclosure and environmental protection ensure reliability in challenging sites. The unit uses a rugged NEMA 3R enclosure and Grade 304 stainless steel construction, with catalog notes indicating NEMA 4X compatibility for enhanced corrosion resistance in outdoor or washdown areas. This protection reduces the need for frequent maintenance, minimizes downtime, and keeps control power available in harsh environments. Electrical specifications are straightforward for engineering teams. The transformer supports 60 Hz operation with a primary of 240 V or 480 V and a secondary of 120/240 V, without taps to adjust. This simplicity lowers wiring errors and accelerates panel wiring while ensuring consistent performance under load. Material choices and physical design support installation and lifecycle cost. Aluminum windings reduce weight and facilitate handling, while the 190 lb package remains robust for demanding applications. The design supports safer hoisting with common rigging and aligns with standard enclosure footprints. Warranty and compliance deliver clear business value. UL Listed certification confirms electrical safety, and Eaton’s policy provides one year from installation or 18 months from shipment, whichever occurs first. This combination reduces risk, shortens procurement cycles, and supports predictable total cost of ownership. Compatibility with common power distribution architectures simplifies engineering design, and its non-tapped primary reduces confusion during wiring. Field engineers appreciate straightforward mounting and the indoor-outdoor readiness for both control rooms and remote equipment.

FAQs
Mount the unit in a compliant enclosure with adequate clearance for ventilation and wiring access. Use a stable base or cabinet compatible with its 11 by 16 by 14 inch footprint and ensure connector access. For field installs, follow standard power distribution practices and apply lockout-tagout procedures to prevent accidental energization.
Key specs include a 10 kVA rating, single-phase operation at 60 Hz, primary voltages of 240 V or 480 V, and a secondary of 120/240 V. The windings are aluminum, and the unit is UL Listed. The design supports reliable control power with a 115 °C rise rating under load conditions.
Yes. The S20N11S10SS4X is designed for indoor-outdoor use with enclosure options that provide protective ratings. Catalog notes cite Grade 304 stainless steel enclosure with NEMA 4X corrosion resistance capability, while the base enclosure offers NEMA 3R protection for general outdoor and damp environments, minimizing maintenance and downtime.
The transformer carries UL Listed certification, confirming electrical safety. Eaton’s warranty policy provides one year from installation or 18 months from shipment, whichever occurs first, offering protection against manufacturing defects and supporting uptime across plant operations.
The unit’s encapsulated design and non-tapped primary simplify wiring, reducing commissioning time and risk of miswiring. Aluminum windings lower weight and handling effort, while a robust enclosure minimizes maintenance needs. These factors translate to reduced downtime, longer asset life, and a lower total cost of ownership.
