Selling Policy 25-000 - Distribution and Control Products and Services
The S20N11S07CUS64X offers a single-phase 7.5 kVA general-purpose encapsulated transformer with copper windings, delivering efficient power conversion for control panels and automation equipment. The feature translates into a tangible business impact: dependable performance under load and lower energy losses thanks to copper windings, enabling more predictable operation in demanding environments and reducing downtime. This transformer is ideal for 240/480 V primary to 120/240 V secondary configurations, supporting a wide range of motor starters, PLC power supplies, and instrumentation circuits in machinery and process systems. Its indoor-outdoor suitability, reinforced by a NEMA 4X enclosure, means fewer enclosure-related failures and simpler field deployments in outdoor locations or washdown areas. The 60 Hz rating ensures compatibility with standard U.S. power systems, while the fixed tap size (none) simplifies installation and minimizes setup errors. The enclosure, available in a 316 stainless steel version per catalog notes, adds corrosion resistance for coastal or harsh environments, further extending service life and reducing maintenance costs. Finally, Eaton’s warranty policy provides coverage from shipment or installation, supporting total-cost-of-ownership considerations for OEMs and maintenance teams. In practice, engineers can count on consistent voltage transformation, compact footprint, and straightforward integration with existing power distribution schemes, accelerating project timelines and improving panel reliability. The S20N11S07CUS64X aligns well with industry-standard control architectures and complements broader Eaton power management ecosystems for scalable automation.

FAQs
The S20N11S07CUS64X is designed for standard control panels and automation equipment. Install within a NEMA 4X enclosure, connect the primary to 240 or 480 V and the secondary to 120/240 V. Ensure proper wiring polarity and secure mounting to a rigid panel surface. The unit’s fixed taps simplify wiring and reduce configuration errors, while copper windings help minimize losses during operation.
This transformer features a 240 V or 480 V primary and a 120/240 V secondary, operating at 60 Hz. This combination supports common industrial control circuits, PLC power supplies, and motor control applications with a single-phase power path, enabling straightforward integration with existing electrical infrastructure.
Yes. The unit is designed for indoor-outdoor use with a NEMA 4X enclosure rating. Catalog notes indicate a 316 stainless steel enclosure option, which provides enhanced corrosion resistance for challenging environments such as coastal facilities or washdown areas, helping to extend service life and reduce maintenance requirements.
Eaton provides a warranty under Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This aligns with typical OEM support practices and helps mitigate risk during commissioning and early operation, giving maintenance teams confidence in uptime and service planning.
The transformer occupies a footprint approximating 9.89 inches in length, 16 inches in height, and 10.38 inches in width. While listed weight shows 0.001 lb in the data, it’s best to confirm final shipping weight with the supplier. These dimensions support compact installations in control panels and equipment rooms, facilitating easy integration with existing layouts.
