Feature → Business Impact → Application: Copper wound coils deliver low resistance and efficient current transfer, reducing losses and heat generation, which translates to improved energy efficiency and lower operating costs in continuous start-up scenarios. Application: control panels and distribution blocks in factories. Feature → Business Impact → Application: NEMA 3R indoor-outdoor enclosure provides weather-resistant protection, enabling installation in exposed or partially sheltered environments without additional housing. Application: outdoor-rated transformer installations for manufacturing yards and outdoor equipment rooms. Feature → Business Impact → Application: 10 kVA single-phase rating with 480 V primary and 120/240 V secondary delivers versatile power conversion for machine tools and processing equipment, improving panel density and reducing the need for multiple transformers. Application: machine control panels and shop floor power distribution. Feature → Business Impact → Application: 60 Hz operation with 80 °C rise allows reliable performance under typical industrial ambient conditions, supporting longer service life and predictable thermal behavior. Application: constant-load applications in moderate environments. Feature → Business Impact → Application: 524H wiring connection aligns with Eaton’s standard installation practices, simplifying wiring harness integration and reducing commissioning time. Application: retrofit projects in existing Eaton-based control architectures. Feature → Business Impact → Application: Grade 304 stainless steel enclosure note in catalog materials hints at corrosion resistance in harsh environments, contributing to lower maintenance frequency and longer mean time between failures. Application: coastal or high-humidity facilities and wash-down environments where enclosure longevity matters.

FAQs
The S48N11B10CUSS weighs about 250 lb and uses a 524H wiring connection, designed for straightforward mounting in control panels or dedicated transformer enclosures. Its NEMA 3R, indoor-outdoor rating and Grade 304 stainless enclosure notes support outdoor placement with minimal protective housing. Allow for clearances around the enclosure for ventilation and servicing, and follow Eaton’s recommended mounting practices to ensure safe, accessible connections and compliance with local codes.
This unit is a single-phase transformer with a 10 kVA rating. Primary voltage is 480 V, and secondary voltage is 120/240 V. It operates at 60 Hz and features an 80 °C rise, suitable for standard industrial environments. Wiring is designated as 524H, compatible with common Eaton control panels and distribution systems to streamline integration.
Yes. The transformer is designed for indoor-outdoor use with a NEMA 3R enclosure, providing weather resistance in exposed or semi-exposed locations. This makes it suitable for outdoor transformer pads or equipment rooms adjacent to manufacturing floors. Ensure installation follows local codes and that mounting allows drainage and ventilation as needed.
The pack carries UL Listed and CSA Certified safety marks, which validate electrical safety and conformity to recognized standards. These certifications reduce risk during audits and help meet procurement and compliance requirements for regulated facilities. The enclosure’s weather-resistant design further supports compliance in environments with moisture, dust, or temperature variation.
With copper windings, epoxy encapsulation, and a durable NEMA 3R enclosure, the S48N11B10CUSS delivers low maintenance and long service life in typical plant environments. The 1-year Eaton warranty (25-000) and up to 18 months from shipment coverage provide assurance against premature failures. The reliable performance reduces downtime, lowers replacement costs, and supports a favorable return-on-investment when used for critical control panels and power distribution.
