Eaton S57N48S03N Encapsulated Transformer - UL Listed

Encapsulated construction with aluminum coil provides rugged durability and weather resistance. This design minimizes moisture ingress and varnish leaks, reducing maintenance and increasing mean time between failures in harsh environments. In automation panels, the result is reliable operation with lower total cost of ownership. The NEMA 3R enclosure supports indoor-outdoor service, protecting critical components from dust, moisture, and incidental debris. This translates to fewer panel failures and longer life in outdoor or damp locations, making it ideal for outdoor substations, process lines, and machine enclosures. The 575 V to 480 V single-phase, 60 Hz, 3 kVA rating aligns with common industrial power architectures, enabling straightforward integration into control cabinets and MCCs while minimizing voltage drop and energy loss. Compact, aluminum-coil transformers offer efficient heat dissipation and long-term reliability, reducing cooling requirements and energy costs in continuous operation. UL Listed certification reinforces compliance with safety standards, streamlining procurement and reducing qualification time for OEMs and end users. The 8 in by 14.25 in by 7.69 in footprint and 64 lb weight simplify mounting, transport, and installation within dense panel layouts, supporting faster project timelines and scalable deployments in power management and distribution systems. Wiring is documented under S03173, simplifying field connections and reducing commissioning risk across industrial facilities.
