Eaton S48N25S03 General-Purpose Transformer - UL Listed

Encapsulated construction with an aluminum coil resists moisture and dust while improving thermal management. This design minimizes leakage paths and helps maintain windings at safe temperatures in challenging plant conditions. The result is lower maintenance costs and extended service intervals, reducing downtime on critical lines. Technicians report easier inspection and cleaning because the sealed enclosure keeps internal components cleaner. Ideal for control panels near conveyors and robotic cells where reliability matters most. The aluminum winding contributes to robust field-performance and simpler handling during installation.NEMA 3R enclosure provides indoor-outdoor protection against rain, dust, and incidental impact. This rugged protection translates into fewer weather-related faults in outdoor equipment rooms or dockside installations, enabling compliant operation across shifts. For retrofit projects, the enclosure simplifies site planning and reduces the need for additional weatherproof upgrades. It also supports safer operation in exposed process areas by keeping windings shielded from environmental hazards. The combination of protection and compact form factor helps maintain consistent performance in demanding environments.Three kilovolt-ampere (3 kVA), 60 Hz, single-phase operation with a 480 V primary and 220 V secondary delivers the required power without oversizing. This configuration provides ample headroom for PLCs, relays, and small drives while keeping the transformer footprint compact. By matching common automation loads, it minimizes panel space and reduces wiring complexity during installation. The 115 °C rise rating offers a comfortable margin for continuous operation in warm environments. Its 8 x 14.25 x 7.69 inch footprint and 66 lb weight support straightforward mounting and service on busy production lines.Fixed wiring connection 511AF and no taps simplify field wiring and reduce commissioning time. Eliminating taps lowers the risk of mis-wired configurations and voltage mismatches during startup. Engineering teams can rely on a consistent, repeatable wiring scheme across multiple panels, accelerating procurement and installation. The design also facilitates plug-and-play compatibility with standard control-system components and quick replacements during maintenance. For new builds, fixed connections streamline schematic development and training for technicians.UL Listed certification and Weathershield indoor-outdoor design support regulatory compliance and reliability in challenging environments. The UL mark provides confidence for procurement, quality audits, and customer specifications, while indoor-outdoor capability reduces the need for separate enclosures or weatherproof upgrades. The compact footprint and fixed connections enable faster project execution and easier stocking for maintenance teams. Overall, the transformer offers protection, performance, and ease of installation that contribute to lower total cost of ownership over its lifetime.
