225 kVA capacity with a 480 V primary and 208Y/120 V secondary provides the right balance of power and footprint for modern marine electrical networks. This three-phase transformer maintains stable outputs across load swings, reducing nuisance trips and equipment wear on critical systems. Designed for marine duty, it supports compact installation under deck or in equipment rooms without compromising protection. Copper windings deliver lower copper loss and better thermal performance, enhancing reliability in confined engine rooms and contributing to overall efficiency. Rated to 115°C rise, it maintains operation in harsh environments and aligns with NEMA TP-1 efficiency expectations. Voltage taps at +2.5% and -2.5% enable on-site voltage fine-tuning to compensate for line impedance and fluctuating input conditions, reducing flicker risk and improving equipment performance. Installation is straightforward with standard busbar connections and factory documentation. Enclosure is NEMA 2 with WS34 weather protection, framed in a 917 housing for reliable installation in tight spaces, and it supports easy retrofits where space and weight constraints limit transformer choices. Warranty of Eaton’s standard policy provides 1 year from installation or 18 months from shipment, reducing risk and aiding maintenance planning. Eaton’s in-field support and service tooling further streamline troubleshooting and preventive maintenance, delivering measurable ROI through longer intervals between servicing and reduced downtime.
