Eaton RT20P11F7516CU Ventilated transformer UL listed

The RT20P11F7516CU delivers 75 kVA capacity with a 240/480 V primary and 120/240 V secondary at 60 Hz, designed for marine duty. This combination supports propulsion controls, navigation equipment, lighting, and critical instrumentation while maintaining voltage stability during load swings and shore-power transitions. Business impact: predictable performance, reduced risk of over- or under-voltage, and improved uptime for mission-critical systems. Applications include integrated power management on vessels and offshore platforms, where consistent voltage conversion is non-negotiable. Copper windings deliver high conductivity and robust thermal performance. Copper windings reduce copper losses and enable efficient cooling in warm engine rooms, extending transformer life and lowering operating costs over the lifecycle. The design supports sustained operation under demanding maritime conditions, with minimal insulation degradation and reliable short-circuit response. Applications span engine rooms and switchgear assemblies where heat and efficiency directly influence maintenance cycles and energy consumption. Tap changer capability provides flexible voltage regulation. The primary taps (1 at +5%, 2 at -5%, 2 at +2.5%, 4 at -2.5%) let technicians compensate for load variations, distance from source, and transformer aging. This feature reduces nominal voltage drift, protects sensitive equipment, and minimizes the need for external regulators during voyage or dockside operations. It is especially valuable for precision motors, control panels, and sensitive instrumentation in maritime electrical systems. Rugged enclosure and marine duty design simplify installation. The NEMA 2 enclosure offers moisture and dust protection, while the 820 frame and dimensions (23.84 in L, 24.22 in W, 42.03 in H) with a 910 lb weight define a stable footprint for shipboard mounting. This makes it easier to integrate into existing electrical rooms, reduces retrofit complexity, and supports safer maintenance access in tight spaces. Compliance and efficiency underpin procurement decisions. UL Listed and ABS Certified, along with DOE 2016 Efficient notes, reassure buyers that the transformer meets regulatory and energy-performance expectations. A one-year limited warranty (or 18 months from shipment) provides risk protection while service and spare-part availability from Eaton support channels helps minimize downtime across fleets.
