FAQs
The RT20P11F1516CU is designed for panel mounting in harsh marine environments. Plan for a ventilation-friendly location to accommodate air flow around copper windings and maintain thermal performance. Verify the NEMA 2 enclosure rating and WS11 weather shield compatibility, ensure correct mounting clearance, and wire to the 240 x 480 V primary with 120/240 V secondary per the 60 Hz specification. Include the voltage-tap scheme in the wiring diagram to support field voltage regulation.
Yes. The RT20P11F1516CU is a single-phase transformer with a 240 x 480 V primary and a 120/240 V secondary, designed for 60 Hz operation. Its tap options (+5%, -5%, +2.5%, -2.5%) enable voltage regulation to compensate for supply fluctuations. This makes it suitable for shipboard power distribution and control panels requiring stable voltages across varying loads.
The RT20P11F1516CU is UL Listed and ABS Certified, with DOE 2016 Efficient notes. UL Listed confirms electrical safety compliance, while ABS Certification supports maritime regulatory acceptance for shipboard equipment. DOE 2016 Efficient ensures energy efficiency. These certifications reduce regulatory risk, simplify procurement for marine projects, and demonstrate readiness for coastal and offshore installations.
The transformer provides taps at 1 at +5% FCAN, 2 at -5% FCBN, and 2 at +2.5%/4 at -2.5% FCAN/FCBN, enabling precise voltage regulation across changing loads. This capability stabilizes critical equipment, minimizes nuisance tripping, and improves overall system uptime in marine and offshore power distribution where input voltages can drift due to generator loading or shore power swings.
Eaton offers a one-year warranty from installation or 18 months from shipment, whichever occurs first. The copper windings, robust enclosure, and 15 kVA rating contribute to reliable long-term performance with lower maintenance needs. This translates to reduced downtime, predictable maintenance budgeting, and improved return on investment for mission-critical marine and industrial applications.
