FAQs

For proper installation, plan for the 1085 lb weight, ensure adequate mounting space in a NEMA 2 enclosure, provide proper vibration isolation, and implement correct grounding. Pay attention to tap settings and ensure clearances around the tank and cooling paths. The unit is rated for 60 Hz and marine-duty use, so align with shipboard electrical practices.
The transformer provides taps: 1 at +5% FCAN, 2 at āˆ’5% FCBN, and 2 at +2.5% FCAN with 4 at āˆ’2.5% FCBN. Adjusting taps helps compensate supply variations, maintain voltage regulation under load changes, and reduce voltage drop across feeders. Use precise measurements and consult derating guidelines to avoid overstepping core limits.
Yes. The RT20P11F99CUEE is ABS Certified and UL Listed, with NEMA TP-1 efficient cataloging, designed for marine-duty DS-3 single-phase service. These certifications support compliance with maritime codes and energy-efficiency standards, making it suitable for shipboard power systems, offshore platforms, and regulated industrial installations.
The transformer carries Eatonā€™s standard warranty: one year from installation or eighteen months from shipment, whichever occurs first. Copper windings and robust construction reduce field maintenance. Regular checks should include insulation integrity, enclosure sealing, and tap position verification to ensure long-term reliability in demanding environments.
Industries include marine, offshore, and heavy industrial facilities requiring stable 240 x 480 V to 120/240 V transformation. It supports distribution panels, shipboard substations, and equipment rooms where space is at a premium and rugged, vibration-tolerant, ready-to-install transformers are essential for uninterrupted operation.
