Eaton RT20P11F3716CUTR General purpose ventilated transformer - UL Listed
Part Number: RT20P11F3716CUTR
Quick Summary
The Eaton RT20P11F3716CUTR general purpose ventilated transformer powers marine-duty electrical systems with reliable 1-phase operation. Engineers often struggle with limited tap options and overheating under fluctuating loads, leading to voltage drift and unexpected downtime. This unit provides precise taps (+5%/−5% with additional +2.5%/−2.5% options) and an 115 °C rise, supporting stable performance in harsh environments. UL Listed certification, DOE 2016 Efficient notes, and a rugged NEMA 2 enclosure reinforce compliance and durability in coastal and offshore facilities. By combining copper windings with a 60 Hz rating and a 37.5 kVA output, it delivers consistent power while helping reduce energy waste and maintenance costs, aligning with reliability and TCO goals for your plant operations.

FAQs
Install with the NEMA 2 enclosure in a dry, accessible space and ensure proper clearances for the 818 frame and 450 lb weight. Use the recommended wiring connection 3XA37R and observe the 60 Hz, 240 x 480 V primary and 120/240 V secondary configuration. Verify the WS11 weathershield is used when mounting in exposed locations to maintain enclosure integrity.
The transformer provides taps at 1 at +5% FCAN, 2 at −5% FCBN, 2 at +2.5% FCAN, and 4 at −2.5% FCBN. These taps allow precise voltage regulation to counteract supply fluctuations, reducing voltage distress for sensitive loads and minimizing nuisance trips in control panels and motor drives.
Yes. The unit is UL Listed, ensuring safety certification for installation in North American facilities. It also notes DOE 2016 Efficient compliance, reflecting reduced energy losses in line with contemporary efficiency standards while delivering dependable performance at 60 Hz.
Ideal for offshore platforms, shipboard electrical rooms, and industrial panel boards needing 240/480 V to 120/240 V voltage transformation. Its 37.5 kVA rating supports medium-scale loads, and the copper windings coupled with a 115 °C rise enable reliable operation under continuous duty.
Copper windings and a robust 115 °C rise design reduce insulation wear and improve longevity, lowering maintenance costs. The DOE efficiency and UL certification support energy savings and regulatory compliance, while a one-year warranty and Eaton’s service policy underpin total cost of ownership and long-term ROI for capital projects.
