Eaton MV48M28F12CUEE Transformer - ABS Certified UL Listed
Part Number: MV48M28F12CUEE
Quick Summary
MV48M28F12CUEE is a general purpose ventilated transformer designed for marine-duty power conversion in industrial and offshore environments. Operators often struggle with voltage stability and equipment wear when venturing into harsh marine conditions; this unit mitigates these risks with copper windings, a robust NEMA 2 enclosure, and a true DT-3 three-phase design. It carries ABS marine certification and UL listed status, plus NEMA TP-1 efficient notes, signaling strong regulatory and energy-performance alignment. The 112.5 kVA rating with 480 V primary and 208Y/120 V secondary, along with 2 at +2.5% and 4 at -2.5% taps, supports precise voltage matching. For shipboard and offshore installations, this transformer delivers reliable, low-maintenance power distribution with scalable capacity.

FAQs
MV48M28F12CUEE is a marine-duty, three-phase transformer with a 480 V primary and 208Y/120 V secondary, 60 Hz operation, and copper windings. Its NEMA 2 enclosure and DT-3 design support rugged shipboard environments, while the 112.5 kVA rating aligns with common vessel load profiles, enabling seamless integration with deck and propulsion system loads.
This model carries ABS Certification and UL Listing, providing marine- and safety-regulatory confidence. In addition, NEMA TP-1 efficiency guidance supports energy-performance expectations. Together, these certifications help simplify procurement and audit processes for offshore projects.
Plan for a footprint of about 28.22 in wide by 23.42 in deep and a height of 48.56 in, with an approximate weight of 814 lb. The enclosure is NEMA 2 rated, and optional Weathershield WS19 can enhance corrosion protection. Ensure adequate clearance and secure mounting on a solid base to handle the weight and vibration inherent to marine environments.
The transformer provides taps at +2.5% and -2.5%, enabling precise voltage tuning to maintain output within tight tolerances. This reduces voltage drop on sensitive equipment, improves efficiency for varying load conditions, and minimizes nuisance trips in dynamic offshore power systems.
Warranty covers one year from installation or 18 months from shipment, whichever occurs first. Eaton’s support ecosystem includes technical datasheets, specification sheets, and access to spare parts and service programs as outlined in Selling Policy 25-000, helping optimize total cost of ownership.
