The MV48M28F22CU is a marine-duty, three-phase transformer rated for 225 kVA with a 480 V primary and 208Y/120 V secondary. Copper windings deliver high efficiency and thermal performance, while the robust frame 917 ensures compatibility with standard mounting. In marine environments, this configuration supports reliable shipboard power distribution and straightforward retrofits for existing systems. The unit provides voltage regulation through taps 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling precise compensation for line losses and generator droop, which translates to fewer equipment faults and tighter voltage control at critical loads. The NEMA 2 enclosure paired with ABS Certified UL Listed markings enhances safety compliance and corrosion resistance in demanding seaborne applications. Installation and commissioning are simplified by a compact footprint, copper windings, and Eaton’s documented best practices, delivering predictable performance for offshore facilities and heavy industries. Warranty and service support—Eaton’s 25-000 policy with one year from installation or 18 months from shipment—further reduce long-term ownership risk and maintenance planning.

FAQs
Install on a rigid base capable of supporting ~1700 lb and in a ventilated area with adequate clearance. Connect the 480 V primary and 208Y/120 V secondary per the nameplate, using the taps at +2.5% FCAN and -2.5% FCBN to compensate line losses. Follow Eaton installation guidelines and the provided datasheet for torque specs, wiring diagrams, and protective devices.
Key specs include a 225 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz frequency, copper windings, frame 917, and a NEMA 2 enclosure. It also features taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN, supporting voltage regulation across typical maritime electrical networks.
Yes. It is specifically designed as a marine-duty transformer with ABS Certified and UL Listed markings, a NEMA 2 enclosure, and copper windings to withstand humid, salt-affected environments. With 225 kVA rated capacity and a rugged build, it reliably powers critical shipboard or offshore platform loads while meeting regulatory standards.
ABS Certified and UL Listed certifications verify compliance with maritime safety and electrical standards, which reduces risk during audits and operations. The combination supports safe operation in harsh environments, while the NEMA 2 enclosure provides moisture protection essential for marine and industrial facilities.
Expect solid ROI from durable copper windings, reliable performance, and reduced downtime due to robust construction and voltage regulation capability. The quoted Eaton warranty—one year from installation or 18 months from shipment—adds assurance, while the 225 kVA rating supports load growth with scalable, low-maintenance power distribution.
