Eaton MV24M12F45CUEE General purpose ventilated transformer - 3-phase Marine-duty DT-3
Part Number: MV24M12F45CUEE
Quick Summary
The Eaton MV24M12F45CUEE is a general purpose ventilated transformer for marine-duty, 3-phase power distribution. In vessel and offshore settings, voltage stability and reliability are critical, especially under long feeder runs and vibration. This model supports voltage tuning with taps to compensate drops and maintains consistent output for sensitive equipment. Certifications such as CE and other regional regulatory approvals are commonly pursued; confirmation of enclosure IP ratings and SIL considerations should be coordinated with the manufacturer for your installation. With copper windings and an 115°C rise rating, it delivers durable performance in harsh environments while enabling flexible 240 V to 120 V distribution. It also supports rapid deployment in marine and industrial power systems, promoting uptime and compliance.

Feature: 45 kVA, 240 V to 120 V, 3-phase general purpose transformer. Benefit: Delivers reliable, scalable power for heavy loads on ships and offshore facilities, reducing the need for multiple smaller transformers and improving panel efficiency. Application: Ideal for marine-duty electrical distribution where consistent 120 V secondary is required from a 240 V feeder. Feature: Ventilated cooling with 115°C rise rating. Benefit: Enhanced thermal margin lowers the risk of derating under peak loads, extending service life and lowering maintenance frequency. Application: Suitable for continuous duty in humid, salt-affected environments typical of vessels and offshore platforms. Feature: Tap changer options (2 at +2.5%, 4 at -2.5%). Benefit: Voltage regulation to compensate for line drop and voltage drop across long feeders, reducing voltage excursions and improving equipment performance. Application: Quick, in-field adjustments during installation or after load changes. Feature: Copper windings. Benefit: High conductivity and robust thermal stability translate to improved efficiency and durability, contributing to lower operating costs over the lifecycle. Application: Preferred in critical power paths where reliability and heat management are paramount. Feature: Marine-duty DT-3 specification. Benefit: Enclosure and construction tailored for harsh maritime environments, supporting regulatory expectations and long-term uptime. Application: Offshore vessels, ships, and coastal facilities require rugged, compliant transformers; this unit helps meet those demands while simplifying procurement.

FAQs
The MV24M12F45CUEE provides a 240 V primary and a 120 V secondary. It is rated for 45 kVA and is a 3-phase unit, with copper windings and a DT-3 marine-duty design. It also includes voltage taps to fine-tune output when line conditions vary, specifically 2 taps at +2.5% and 4 taps at -2.5%.
The taps (+2.5% and -2.5% with 2 and 4 positions, respectively) allow you to compensate for voltage drop along feeders and minor load changes, keeping secondary voltage within tolerance. This reduces the need for external regulators, improves equipment performance, and supports stable operation in remote marine or offshore installations.
Yes. The MV24M12F45CUEE is specifically described as a marine-duty transformer with a DT-3 rating, designed to handle the harsh conditions found in ships and offshore facilities. The copper windings and ventilated design contribute to reliable operation under vibration, humidity, and salt exposure common in marine environments.
Plan for adequate ventilation and clearance around the transformer, ensure correct 3-phase wiring from 240 V mains to 120 V distribution, and select protective devices sized for 45 kVA. Verify enclosure type and potential corrosion protection for marine environments, and coordinate with Eaton for any region-specific certifications or mounting standards.
Copper windings deliver enduring conductivity and thermal performance, reducing losses and improving efficiency. The 115°C rise rating provides a generous thermal margin, supporting longer service intervals under peak loads. The 2/4 tap options simplify ongoing voltage regulation, reducing corrective maintenance and enabling stable uptime for critical marine and industrial power paths.
