Eaton MV48M12F15CU General purpose Transformer - UL Listed
Part Number: MV48M12F15CU
Quick Summary
MV48M12F15CU is a general purpose ventilated transformer designed for three-phase power distribution in marine and industrial environments. Engineers often struggle with heat buildup, enclosure size, and regulatory compliance in harsh facilities. This unit is UL Listed, ABS Type Certified for marine duty, and housed in a NEMA 2 enclosure to withstand dust, moisture, and washdowns. It delivers a 15 kVA rating with copper windings, 60 Hz operation, and a 115°C rise, suitable for demanding control panels. With a 480 V primary and 120 V secondary, plus two voltage taps (+2.5% and -2.5%), installation is straightforward in standard frame footprints. The result is reliable power delivery, reduced maintenance, and lower lifecycle costs for industrial users.

FAQs
MV48M12F15CU is designed for indoor or protected indoor use in a NEMA 2 enclosure. Allow access for wiring, taps, and maintenance, and align with the 912D frame footprint. Common practice includes leaving clearance for cooling and serviceability, with attention to gate or door openings to accommodate the 206 lb weight. Follow standard Eaton mounting guidelines to ensure proper ventilation and code compliance.
The transformer provides taps at +2.5% and -2.5% to adjust the secondary voltage under load. This enables fine-tuning of output around 120 V during voltage fluctuations, helping sensitive equipment maintain performance. Use the 281B15M wiring connection per manufacturer guidelines and verify wiring changes with a qualified electrician to maintain UL and ABS compliance.
Yes. MV48M12F15CU is specified for marine duty with ABS Type Certification and a UL Listed rating, plus a rugged NEMA 2 enclosure. Its 115°C rise and copper windings support reliable operation in hot, damp, or washdown-prone spaces. For marine control panels, combining these certifications with the compact footprint simplifies regulatory clearance and installation.
MV48M12F15CU carries UL Listed certification and ABS Type Certification, indicating compliance with safety and marine industry requirements. These certifications simplify procurement and reduce risk during audits. The NEMA 2 enclosure adds environmental protection for dusty or moist environments, while copper windings and 60 Hz operation meet standard industrial expectations.
Maintenance needs are minimized by rugged construction, a 115°C rise limit, and high-quality copper windings, which reduce thermal stress and energy losses. ROI comes from improved reliability, reduced downtime, and lower replacement costs over a long service life. The unit’s standard frame and taps simplify installation, spare parts availability, and future upgrades.
