Eaton Specification Sheet - N48M47T75CUEE
75 kVA three-phase transformer capability supports heavy loads with high reliability, reducing voltage drop and motor wear while improving overall plant uptime. The business impact is tangible: steadier voltage reduces unexpected downtime and extends equipment life, particularly for high-torque motors and drive systems in production lines. Application-wise, this unit is well suited for manufacturing facilities, data centers, and large motor feeders where consistent power quality is critical. The optional voltage taps (+2.5% and -2.5%) enable precise regulation to match fluctuating supply conditions, minimizing voltage excursions and improving process consistency. Copper windings minimize I2R losses, delivering better efficiency and lower operating costs in continuous-operation environments. The ventilated, K-Factor nonlinear design enhances heat dissipation, supporting reliable performance in tighter electrical rooms and higher ambient conditions. Weathershield WS19 and a robust 916A frame simplify outdoor or harsh indoor installations, reducing enclosure requirements and bolstering protection against dust and moisture. Compliance with UL and NEMA TP-1 standards further reduces procurement risk and accelerates spec-to-install timelines, while the 23.42 in depth, 28.22 in width, and 48.56 in height footprint helps with layout planning in space-constrained facilities.

FAQs
The N48M47T75CUEE is a three-phase transformer with a 480 V primary and a 480Y/277 V secondary, designed for direct compatibility with common industrial motor drives and control circuits. The 75 kVA rating supports substantial motor loads, while the 60 Hz frequency ensures standard alignment with most equipment. For precise voltage matching, use the +2.5% and -2.5% taps to compensate supply variations at the panel level.
The transformer weighs 809 lb and has dimensions of 23.42 in (depth) by 28.22 in (width) by 48.56 in (height). This footprint fits typical electrical rooms and outdoor enclosures when paired with the WS19 weather shield. Weight and size should be considered for crane access, pad mounting, and room clearance to ensure safe handling during installation.
The N48M47T75CUEE is UL Listed and NEMA TP-1 compliant, with a catalog note indicating NEMA TP-1 efficiency. These certifications signal compliance with recognized safety and performance requirements, reducing procurement risk, and supporting regulatory approval for installation in industrial facilities and data centers.
This unit excels in critical power distribution tasks such as feeding large motors, motor drives, and sensitive electronics in manufacturing, processing plants, and data centers. The +/− tap capability allows tight voltage regulation in environments with fluctuating upstream voltage, while the copper windings offer efficiency advantages for continuous operation.
