Eaton Specification Sheet - N48M24T75EE
K-Factor nonlinear ventilated design reduces overheating under harmonic loads, improving reliability and lifespan for motor drives and drive systems in demanding settings. This transformer’s ventilation supports continuous operation where cooling is constrained, cutting maintenance costs and downtime. The +2.5%/-2.5% taps allow voltage tuning to keep secondary voltage within tight limits, preventing nuisance tripping and equipment stress in variable supply environments. With a 75 kVA rating and 480 V to 240 V delta configuration, it fits standard MCCs and control panels, simplifying integration and reducing footprint. Aluminum coil construction and a rugged 916A frame paired with a NEMA 2 enclosure deliver robustness in indoor plants and damp facilities, while WS19 weathershield compatibility adds outdoor protection when needed. A 150 °C rise with a 200 °C insulation system provides insulation margin for high-load conditions.

FAQs
Yes. The N48M24T75EE uses a 916A frame and standard 23.42 in length, 48.56 in height, and 28.22 in width, with a 295B wiring connection. It is designed to fit typical MCCs and control panels. Plan for proper clearance around the 808 lb unit and ensure adequate cooling to achieve the 150 °C rise rating during steady-state operation.
The transformer provides 75 kVA with a 480 V primary and 240 V delta secondary, operating at 60 Hz. It offers taps at +2.5% and -2.5% to maintain secondary voltage under supply variation, and features UL Listed safety certification and an electrostatically shielded design option for enhanced performance in challenging environments.
Ideal for industrial control panels, motor drives, and power distribution equipment where harmonic content and voltage stability are concerns. The K-Factor nonlinear ventilated design reduces overheating, while the NEMA TP-1 efficiency designation supports energy compliance. It suits plant-wide power distribution and equipment that require reliable voltage regulation under fluctuating loads.
The unit is UL Listed and comes with a NEMA 2 enclosure standard. It also notes NEMA TP-1 efficiency, supporting energy-efficient operation. These certifications simplify safety compliance, damp-environment protection, and ongoing operational efficiency across industrial facilities.
Eaton provides a one-year warranty from installation or eighteen months from shipment. The robust aluminum coil, durable enclosure, and reliable cooling reduce downtime and maintenance costs, contributing to a favorable total cost of ownership for mission-critical power distribution and drive systems.
