Eaton Specification Sheet - N48M28T09CU
The N48M28T09CU uses a K-13 design that delivers robust fault tolerance and predictable voltage performance, reducing nuisance outages and improving control reliability in automated lines. The copper windings provide superior conductivity and long-term durability, translating into lower energy losses and cooler operation in high-current applications. Its ventilated construction enhances heat dissipation, which supports consistent performance in crowded switchgear racks and minimizes thermal derating during peak loads. The unit is ship-ready for standard enclosures and features a 60 Hz frequency rating, reinforcing compatibility with common plant electrical systems. Tap options (+2.5% FCAN and -2.5% FCBN) enable fine voltage compensation at the point of use, reducing field adjustments and improving overall system stability. The WS38 weathershield option and frame 912B sizing simplify outdoor or harsh-indoor installations, while electrostatic shielding adds an extra layer of protection for sensitive equipment. Warranty alignment with Eaton policy provides predictable service, and UL Listed certification reinforces compliance across industrial environments. In practice, installers gain a straightforward path to reliable power conversion with minimal customization, while maintenance teams benefit from clear accessibility and proven long-term performance.
