Eaton RV48M28T7516CUSB Breaker-integrated transformer - UL

The RV48M28T7516CUSB employs copper windings and a 75 kVA three-phase design to deliver high reliability with low losses, translating to measurable energy efficiency gains and reduced operating temperatures in control panels. This feature supports DOE 2016 requirements while enabling tighter enclosures and safer operation in continuous duty environments. The NEMA 2 enclosure and floor-or-wall mounting provide flexible installation and easier retrofits in existing plants, reducing floor space and simplifying service access for preventive maintenance. Copper windings paired with a 150 °C rise insulation rating improve thermal tolerance, extending transformer life under demanding loads and temperature fluctuations. The transformer includes an electrostatic shield and a secondary MCCB integration (JGE3250FAGC), which streamlines wiring, enhances short-circuit protection, and shortens panel assembly time. Tap settings of +2.5% and -2.5% enable precise voltage regulation to compensate for site fluctuations, minimizing equipment wear and improving process stability. With a 60 Hz frequency rating and 480 V to 208Y/120 V secondary, it is well-suited for machine tools, packaging lines, and automation skids in manufacturing environments. The 24 in depth, 30.5 in width, and 51.5 in height footprint balance capacity with practical installability, supporting standard shelving, rigs, and maintenance clearances. The unit’s electrostatic shield, K-factor 1 rating, and WS66 weather shield consideration add ruggedization for controlled environments, while the UL Listed certification confirms conformance to safety standards for electrical protection and circuit control applications. Overall, the RV48M28T7516CUSB minimizes lifecycle costs through improved efficiency, modular integration, and installation flexibility that align with modern plant modernization programs and energy-compliance objectives.
