Ventilated cooling design improves heat dissipation under load, enabling stable performance in tight panels and reducing enclosure fan requirements. This translates to lower maintenance costs and higher uptime in continuous processing lines. A 50 kVA single-phase rating provides robust power for automation controllers, servo drives, and lighting circuits, allowing you to consolidate power supplies and simplify cabinet layouts. The NEMA 12 enclosure protects internal windings from dust and moisture, delivering long-term reliability in manufacturing floors and outdoor-adjacent facilities. Aluminum windings reduce transformer weight and improve heat transfer, making installation and service easier while contributing to lower cooling energy needs. The compact footprint fits compact switchgear and control cabinets, freeing panel space for other critical components. UL Listed certification and Eaton’s warranty policy reinforce procurement confidence and risk management for capital projects.
