Totally enclosed non-ventilated design mitigates dust ingress and moisture exposure, reducing maintenance and downtime in harsh environments, which translates to lower lifecycle costs and fewer panel rebuilds. This feature supports reliable operation in factories, data centers, and process plants, improving uptime and safety. The 30 kVA, 60 Hz, three-phase rating ensures consistent power delivery to mid-sized automation systems, minimizing voltage drop and transformer overheating; this drives improved performance of motors and drives in manufacturing lines. Primary 480 V and secondary 480Y/277 V with taps at +5% and -5% enable easy voltage matching and adaptability to supply variations, simplifying installation and reducing field wiring adjustments in control panels and electrical rooms. Copper windings with a 150 °C rise provide durability and efficient heat dissipation, improving efficiency and reducing thermal-related losses in continuous operation. The 22 inch depth, 29 inch width, and 39.18 inch height framed by 915DN support compact footprint integration in crowded electrical spaces, making retrofits and new installations straightforward. UL Listed certification confirms compliance with electrical safety standards, supporting regulatory approvals and faster procurement cycles, while a one-year warranty from Eaton offers assurance against early life defects and service requirements. These features collectively deliver a dependable, scalable, and cost-effective power distribution solution for industrial automation and facility distribution.
