FAQs
Plan for a three-phase 480 V input and 208Y/120 V output, mount the unit on a compatible frame (917) with adequate ventilation, and connect primary to the 480 V bus with proper overload protection. Route the 208Y/120 V secondary to the distribution panel, using the electrostatic shield and aluminum windings to optimize safety and performance. Refer to Eaton’s datasheet and follow local code requirements for installation clearances and grounding.
The N48M28T49 employs a K-Factor nonlinear design with an electrostatic shield and aluminum windings, improving voltage regulation under harmonic currents and reducing insulation stress. This configuration enhances reliability for motor drives, welders, and other non-linear loads common in automation facilities, helping to minimize overheating and extend transformer life.
Best suited for industrial power distribution, motor drives, automated manufacturing lines, and processing equipment that introduce harmonic content. The 150 kVA rating supports moderate-to-heavy load conditions, while the 480 V to 208Y/120 V secondary provides standard utility compatibility for panel boards and distribution systems in automated environments.
This transformer is UL Listed, confirming safety and reliability for industrial use. Regional deployments may require CE or IP ratings; verify with Eaton for your specific site. The product also adheres to Eaton’s warranty policy, which covers one year from installation or eighteen months from shipment, whichever comes first.
Benefits include reduced maintenance due to robust shielding and high-quality aluminum windings, and improved uptime from better thermal management under harmonic loads. The 150°C rise rating provides headroom under peak loads, while the warranty and availability of Eaton support help reduce lifecycle risk and total cost of ownership for automation and power distribution projects.
