Eaton N48M28T12AFEE Nonlinear Transformer - Fungus Proof
Part Number: N48M28T12AFEE
Quick Summary
The Eaton N48M28T12AFEE nonlinear transformer provides reliable three-phase power conversion from 480 V to 208Y/120 V for industrial facilities. Operators often struggle with voltage drift and heat buildup under fluctuating loads, risking equipment downtime. This design emphasizes NEMA TP-1 efficient fungus-proof construction, a 150 °C rise with a 200 °C insulation system, and electrostatic shielding with WS19 weather protection. With an aluminum coil, a 902 lb footprint, and a footprint suited to standard floor spaces, it supports straightforward installation and predictable maintenance, delivering long-term cost savings. In practice, this translates to higher uptime for automated lines and more stable service to critical loads.
