Eaton N48M28F75EELS47 Transformer - UL Listed
Part Number: N48M28F75EELS47
Quick Summary
The Eaton N48M28F75EELS47 transformer is a nonlinear ventilated, three-phase power solution for industrial facilities. Engineers often struggle to balance efficiency, noise, and regulatory compliance in compact electrical rooms. UL Listed and NEMA TP-1 compliant, with low-noise performance and electrostatic shielding, help meet safety and performance standards. Designed for 480 V primary and 208Y/120 V secondary, it supports scalable data centers, automation racks, and machine halls. Businesses gain reliable power quality, predictable voltage regulation, and install-ready compatibility with standard footprints and taps. Its 75 kVA rating and 60 Hz operation align with common industrial loads, reducing the need for multiple transformers. The built-in tapping and low heat rise support longer service life and lower cooling costs in factory environments.
