FAQs
The N48M28B30EEP2 is a three-phase transformer rated for 480 V primary and 208Y/120 V secondary, mounted in a 912B frame. Its 16.5 in depth and 30 in height support common installation footprints, with aluminum windings and WEATHERSHIELD options enabling outdoor placement. Ensure panelboard taps and enclosure clearances meet OEM guidelines and local codes for UL-listed equipment.
This transformer features a K-Factor nonlinear design and 80 °C rise, paired with electrostatic shielding to minimize interference with sensitive equipment. The 60 Hz operation and 30 kVA rating support stable voltage to drives and power electronics, reducing distortion-related heating and improving reliability in modern manufacturing cells and data-center style control rooms.
Industries with heavy motor loads, such as packaging, material handling, and process automation, gain from the 30 kVA capacity and robust protection. Applications include control panels, machine rooms, and outdoor distribution where a compact, rugged, code-compliant transformer is needed to maintain power quality for relays, PLCs, and drives.
The unit is UL Listed and NEMA TP-1 compliant, confirming safety and efficiency for industrial distribution. The electrostatic shielding and WS38 weathershield option support operation in harsher environments, while the 80 °C rise rating ensures performance remains within spec under typical ambient conditions.
The N48M28B30EEP2 uses aluminum windings, reducing weight and simplifying installation. UL/NEMA compliance lowers compliance risk, and a standard warranty aligns with Eaton policies. While long-term savings come from reduced energy losses and lower cooling needs in non-linear applications, ROI improves with extended component life and minimized downtime in high-demand lines.
