Eaton N48M28F75EELS45 Transformer - UL Listed
Part Number: N48M28F75EELS45
Quick Summary
The Eaton N48M28F75EELS45 transformer provides nonlinear ventilated power conversion for 480 V to 208Y/120 V in industrial plants. Facility teams face noise, harmonics, and slow approvals; this transformer reduces these issues with 45 dB sound, stable regulation, and UL/NEMA TP-1 certification. UL Listed and NEMA TP-1 compliant, with optional WS19 weather shield, support indoor and outdoor installations. Its 75 kVA three-phase rating at 480 V primary and 208Y/120 V secondary, 60 Hz, and taps at +2.5% and -2.5% enable precise distribution. With aluminum windings, frame 916A, 823 lb weight, and a 25-000 warranty, you reduce lifecycle risk and simplify maintenance planning.

Eaton Specification Sheet - N48M28F75EELS45
K-Factor nonlinear design with ventilated cooling adapts to harmonic-rich loads, reducing overheating risk and extending transformer life. In data centers and industrial facilities with switching power supplies, this translates to higher reliability and fewer unforeseen outages. The 75 kVA three-phase rating, 480 V primary and 208Y/120 V secondary, at 60 Hz, supports scalable power distribution for growing loads and multiple duty cycles. Tap adjustments at +2.5% and -2.5% provide voltage regulation to keep critical equipment within tolerance, reducing nuisance tripping and improving process stability. Low sound emissions of 45 dB combined with electrostatic shielding and WS19 weather protection enable outdoor installs and close-quarters mounting without noise penalties. Aluminum windings and a rugged 916A frame enhance heat dissipation and mechanical durability for long service life in harsh environments. The unit ships with documented Eaton specifications and a one-year installation warranty or 18 months from shipment, whichever comes first, lowering procurement risk and simplifying service planning.

FAQs
The unit uses a rugged 916A frame and weighs about 823 lb, designed for mounting in standard electrical rooms or integrated with weatherized enclosures using the WS19 weather shield option. Its dimensions fit typical transformer footprints, and its enclosure-friendly form factor simplifies alignment with racks, switchgear, and protection devices.
This transformer delivers 75 kVA at 480 V primary and 208Y/120 V secondary, operates at 60 Hz, and provides three-phase power. The dual-voltage capability supports load diversity and easier integration with existing 480 V distribution schemes and 208/120 V equipment.
Yes. It is UL Listed and NEMA TP-1 compliant, which confirms safety and energy efficiency standards for power transformers. The optional WS19 weather shield expands applicability to outdoor environments, while the low-noise 45 dB rating supports sensitive workspaces and proximity to occupied spaces.
Taps are set at 2 at +2.5% and 4 at -2.5%, allowing voltage adjustment to compensate for supply variations and loading. Proper tapping during commissioning helps maintain a stable 208Y/120 V secondary, minimizes voltage drop on long feeder runs, and reduces risk to sensitive equipment.
The transformer carries a one-year warranty from installation or eighteen months from shipment, whichever occurs first. With aluminum windings, a robust 916A frame, and UL/NEMA TP-1 compliance, maintenance cycles are predictable. Regular thermal imaging, insulation checks, and enclosure integrity inspections are recommended for long-term reliability.
