Eaton N48M47T15CUEE K-Factor Transformer - UL Listed
Part Number: N48M47T15CUEE
Quick Summary
The Eaton K-Factor nonlinear ventilated transformer is designed to deliver clean, stable power conditioning for critical industrial controls. This 15 kVA, three-phase unit minimizes heat buildup and nuisance trips in demanding switchgear. Operators often struggle with heat rise, efficiency losses, and space constraints, but copper windings and enhanced ventilation improve cooling and longevity. It is UL Listed and NEMA TP-1 compliant, with catalog notes noting NEMA TP-1 efficiency. The unit supports 480 V primary and 480Y/277 V secondary, with taps for ±2.5% adjustments to fine-tune operation. For engineering teams, this translates to reliable performance, easier installation, and reduced lifecycle costs in modern power-distribution schemes.

Eaton Specification Sheet - N48M47T15CUEE
The N48M47T15CUEE is a three-phase K-Factor nonlinear ventilated transformer rated at 15 kVA, designed to soften harmonic stress and deliver stable output to sensitive loads in industrial control panels. Business impact: improved reliability and reduced maintenance due to enhanced cooling and copper windings. Application: ideal for MCCs, switchgear, and power-distribution boards where voltage distortion must be minimized. The unit uses copper windings and a rugged 912B frame, offering low impedance and durable operation; installation benefits include a compact footprint (16.5 in depth, 23 in width, 30 in height) and a total weight of 346 lb that supports secure mounting in standard enclosures. The taps (+2.5% and -2.5%) allow voltage fine-tuning to match system drift, reducing harmonics and improving efficiency in dynamic load scenarios. Compatibility with WS38 weather protection and electrostatic shielding provides added resilience in harsh environments, while compliance with NEMA TP-1 and UL Listed expectations ensures regulatory alignment. Long-tail keywords to consider include K-Factor nonlinear transformer, ventilated transformer, 15 kVA transformer, 480 V primary, 480Y/277 V secondary, NEMA TP-1 efficient, and copper-windings transformer. Warranty and serviceability considerations are strengthened by Eaton’s policy, simplifying procurement and maintenance planning for mission-critical facilities.

FAQs
Plan for a 30 in tall, 23 in wide footprint with at least proper ventilation around the unit. The 16.5 in depth and 346 lb weight require a sturdy mounting surface or enclosure that can support static loads. Use the 912B frame mounting pattern and allow clearance for taps (+2.5% and -2.5%) to enable voltage adjustments without disassembly. The WS38 weather shield and electrostatic shielding improve environmental resilience in exposed or harsh installations.
The transformer is rated for 15 kVA, 60 Hz, three-phase operation with a 480 V primary and 480Y/277 V secondary. Copper windings provide low impedance and efficient current transfer, while K-Factor nonlinear design helps manage harmonic content. The device offers taps at +2.5% and -2.5% for voltage regulation, aiding stability under fluctuating loads and improving overall power quality in control circuits.
Yes. The unit is UL Listed and NEMA TP-1 compliant, meeting recognized standards for low-voltage distribution transformers. Catalog notes also indicate NEMA TP-1 efficiency, supporting regulatory alignment in energy-conscious installations. This combination reduces compliance risk for new builds and retrofits in industrial facilities.
Ideal for critical panels, MCCs, and power-distribution configurations needing stable 480 V to 480Y/277 V conversion with harmonic mitigation. The copper windings and ventilated design improve cooling, reducing thermal wear and extending service life, which translates to lower maintenance costs and fewer unplanned outages. The selectable taps enable precise voltage control, helping minimize equipment stress and extend asset life in variable-load environments.
Eaton offers a warranty of one year from installation or eighteen months from shipment, whichever comes first, adding protection against early failures. This, combined with UL/NEMA TP-1 compliance and documented efficiency, contributes to a lower lifecycle cost by reducing downtime, simplifying procurement with standard parts, and providing predictable maintenance planning for industrial facilities.
