Eaton N29M28T75EELS45 Transformer - UL Listed
Part Number: N29M28T75EELS45
Quick Summary
Eaton N29M28T75EELS45 is a K-Factor nonlinear ventilated transformer for three-phase power distribution. Engineers face harmonics, heat, and noise that erode efficiency and increase lifecycle costs if the wrong device is chosen. UL Listed, NEMA TP-1 compliant, and designed for a 150°C rise with a 200°C insulation system, it provides reliable performance. This solution supports efficient power management with a 75 kVA rating, 208 V input, and 208Y/120 V output for modern facilities. Beyond compliance, its low sound profile and robust construction help facilities meet safety and uptime goals while reducing lifecycle costs. The 2 at +2.5% and 4 at -2.5% taps enable site harmonics compensation and voltage fine-tuning during commissioning.

Eaton Specification Sheet - N29M28T75EELS45
Feature → Business Impact → Application: The K-Factor nonlinear design handles harmonic currents typical in modern facilities, reducing voltage distortion and improving transformer life, which lowers maintenance costs and improves equipment uptime in data centers and manufacturing lines. This translates to more predictable power quality for sensitive loads and overall system reliability. Feature → Business Impact → Application: A 75 kVA three-phase rating provides scalable headroom for expanding loads while maintaining compact footprint and manageable panel loading in control rooms and switchgear rooms. Installers gain flexibility in panel design and routine maintenance windows, supporting phased upgrades without wholesale rewiring. Feature → Business Impact → Application: Voltage tapping with 2 at +2.5% and 4 at -2.5% enables precise voltage regulation on site, reducing transformer overheating and ensuring stable equipment operation under supply variations. This is particularly valuable for sensitive PLCs, drives, and instrumentation in industrial plants. Feature → Business Impact → Application: Aluminum coil and 916A frame deliver durability and corrosion resistance with a robust footprint that suits floor- or cabinet-mounted installations, easing procurement and dispatch while supporting long service life in harsh environments. Feature → Business Impact → Application: UL Listed and NEMA TP-1 compliance, coupled with a 45 dB low sound profile and 150°C rise, simplify regulatory approval and permit processes while minimizing acoustic impact in occupied spaces and data centers. Feature → Business Impact → Application: Weathershield WS19 and electrostatic shielding enhance reliability in challenging environments, enabling outdoor or exposed indoor installations with improved moisture and dust protection, reducing preventive maintenance needs and extending service intervals.

FAQs
This transformer weighs 916 lb and has overall dimensions of 28.22 in wide, 23.42 in deep, and 48.56 in tall, so plan for proper hoisting and a fixed mounting location. It operates at 60 Hz with a 208 V primary and 208Y/120 V secondary, and requires adequate ventilation and clearances as defined by safety guidelines and the WS19 weather shield if installed outdoors.
The K-Factor nonlinear design helps manage harmonic currents common in switch-mode power supplies and control loads, reducing voltage distortion and overheating. This improves reliability in dense panels and extended equipment life. It pairs with generous insulation and a controlled temperature rise to support critical loads in data centers, manufacturing lines, and industrial controls.
Yes. The N29M28T75EELS45 is UL Listed and NEMA TP-1 compliant, confirming adherence to safety and efficiency standards. Catalog notes also indicate low sound at 45 dB and a 150°C rise, making it suitable for regulated environments such as controlled data rooms, service bays, and manufacturing floors.
Ideal for data centers, industrial control panels, and manufacturing floors requiring stable 208 V distribution with a 208Y/120 V secondary. Its 75 kVA rating supports scalable loads while maintaining compliance with safety and acoustic standards. The tap changes allow voltage fine-tuning during commissioning, reducing integration risk in dynamic facility environments.
Warranty is one year from installation or eighteen months from shipment, per Eaton policy 25-000. Support includes access to specification sheets, catalogs, and Eaton service resources. For on-site commissioning or preventive maintenance, authorized technicians can assist with installation, testing, and ongoing performance optimization.
