Eaton N43M28T33CUEE Nonlinear ventilated transformer - 150C
Part Number: N43M28T33CUEE
Quick Summary
The Eaton K-Factor nonlinear ventilated transformer is engineered for robust power conditioning in demanding industrial environments. This design helps address heat, harmonics, and efficiency losses that plague high-load systems, reducing maintenance cycles and extending asset life. While specific certifications should be confirmed with the manufacturer, the product is noted for NEMA TP-1 efficiency and electrostatically shielded construction to mitigate EMI. With 416 V primary and 208Y/120 V secondary outputs, copper windings, and precise tap options, it delivers reliable voltage regulation under load. The result is improved plant uptime, easier compliance reporting, and measurable energy savings across the power distribution network.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: K-Factor nonlinear design manages harmonic currents more effectively, reducing overheating and improving system reliability in facilities with nonlinear loads such as drives and furnaces; this translates to lower energy waste and longer transformer life in manufacturing lines and processing plants. Feature → Copper windings and 60 Hz operation provide durable electrical paths with high conductivity, delivering consistent voltage regulation under peak demand for critical equipment like CNC machines and packaging lines. Feature → 416 V primary and 208Y/120 V secondary enable standard industrial power distribution, simplifying panel design and minimizing rework during retrofit projects in warehouses and data centers. Feature → Tap changer with 2 at +2.5% and 4 at -2.5% supports precise voltage adjustment, reducing voltage dips and protecting sensitive controls in automation cells and robotic workstations. Feature → Electrostatic shielding and WS35 weathershield enhance EMI control and environmental resilience, supporting compliance and performance in challenging locations such as outdoors, outdoor switchyards, or exposed industrial interiors. Feature → 300 kVA three-phase rating aligns with mid-to-large power conditioning needs, enabling scalable distribution without multiple transformers, cutting installation footprint and lifecycle costs in process lines and packaging facilities. Feature → NEMA TP-1 efficient notes and a high insulation system support ongoing efficiency targets and lower cooling requirements, simplifying thermal management in continuous operation environments. Feature → Winding connection 292E and frame 919E facilitate straightforward installation and compatibility with common switchgear, aiding engineers during field retrofits and new builds. Feature → Weathershield WS35 and copper windings provide reliability in harsh environments, reducing maintenance calls and enabling longer service intervals in mining, rail, or heavy manufacturing settings.

FAQs
Ensure wiring is configured for a 416 V primary and 208Y/120 V secondary with a 292E connection; plan for the 36.23 in depth, 75 in height, and 44.2 in width frame (919E) while allowing for maintenance clearances and access to taps (+2.5% / -2.5%).
Confirm 60 Hz frequency, 300 kVA power rating, three-phase configuration, 416 V primary, 208Y/120 V secondary, 150 °C rise, and copper windings to ensure compatibility with your load profile and insulation system.
Yes. The K-Factor nonlinear design is specifically intended to manage nonlinear loads, reducing overheating and improving voltage regulation for drives, PLCs, and other automation equipment.
Certifications are listed as Contact Manufacturer; catalog notes indicate NEMA TP-1 efficiency. For CE, UL, or local compliance, consult Eaton directly to obtain current certifications and installation guidance.
Warranty is Eaton Selling Policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. Plan for routine inspections of copper windings and insulation performance, and reference the 150 °C rise rating for thermal management strategies.
