Eaton Specification Sheet - N29M47F75CU
Feature: K-13 K-Factor nonlinear design with a ventilated cooling system. This configuration reduces heat buildup under harmonic-rich loads, improving reliability and extending transformer life in demanding environments. It’s particularly beneficial for automation panels, motor drives, and PLC-controlled processes where harmonic current is common. Feature: Three-phase 75 kVA rating with 208 V primary and 480Y/277 V secondary. This setup supports scalable power distribution in mid-size facilities while maintaining stable voltage profiles, reducing panel complexity and risk of under- or over-voltage events. Applications include switchgear assemblies, panel boards, and critical control rooms in manufacturing and data processing environments. Feature: Copper windings and electrostatic shield. These features lower losses and EMI coupling, improving signal integrity, sensor accuracy, and overall control performance in harsh plant environments. Ideal for robotics, CNC machines, and automated material handling where precision matters. Feature: Tap settings with 2 at +2.5% FCAN and 4 at -2.5% FCBN. On-site voltage tuning without external gear simplifies commissioning, reduces installation time, and helps maintain target voltages during startup and load swings. Feature: Frame 916A with Weathershield WS19. The compact frame and protective coating enable easy enclosure compatibility and outdoor readiness, lowering additional protective costs and enabling faster, compliant installations in exposed environments.

FAQs
When integrating the N29M47F75CU into standard control panels, verify enclosure compatibility with frame 916A and account for 48.56 in height and 28.22 in width as listed in the data. The WS19 weather shield supports outdoor or harsh-environment installations, while copper windings and electrostatic shield reduce EMI and loss. Ensure proper clearance for ventilation and easy access to taps for voltage tuning.
The K-13 nonlinear design is engineered to mitigate harmonic heating and voltage distortion by distributing the harmonic currents more effectively. This reduces hot spots, extends transformer life, and improves overall reliability in equipment with heavy drive loads or PLC-controlled processes. In practice, you’ll see steadier voltages and better sensor accuracy in automation panels.
Yes. The N29M47F75CU features Weathershield WS19 and is designed for environments where protection against dust, moisture, and corrosion is important. The rugged frame and copper windings provide durability, while the shielded construction helps meet EMI requirements in factory floors, outdoor substations, or exposed electrical rooms.
The transformer offers taps at 2 positions at +2.5% FCAN and 4 positions at -2.5% FCBN, enabling on-site voltage tuning without external equipment. Use positive taps to compensate for voltage drop along long feeds or startup transients, and use negative taps to correct for overvoltage conditions due to light loads or supply fluctuations. Check voltage under load and adjust during commissioning.
Eaton provides a warranty per policy 25-000: coverage from the date of installation for one year, or eighteen months from shipment, whichever occurs first. Support includes access to Eaton’s specification sheets and datasheets, plus UL Listed safety certification documentation. For service planning, document the frame 916A, WS19, and copper winding features to streamline future maintenance.
