Eaton Specification Sheet - N39M28T75XCU
Feature: K-Factor nonlinear design helps manage harmonic currents and reduces transformer overheating, delivering improved reliability in high-load environments. Business Impact: Lower heat in electrical rooms translates to longer equipment life and reduced cooling costs. Application: Data centers, manufacturing lines, and process facilities benefit from stable voltages under harmonic-rich loads. Feature: Copper windings and electrostatic shielding minimize core and copper losses while reducing EMI, enabling smoother operation of sensitive drives. Business Impact: Improved efficiency and EMI compliance, lowering energy waste and shielding adjacent equipment. Application: Automation panels and motor control centers on factory floors. Feature: Tap size options—2 at +2.5% FCAN and 4 at -2.5% FCBN—offer voltage flexibility for fluctuating supply conditions. Business Impact: Faster commissioning and tighter voltage control across loads. Application: Panelboards and distribution centers serving mixed-voltage equipment. Feature: 75 kVA, 400 V primary, 208Y/120 V secondary in a 3-phase, 50-60 Hz system aligns with standard industrial architectures. Business Impact: Simplified integration with existing standards reduces design risk and procurement complexity. Application: Industrial automation, machine shops, and data centers require consistent secondary voltages. Feature: Weather shield WS19, rugged frame 916A, and 150 °C rise tolerance support harsh environments and long service life. Business Impact: Lower maintenance intervals and higher uptime. Application: Outdoor cabinets, exposed facilities, and manufacturing floors with elevated ambient temperatures.

FAQs
Ensure correct voltage class (400 V primary, 208Y/120 V secondary), verify panel clearance for the 28.22 in width and 48.56 in height, and follow UL-listed installation guidelines. Use proper shielded grounding and install the WS19 weather shield when applicable to protect from environmental exposure.
Three-phase configuration at 50-60 Hz, 75 kVA rating, 400 V primary, 208Y/120 V secondary, copper windings, frame 916A, and taps at +2.5% FCAN and -2.5% FCBN, with 150 °C rise for thermal tolerance.
Yes. The K-Factor nonlinear design is built to mitigate harmonic currents, reducing overheating and maintaining voltage quality in equipment such as drives and PLCs, while enabling reliable operation under heavy loading.
This model is UL Listed, indicating compliance with North American electrical safety standards. Certification supports safer installation, easier approvals in regulated environments, and alignment with procurement specifications for industrial facilities.
The combination of copper windings, effective heat management, and robust weather shielding reduces energy losses and downtime. This leads to lower maintenance costs and longer service life in demanding applications.
