The K-Factor nonlinear ventilated design reduces harmonic distortion and heat buildup, delivering cleaner power and higher overall efficiency for non-linear loads in automation panels. This translates to reduced stray losses, cooler operation, and longer service life for sensitive drives and PLCs in machine control environments. In practice, you’ll see improved voltage stability under peak load and easier compliance with power quality requirements in modern industrial applications. Copper windings with a 75 kVA rating provide lower resistive losses and robust current handling, improving voltage regulation across the load spectrum. Business implications include lower cooling costs and extended transformer life, delivering measurable maintenance savings in demanding installations. The unit’s taps—1 at +5% FCAN, 2 at -5% FCBN, 2 at +2.5% FCAN, and 4 at -2.5% FCBN—allow precise voltage matching for sensitive PLCs and drives, minimizing regulation errors. The 150 °C rise rating indicates resilient performance in tight enclosures or higher ambient temperatures, while electrostatic shielding mitigates EMI on nearby electronics. UL Listed, NEMA TP-1 compliant, and DOE 2016 Efficient notes assure compliance, energy performance, and warranty confidence, while compatibility with Eaton’s ecosystem simplifies stocking and repair and supports a longer asset life.

FAQs
Plan for a ventilated enclosure and access for the 1056 lb unit; ensure ample clearance for copper windings, taps, and cooling airflow. Provide sufficient mounting foundation (frame 821) and consider reflected voltage effects from primary 240/480 V to avoid overheating. The unit’s compact footprint fits larger panels while meeting NEMA TP-1 guidelines.
Yes. It is UL Listed and NEMA TP-1 compliant, reflecting recognized safety and performance benchmarks for distribution transformers. The DOE 2016 Efficient rating further indicates that the NT20P11S7516CU is designed to minimize energy waste during idle and loaded conditions. These certifications support compliance reporting and provide procurement teams with confidence in long-term reliability.
The transformer delivers 75 kVA, with a primary voltage of 240/480 V and a secondary voltage of 120/240 V, designed for 60 Hz operation. This combination supports mid- to high-load distribution on industrial panels and control systems, with tap adjustments to tune voltage under varying loads. Copper windings and the sturdy frame 821 help sustain regulation under peak demand.
Ideal for industrial power distribution in machine control panels, automation racks, and critical control circuits. The single-phase design simplifies installation in compact panels and low- to mid-voltage distribution networks. Its K-Factor nonlinear characteristics help manage harmonics from motor drives, while electrostatic shielding reduces EMI impacting PLCs and sensors.
The unit ships with Eaton's policy: one year from installation or 18 months from shipment, whichever occurs first. Regular inspection of tap settings, connections, and cooling pathways helps sustain efficiency and prevent surprises. Energy savings arise from DOE 2016 Efficient design and tighter voltage regulation, reducing waste heat and extending instrument life, which lowers total cost of ownership over the equipment's service life.
