Eaton Specification Sheet - N29M47T75CUEELS47
Feature → Business Impact → Application: The N29M47T75CUEELS47 employs a nonlinear K-Factor ventilated design that enhances thermal performance, reducing hotspots and extending insulation life, which translates to fewer unplanned outages in continuous-process environments such as metal fabrication or chemical processing. In practice, this means improved uptime and lower maintenance costs for 75 kVA, three-phase loads running on 208 V primaries with 480Y/277 V secondaries. Feature → Business Impact → Application: Copper windings maximize conductivity and durability, delivering consistent voltage regulation under dynamic load swings, ideal for sensitive drive systems and PLC racks in manufacturing lines. Feature → Business Impact → Application: Tap settings of 2 at +2.5% and 4 at -2.5% provide voltage flexibility to accommodate minor supply fluctuations without swapping transformers, simplifying installation in multi-branch power distribution islands. Feature → Business Impact → Application: NEMA TP-1 low-sound design, electrostatically shielded construction, and WS19 weather protection reduce noise and environmental ingress, enabling siting near work areas or outdoors in challenging plants while maintaining compliance with workplace noise limits. Feature → Business Impact → Application: 150 °C rise capability with a 200 °C insulation system supports reliable operation in hotter plant rooms and during startup surges, decreasing the risk of performance degradation on heavy loads. Feature → Business Impact → Application: 75 kVA rating with 60 Hz operation and three-phase configuration ensures compatibility with mid-range industrial feeders, facilitating consolidation of power stages and reducing project footprint and wiring complexity.

FAQs
For installation, ensure proper enclosure or room with adequate clearance around the transformer to allow airflow for the ventilated design. Verify mounting orientation and vibration isolation, confirm 208 V primary and 480Y/277 V secondary connections are wired to the correct bus sections, and account for the 75 kVA rating in the downstream protection and breaker sizing. Use copper windings and maintain adequate access for taps and maintenance.
Key specs include three-phase operation at 60 Hz, a 75 kVA VA rating, primary voltage of 208 V, secondary voltage of 480Y/277 V, and a temperature rise of 150 °C with a 200 °C insulation system. Taps are 2 at +2.5% and 4 at -2.5%, copper windings, and a frame 916A. It features NEMA TP-1 low-sound design and electrostatic shielding, with WS19 weather protection.
Yes. The N29M47T75CUEELS47 is designed for flexible siting with low sound output (NEMA TP-1 equivalent) and WS19 weather protection. Its electrostatically shielded copper windings reduce stray fields, helping to meet ergonomic and safety requirements in plant rooms or exterior equipment areas where noise and environmental ingress are concerns.
Ideal for mid-range industrial power distribution, this 75 kVA three-phase transformer supports equipment startup and continuous operation for manufacturing lines, process control, and drive systems. The +/– tap settings help accommodate voltage fluctuations, while the copper windings and insulation system improve reliability, enabling fewer interruptions and lower maintenance costs in facilities like metalworking, plastics, and packaging.
