K-Factor nonlinear ventilated design improves thermal management and harmonic response, reducing hot spots and extending transformer life while enabling more stable operation in high-demand facilities. Business impact: lower cooling energy, fewer maintenance cycles, and improved uptime in data centers, shops, and process plants. Application: suitable for systems with harmonic loads and limited ducting, such as automation panels and header substations. 75 kVA three-phase rating provides ample headroom for common industrial feeders without oversizing equipment. Business impact: optimized asset utilization, reduced capital expenditure, and easier panel integration. Application: machine tool lines, HVAC drives, and pump stations in manufacturing environments. Designed for 480-208Y/120V service with a vented XFMR body, installation is straightforward in standard electrical rooms and enclosures. Business impact: faster deployment, consistent electrical clearances, and easier commissioning. Application: new builds and retrofit projects where space is constrained and ventilation is critical. UL Listed certification supports safety compliance for industrial facilities and utilities, while the K13 specification guides harmonic mitigation strategies. Business impact: risk reduction, audit readiness, and smoother code compliance. Application: mission-critical substations, data centers, and regulated manufacturing. Compact footprint and Eaton documentation compatibility simplify procurement and maintenance planning, lowering total cost of ownership over the transformer’s lifecycle. Business impact: predictable maintenance windows, standardized parts, and reliable spare-part availability. Application: multi-site deployments and OEM integration across automation and power distribution networks.

FAQs
Plan for a three-phase 480-208Y/120V service with adequate ventilation around the vented XFMR. Check mounting clearance, ensure access to the cataloged dimensions (approximately 21.13 in L, 36.88 in H, 24.88 in W), and verify UL Listed compliance in your facility. Use proper enclosure ratings and follow Eaton installation guidelines to minimize thermal build-up and noise.
The N48M28T7521CSCU delivers 75 kVA with a three-phase configuration and a voltage rating of 480-208Y/120V. This combination supports standard industrial feeders and enables reliable downstream equipment operation while addressing harmonic and thermal considerations through its K13 design.
Yes. Its K-Factor nonlinear design and vented construction are well-suited for spaces with harmonic loads, common in data centers and manufacturing environments. The UL Listed certification supports safety and code compliance, while the 75 kVA rating matches many common power distribution scenarios without over- or under-sizing.
The transformer is UL Listed, which validates safety and compatibility with established electrical codes. This certification reduces audit risk, simplifies procurement in regulated facilities, and supports reliability expectations for industrial power distribution equipment. No CE or IP data is provided in the current specification, so verify regional requirements with Eaton for your location.
Benefits include lower cooling energy due to better thermal management, reduced maintenance cycles from a robust vented design, and improved uptime through reliable three-phase power delivery. The combination of a medium kVA rating with a compact footprint also lowers capital expenditure and accelerates project timelines in multi-site deployments.
