The K-Factor nonlinear ventilation design improves thermal performance under harmonic loads. This reduces insulation stress, lowers the risk of unplanned outages, and cuts lifecycle costs in high-harmonic environments while delivering reliable three-phase distribution for data centers, manufacturing lines, and large industrial facilities. The ventilated construction with WS19 weather shield enables outdoor or harsh environment installation, enhancing cooling efficiency and extending service intervals for outdoor substations and exposed equipment.Aluminum windings reduce material costs and weight while supporting a 150°C rise, enabling easier handling and robust performance in factory or distribution center applications. This combination delivers a cost-effective balance of durability and efficiency in mid-size power networks, with a focus on fast commissioning and long-term operation in dynamic loads. Tap settings provide ±5% voltage adjustment (1 at +5% FCAN, 2 at -5% FCBN), delivering precise regulation to maintain 208 V primary and 208Y/120 V secondary under fluctuating supply conditions. This reduces downtime and improves equipment uptime across rotating loads and intermittent demand scenarios.UL Listed certification confirms safety compliance and aligns with procurement and maintenance standards for industrial power systems. The 112.5 kVA three-phase transformer, frame 916A, and 60 Hz rating are matched to standard electrical rooms and service feeds, enabling straightforward integration with existing switchgear and bus systems. The robust enclosure and electrostatic shield further support reliability in harsh environments, while the WS19 weathershield protects against weathering and contaminants, extending service life and reducing inspection frequency.

FAQs
The N29R28T12 uses a 916A frame and is designed for robust mounting in standard electrical rooms or outdoor enclosures. With aluminum windings and electrostatic shielding, its vented construction supports effective cooling. WS19 weather shield enables outdoor or harsh environment installations, while the unit’s dimensions (length/depth 23.42 in, height 48.56 in, width 28.22 in) and weight of 909 lb influence supporting structures and crane/rigging needs. Ensure proper ventilation and clearance for service access.
The K-Factor nonlinear design is tailored to manage harmonic currents more effectively than linear transformers, reducing overheating and insulating stress under non-sinusoidal loads. This translates to improved reliability, longer insulation life, and lower maintenance interventions in facilities with harmonic-rich equipment such as drives and non-linear power supplies. It also supports safer operation within standard data center and manufacturing environments.
Yes. With a 112.5 kVA rating, 208 V primary, and 208Y/120 V secondary, this three-phase transformer is well-suited for data centers and industrial facilities requiring stable voltage and dependable fault tolerance. The ventilated design, aluminum windings, and WS19 weather shield offer efficient cooling and environmental protection, while taps provide ±5% voltage adjustment to compensate for supply fluctuations.
The N29R28T12 is UL Listed, indicating compliance with recognized electrical safety standards. This helps simplify parts approval, reduces risk in regulated environments, and aligns with typical procurement requirements for industrial power systems. Coupled with a warranty policy from Eaton, buyers gain assurance of post-sale support and service coverage for ongoing reliability.
Eaton provides a warranty under policy 25-000 offering one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, expect routine inspections around the WS19 shield and ventilated enclosure, with attention to tap position accuracy and cooling performance. The aluminum windings and robust frame reduce long-term maintenance costs and downtime in busy facilities.
