The K-Factor 13 nonlinear capability, aluminum windings, and an electrostatic shield target harmonic suppression while minimizing copper losses. This feature improves temperature performance and reliability under nonlinear loads common in modern facilities. It’s well suited for three-phase power paths in manufacturing, data centers, and heavy industry where harmonic distortion can impact downstream equipment. DOE 2016 efficiency compliance, UL Listed status, and 10 CFR Part 431 notes frame a robust regulatory package. These certifications deliver regulatory alignment, predictable performance, and reduced lifecycle costs. Rugged NEMA 2 enclosure protects against dust and moisture, with WS60 weather-shield option for additional protection in challenged environments. Tap changer options of 2 at +2.5% and 4 at -2.5% provide voltage regulation. Precise regulation reduces voltage swings, minimizing nuisance trips and protecting sensitive equipment. Applicable to 208 V primary to 208Y/120 V secondary configurations in commercial and industrial networks. Floor-or-wall upright mounting, FR943 frame, 220 °C insulation, 986 lb weight, and NEMA 2 enclosure. Durable construction and a practical footprint simplify installation and service access in busy facilities. Indoor factory floors, equipment rooms, and mission-critical panels requiring robust protection are well served. 75 kVA three-phase rating at 60 Hz with primary 208 V and secondary 208Y/120 V. Provides ample headroom for peak loads, enabling scalable distribution and fewer outages. Suitable for mid-size data centers, manufacturing lines, and power distribution cabinets.

FAQs
Plan for a floor- or wall-mounted installation with upright orientation on a FR943 frame. The unit weighs 986 lb and measures 31.5 in deep by 34.5 in wide and 51 in tall, so provide reinforced mounting points and adequate clearance for access. Use the 283A wiring connection per the nameplate, and ensure ventilated space to accommodate the 115°C rise rating while maintaining compliance with NEMA 2 enclosure requirements.
K-Factor 13 indicates enhanced tolerance to non-linear loads, reducing derating and improving overall efficiency under harmonic-rich conditions. This reduces copper losses and thermal stress, increasing transformer life. In practice, you’ll see steadier voltage delivery to sensitive loads and lower energy waste in facilities with variable-speed drives, rectifiers, and other nonlinear equipment.
Yes. The transformer features a 208 V primary and 208Y/120 V secondary, three-phase configuration, and 60 Hz operation, making it compatible with common data center and IT room power distribution schemes. Its aluminum windings and shielded construction further support reliability, while UL Listed and DOE 2016 efficiency align with data center regulatory and energy standards.
Verify UL Listed status for electrical safety, DOE 2016 efficiency compliance for energy performance, and 10 CFR Part 431 alignment for appliance efficiency standards. The N29M28F7516 also notes DOE 2016 Efficient cataloging and a NEMA 2 enclosure, with electrostatic shield and WS60 weather-shield option as applicable to your installation environment.
Expect favorable total cost of ownership due to high efficiency (DOE 2016), solid protection (UL Listed, NEMA 2, shield, WS60), and a robust 75 kVA rating that reduces the need for oversizing. Maintenance considerations include regular visual inspections, insulation checks (115°C rise rating), and verifying taps at +2.5% and -2.5% to maintain voltage accuracy. The rugged FR943 frame supports long service life in demanding industrial environments.
