Feature → Business Impact → Application The K-Factor nonlinear design manages harmonic currents more effectively, improving system efficiency and reducing overheating in nonlinear loads, which translates to longer component life and fewer unplanned outages in manufacturing lines. Application: best for facilities with switched-mode power supplies or drives that introduce harmonic content. The ventilated cooling design with a 912B frame provides superior heat dissipation, enabling higher ambient operation and extending service intervals in compact switchgear or equipment rooms. Application: data centers and assembly lines where space is at a premium. Tap settings, two taps at +2.5% and four taps at -2.5%, enable precise voltage regulation to compensate line drops and voltage sag, reducing secondary-side voltage variance and protecting sensitive equipment. Application: sites with fluctuating utility voltage or long feeder runs. The 30 kVA three-phase core, copper windings, and electrostatic shield offer robust short-circuit performance and EMI containment, improving protection for downstream controllers and motors. Application: critical drives, PLCs, and motor control centers. The WS38 weathershield option and frame 912B enhance outdoor or harsh indoor environments, enabling safer outdoor installations or harsh factory spaces with minimal enclosure changes. Application: outdoor substations and industrial spaces near large equipment clusters. The low-noise 42 dB catalog note supports quiet operation in offices, labs, or control rooms adjacent to transformer installations, helping maintain a productive work environment. Application: noise-sensitive commissioning and maintenance areas. With UL Listed certification and a 1-year warranty (or 18 months from shipment, per Eaton policy), users gain confidence in safety, serviceability, and vendor support, which translates to lower life-cycle risk and easier procurement. Application: regulated facilities and procurement teams prioritizing certified, traceable equipment.

FAQs
This transformer is a three-phase unit rated for 480 V primary and 208Y/120 V secondary, designed for standard industrial distribution panels. It uses a 912B frame and copper windings with an electrostatic shield, making it compatible with common enclosure sizes and control systems. Ensure adequate ventilation, space for cooling clearances, and proper tap selection (+2.5% or -2.5%) to maintain voltage stability at the load site.
Key specs include 30 kVA rating, 60 Hz operation, 115°C temperature rise, and copper windings with electrostatic shield. The unit is K-Factor nonlinear and ventilated, which helps manage harmonics and heat. Confirm UL Listed certification, sound level around 42 dB, and the WS38 weather shield option for outdoor or harsh indoor environments.
Yes. With a 208Y/120 V secondary, stable voltage regulation, and superior EMI containment from the shield, this transformer reduces voltage fluctuations that can affect servers, analyzers, and instrumentation. The low noise profile and UL safety certification further support use in quiet, safety-conscious environments.
The product is UL Listed, indicating conformance to recognized safety standards for electrical equipment. While CE or IP ratings are not specified in the provided data, UL Listed status provides essential compliance for many industrial installations. Always verify site-specific regulatory requirements before procurement.
Eaton offers a warranty policy of one year from the date of installation or eighteen months from shipment, whichever comes first. Regular maintenance should include inspection of windings for signs of overheating, verification of tap settings for voltage accuracy, and periodic thermal checks to ensure the 115°C rise rating remains within design limits.
