Special features
K13
K-Factor nonlinear design with K13 and ventilated cooling addresses harmonic-rich loads. This design reduces harmonic distortion and manages heat more effectively, extending transformer life and minimizing unplanned downtime. Ideal for automation panels and manufacturing lines with nonlinear loads. DOE2016 Efficient compliance ensures lower no-load and load losses, translating to measurable energy savings and cooler operation across shifts. This is critical for plants aiming to reduce energy intensity and strengthen sustainability reporting. 150 kVA rating in a 3-phase, 480 V to 208Y/120 V configuration provides reliable power for PLCs, servo drives, sensors, and instrumentation. With this transformer, facilities can support scalable automation without oversizing equipment. Applications include manufacturing cells, data centers, and control rooms. Ventilated cooling supports higher ambient temperatures and a 115 °C rise, enabling higher continuous duty in hot environments. This reduces the risk of nuisance outages and extends service life. Ideal for hot shops, outdoor enclosures, and retrofit installations where cooling is constrained. UL Listed safety certification facilitates quick procurement and broad acceptance. Together with DOE2016 efficiency, it aligns with corporate compliance and energy programs. This simplifies installation in regulated facilities and reduces vendor risk. Robust physical specs support reliable installation with standard mounting footprints. Frame 943 and 305K wiring connections enable straightforward integration with Eaton and third-party distribution gear. At 31.5 in depth, 34.5 in width, and 51 in height, it fits in typical electrical rooms with proper clearances.
