FAQs
This transformer suits industrial substations and equipment rooms with three-phase power, offering a 480 V primary and 208Y/120 V secondary. Its footprint (31.5 in L × 34.5 in W × 51 in H) and weight (approximately 1,200 lb) are compatible with standard mounting rails and room layouts, while the 283B wiring connection simplifies conduit planning and integration with existing switchgear.
Key specs include a 150 kVA rating, three-phase configuration, primary voltage of 480 V, and secondary voltage of 208Y/120 V, with a 150 °C rise. It also features a K-Factor nonlinear design (K13) and a noise level around 49 dB, all supported by DOE2016 Efficient performance and UL Listed certification for safety and efficiency.
Yes. The K-Factor nonlinear design is specifically intended to manage harmonic currents, maintaining voltage stability and protecting sensitive equipment. The K13 feature further enhances resilience to harmonic distortion, making it well-suited for drives and other nonlinear loads common in modern manufacturing and automation environments.
This unit carries UL Listed certification and complies with DOE2016 Efficient standards, providing safety assurances and energy efficiency. These credentials help meet corporate sustainability goals, reduce lifecycle costs, and simplify approvals for facilities subject to electrical safety and energy-use regulations.
The DOE2016 Efficient design lowers standby and running losses, reducing energy bills over the life of the transformer. Regular maintenance should focus on wiring integrity (283B connection), cooling system checks for the ventilated frame, and periodic inspections of thermal rise performance to sustain reliability and extend service life in high-demand environments.
