FAQs
Plan for a three-phase installation with proper ventilation and adequate space for airflow around the transformer. Ensure the location supports the 80°C rise rating and that the secondary circuits are wired to 208Y/120 V panels or MCCs. Use the ±2.5% taps to tighten voltage under load and verify clearances per local electrical codes during rack or cabinet mounting.
The unit is a 300 kVA, three-phase transformer with a 480 V primary and a 208Y/120 V secondary. It features KT-13 K-Factor nonlinear design, vented cooling, and taps at +2.5% and -2.5% (two each). Operating temperature rise is up to 80°C, making it suitable for medium-load industrial environments.
Yes. Its nonlinear K-Factor design helps mitigate harmonics, improving power quality for sensitive IT equipment and control systems. The 480 V to 208Y/120 V transformation supports data-center auxiliary circuits and factory automation panels, while the taps enable voltage regulation under varying loads common in manufacturing lines.
Certification specifics are provided by the manufacturer and can vary by region. Typical documentation may include CE or UL listings and regional compliance proofs.
