FAQs
Plan floor mounting for a heavy unit (2628 lb) with a floor-anchored base; ensure 66.18 in height and 42.18 in width fit the service bay. Provide clearances for wiring access (283B connection) and allow service space for cooling, maintenance, and shield installation.
K-Factor 13 with nonlinear windings reduces stray and copper losses under non-linear loads. The ventilated design improves cooling, enabling sustained efficiency and load handling in facilities with harmonics from drives and switching electronics.
Yes. It is a three-phase transformer with primary 480 V and secondary 480Y/277 V, rated at 225 kVA, designed for 60 Hz operation, suitable for distributing 480 V to 480Y/277 V circuits in industrial environments.
UL Listed certification and DOE 2016 efficiency (10 CFR Part 431) compliance are provided. You also get a NEMA 2 enclosure, electrostatic shield option, and WS62 weathershield compatibility for protection in various indoor environments.
Energy efficiency reduces operating costs, the electrostatic shield minimizes EMI and stray losses, and copper windings with high insulation margin extend service life. Over time, these factors translate to lower maintenance costs and a faster return on investment.
