3MVA Transformer 13800V / 480Y277
$251,360
With a transformer rating of 3 MVA (3000 KVA), the industrial transformer features a dual rated primary voltage of three-phase 13800V Delta and a secondary voltage of three-phase 480Y/277 V Wye. An input voltage switch allows the transformer to be switched between primary voltages. The unit has a primary loop feed for single installations and dead-front primary connections. This transformer features a 5-position tap changer with two, +/- 2.5% taps above and two, +/- 2.5% taps below to allow small changes for voltage.
