This 300 kVA transformer features a 480V delta primary connection with multiple voltage taps and provides 208Y\/120V secondary output through wye-N configuration. Constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, the unit is housed in a Type 3R\/IP24 enclosure with ANSI 61 grey finish measuring 52\"H × 37.5\"W × 34\"D. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards while meeting IBC 2018 seismic requirements with Sds=2.0 and operating at 55 dBA sound levels. Typical applications include commercial buildings, manufacturing facilities, and industrial plants requiring reliable three-phase power conversion.      \u003cb\u003eKey Features \u0026amp; Specifications\u003c\/b\u003e  \u003cul\u003e \u003cli\u003eType: Three-Phase General Duty Transformer\u003c\/li\u003e \u003cli\u003eVoltage: 480V Delta Primary, 208Y\/120V Secondary\u003c\/li\u003e \u003cli\u003eCurrent: 300 kVA Capacity\u003c\/li\u003e \u003cli\u003eFrequency: 60Hz\u003c\/li\u003e \u003cli\u003eMaterial: Aluminum Windings\u003c\/li\u003e \u003cli\u003eTemperature Rise: 150°C\u003c\/li\u003e \u003cli\u003eInsulation Class: 220°C\u003c\/li\u003e \u003cli\u003eImpedance: 3.5% -
