This 45 kVA unit features a 480V delta primary connection and 480Y\/277V wye secondary configuration, operating at 60Hz frequency with a temperature rise of 150°C and 220°C insulation class. The transformer is housed in a Type 3R\/IP24 rated enclosure measuring 28.75\" H × 25.75\" W × 23.8\" D with ANSI 61 grey finish, featuring mechanical lug terminations and producing only 45 dBA sound levels. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic requirements (Sds=2.0, z\/h=1, lp=1.5). Typical applications include commercial buildings, industrial facilities, and utility power distribution systems requiring reliable voltage transformation with seismic resilience.      \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, 480Y\/277V Secondary\u003c\/li\u003e \u003cli\u003eCurrent: 45 kVA Capacity\u003c\/li\u003e \u003cli\u003eFrequency: 60Hz\u003c\/li\u003e \u003cli\u003eEnclosure: Type 3R\/IP24, ANSI 61 Grey\u003c\/li\u003e \u003cli\u003eTemperature Rise: 150°C\u003c\/li\u003e \u003cli\u003eInsulation Class: 220°C\u003c\/li\u003e \u003cli\u003eSound Level: 45 dBA\u003c\/li\u003e \u003cli\u003eImpedance: 2.5% -
