This 1250 kVA unit features a 4160V delta primary and 480Y\/277V wye secondary configuration with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R\/IP24 enclosure with ANSI 61 grey finish, measuring 86 inches high by 78 inches wide by 52 inches deep, and operates at 65 dBA sound level with 4-7.5% impedance. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards (Sds=2.0, z\/h=0, lp=1.5). Typical applications include industrial plants, commercial facilities, and institutional buildings requiring reliable medium-voltage to low-voltage power conversion.      \u003cb\u003eKey Features \u0026amp; Specifications\u003c\/b\u003e  \u003cul\u003e \u003cli\u003eType: Three-Phase General Duty Transformer\u003c\/li\u003e \u003cli\u003eVoltage: 4160V Delta Primary \/ 480Y\/277V Secondary\u003c\/li\u003e \u003cli\u003eCurrent: 1250 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\u003eEnclosure: Type 3R\/IP24, ANSI 61 Grey\u003c\/li\u003e \u003cli\u003eDimensions: 86\"H × 78\"W × 52\"D\u003c\/li\u003e \u003cli\u003eSound Level: 65 dBA\u003c\/li\u003e \u003cli\u003eImpedance: 4-7.5%\u003c\/li\u003e \u003cli\u003eEfficiency Compliance: DOE 2016, NRCAN 2019, NMX 2021\u003c\/li\u003e \u003cli\u003eSeismic Rating: IBC 2018 (Sds=2.0)\u003c\/li\u003e \u003c\/ul\u003e \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: MG3A1250SKSAHC0\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Hammond Power Solutions\u003c\/li\u003e\n\u003cli\u003eBrand : Hammond Power Solutions\u003c\/li\u003e\n\u003cli\u003eCategory : Transformer\u003c\/li\u003e\n\u003cli\u003ePhase : 3\u003c\/li\u003e\n\u003cli\u003eEnclosure Grade : Standard\u003c\/li\u003e\n\u003cli\u003eDuty : General Duty\u003c\/li\u003e\n\u003cli\u003eFrequency : 60Hz\u003c\/li\u003e\n\u003cli\u003ePrimary Voltage : 4160D\u003c\/li\u003e\n\u003cli\u003ePrimary Connection : Delta\u003c\/li\u003e\n\u003cli\u003ePrimary FCAN (NPL) : 2x2.5%\u003c\/li\u003e\n\u003cli\u003ePrimary FCBN (NPL) : 2x2.5%\u003c\/li\u003e\n\u003cli\u003eSecondary Voltage : 480Y\/277\u003c\/li\u003e\n\u003cli\u003eSecondary Connection : Wye-N\u003c\/li\u003e\n\u003cli\u003eMaterial : Aluminum\u003c\/li\u003e\n\u003cli\u003eTemperature Rise : 150°C\u003c\/li\u003e\n\u003cli\u003eInsulation Class : 220°C\u003c\/li\u003e\n\u003cli\u003eEKVA : 1250\u003c\/li\u003e\n\u003cli\u003eEfficiency Regulation : DOE 2016 (US), NRCAN 2019 (Canada), NMX 2021 (Mexico)\u003c\/li\u003e\n\u003cli\u003eSeismic Compliance : IBC 2018 (Sds=2.0, z\/h=0, lp=1.5)\u003c\/li\u003e\n\u003cli\u003eSound Level : 65 dBA (IEEE C57.12.01)\u003c\/li\u003e\n\u003cli\u003eImpedance (Std) : 4% -
