Overview

The Hammond Power SG3A0045KB0C is a 600V class, three-phase, dry-type distribution transformer engineered for energy efficiency in commercial and industrial power distribution systems. This 45 kVA unit converts 480V delta primary voltage to 208Y/120V wye secondary voltage, making it ideal for powering balanced three-phase loads such as lighting systems, HVAC equipment, and industrial machinery. Core to its performance is the use of premium copper windings, which minimize internal energy losses and enhance operational efficiency. The transformer meets DOE2016 and NRCan 2019 energy efficiency standards, ensuring reduced energy consumption and lower operational costs. Its secondary winding is configured in a wye (Y) connection, delivering stable and consistent voltage output for compatibility with modern electrical distribution networks. Operating at 60 Hz, the SG3A0045KB0C is designed for seamless integration with North American power grids. The compact footprint allows efficient use of space in electrical rooms or indoor environments, while its robust construction ensures reliable performance under fluctuating load conditions. This transformer is a cost-effective solution for facilities prioritizing energy efficiency and long-term reliability in power distribution.
