MG3A0015SBSCHC0 - Hammond Power Solutions 15kVA 3 Phase 4160D-480Y/277V Aluminum Medium Voltage Distribution Transformer NEMA 3R

MG3A0015SBSCHC0

MG3A0015SBSCHC0 is a three-phase medium voltage distribution transformer designed for commercial and industrial applications requiring reliable voltage step-down from 4160V delta to 480Y/277V. This unit is part of the HPS Millennium G series, engineered for high efficiency and durability in demanding environments. The MG3A0015SBSCHC0 features an aluminum winding construction and is built to meet the latest U.S. DOE 10 CFR Part 431 efficiency standards. The transformer is housed in a NEMA 3R enclosure, suitable for both indoor and outdoor installations. It is designed for 60 Hz operation and offers a temperature rise of 130°C with a 200°C insulation class. The primary connection is delta, and the secondary provides a wye configuration with a vector group of Dyn1 (-30°). The unit is typically floor-mounted and comes with mechanical lugs for primary termination.
