Hammond Power Solutions SK3A0030KK4S is a three-phase dry-type distribution transformer designed for stepping down primary voltage to a secondary wye configuration for industrial power distribution. It operates with a primary voltage of 480V delta (480D) and a secondary voltage of 480Y/277V, providing a 277V phase-to-neutral output for lighting and equipment loads. The unit weighs 280 lb and is housed in a Type 3R / IP24 enclosure, constructed for outdoor or indoor use with protection against rain and sleet. It is certified to CSA and UL standards, ensuring compliance with North American electrical safety requirements. Typical applications include commercial and industrial facilities requiring a 480V delta primary to 480Y/277V secondary transformation for panelboards, motor control centers, and lighting systems.
