Hammond Power Solutions SK3A0225KK9K is a three-phase dry-type distribution transformer designed for stepping down primary voltage from a 480V delta configuration to a 480Y/277V wye secondary, providing both power and lighting loads with a grounded neutral. It delivers a 5.19 lb compact unit with a primary voltage rating of 480D and secondary voltage of 480Y/277, operating at 60 Hz with an enclosure rated Type 3R / IP24 for outdoor or indoor use. The transformer features a robust construction with copper windings and a core designed for low losses, housed in a weather-resistant enclosure that protects against rain, sleet, and external ice formation. It complies with CSA and UL certifications, ensuring adherence to North American safety and performance standards for industrial and commercial electrical distribution systems. Typical applications include power distribution in commercial buildings, industrial facilities, and outdoor installations where a 480V delta primary is converted to a 480Y/277V wye secondary for lighting, HVAC, and general power loads.
