Hammond Power Solutions SK3A0225KK3S is a three-phase energy-efficient k-factor distribution transformer designed to mitigate harmonic heating from non-linear loads in industrial power systems. It operates with a primary voltage of 480V Delta and a secondary voltage of 480Y/277V, delivering 225kVA of capacity at 60 Hz with a 150°C temperature rise. The unit features aluminum windings and is housed in a heavy-duty NEMA 3R ventilated enclosure with an ANSI 61 grey finish, weighing 1650 lb. It is CSA and UL certified, meeting DOE 2016 efficiency standards under 10 CFR Part 431, with a BIL rating of 10 kV. This transformer is typically applied in commercial and industrial settings where non-linear loads such as variable frequency drives and UPS systems are present.
