Mini Power Center

Product Overview & Application


Mini Power Centers combine three individual components, prewired into one NEMA 3R enclosure: a primary main breaker, a single-phase or three-phase dry-type encapsulated transformer (Type EP), and a secondary distribution load center with main breaker. Inter-connecting wiring is completed at the factory. Mini Power Centers are used wherever there is a 480V or 600V distribution system and loads requiring 208Y/120V, three-phase or 120/240V single-phase.
