Eaton's Unitized power centers are self-contained metal-enclosed unit substations specially designed to supply and distribute low voltage power from medium-voltage lines in modern commercial and industrial systems. Unitized power centers are easily and conveniently applied throughout a distribution system at physical locations close to centers of load concentration, and distribution voltage is stepped down to the utilization voltage only at or near the areas of demand. They are ideal where considerations of equipment size, accessibility, maintainability, ease of installation, and overall economy are of utmost importance.
