Since 1948, ABB has driven the development of Motor Control Centers, from the first plug-in combination starter to the first fully segregated units to contain fault damage. Evolution's 850A Vertical Bus, Snap-In Shelves, Plug-In Feeders to 600A, and Plug-In Starters to Size 5 provide customers with more flexibility to move buckets around and ad them in the future.

The Limitamp motor control center provides an economical means of centralizing motor starters and related control equipment. It permits motor control starters, feeders, isolator switches, distribution transformers, and more devices to be obtained in a single floor-mounted structural assembly fed from a common enclosed main bus.
