Limitamp MV MCC

The ABB 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, interlocking relays, programmable control, metering and other miscellaneous devices to be obtained in a single floor-mounted structural assembly fed from a common enclosed main bus.

Limitamp motor control centers are constructed of heavy gauge steel with each section housing horizontal and vertical bus with compartmentalized starters. Sections are bolted together to form a line-up of starters and equipment. The entire center may be powered by incoming line connections at a single point.

Typical applications are in paper, steel, cement, rubber, mining, petroleum, chemical, and utility-type industries. Limitamp control is also used in water and sewage plants and public buildings for air conditioning, pumps and compressors.
