A motor control center (mcc) is an assembly of 1 or maybe more enclosed sections having a power that is common and principally containing motor control units. Motor control centers are in modern practice a factory assembly of several engine starters. A motor control center can include frequency that is variable, programmable controllers, and metering and may even also function as the electrical service entry for the building. Motor control centers usually are employed for low voltage three-phase alternating current motors from 208 v to 600 v. Medium-voltage engine control centers are designed for large motors running at 2300 v to around 15000 v, making use of vacuum cleaner contactors for switching and with separate compartments for power switching and control-electric motor & pumps .
