Motor control centers are a modern technique in factory assembly for several motor starters. This machinery could comprise variable frequency drives, programmable controllers and metering. The MCC's are normally found in the electrical service entrance for a building. Motor control centers frequently are used for low voltage, 3-phase alternating current motors which vary from 230 volts to 600 volts. Medium voltage motor control centers are made for large motors which range from 2300V to 15000 V. These units use vacuum contractors for switching with separate compartments in order to accomplish power switching and control.
In places where really corrosive or dusty processes are happening, the motor control center may be established in a separate air-conditioned room. Usually the MCC would be situated on the factory floor near the machines it is controlling.
A MCC has one or more vertical metal cabinet sections with power bus and provisions for plug-in mounting of individual motor controllers. Smaller controllers can be unplugged from the cabinet in order to complete maintenance or testing, while extremely big controllers can be bolted in place. Each motor controller consists of a solid state motor controller or a contractor, overload relays In order to protect the motor, fuses or circuit breakers to supply short-circuit protection and a disconnecting switch in order to isolate the motor circuit. Separate connectors enable 3-phase power to enter the controller. The motor is wired to terminals positioned within the controller. Motor control centers supply wire ways for power cables and field control.
Inside a motor control center, each motor controller can be specified with several various options. Some of the choices include: extra control terminal blocks, control switches, pilot lamps, separate control transformers, and various types of bi-metal and solid-state overload protection relays. They also have different classes of types of circuit breakers and power fuses.
