Motor control centers are a modern method in factory assembly for some motor starters. This particular equipment can 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 often are used for low voltage, 3-phase alternating current motors which range from 230 V to 600V. Medium voltage motor control centers are designed for big motors which vary from 2300 volts to 15000 volts. These units use vacuum contractors for switching with separate compartments to be able to attain power switching and control.

In order to complete testing or maintenance, really big controllers can be bolted into place, whereas smaller controllers can be unplugged from the cabinet. Each motor controller has a solid state motor controller or a contractor, overload relays to protect the motor, fuses or circuit breakers to supply short-circuit protection and a disconnecting switch to be able to isolate the motor circuit. Separate connectors allow 3-phase power so as to enter the controller. The motor is wired to terminals positioned inside the controller. Motor control centers offer wire ways for power cables and field control.

Inside a motor control center, every motor controller can be specified with lots of various alternatives. Some of the options consist of: extra control terminal blocks, control switches, pilot lamps, separate control transformers, and numerous kinds of solid-state and bi-metal overload protection relays. They also comprise various classes of kinds of power fuses and circuit breakers.

There are a lot of options regarding delivery of MCC's to the client. They can be delivered as an engineered assembly with interlocking wiring to a central control terminal panel board or programmable controller together with internal control. Conversely, they could be supplied ready for the customer to connect all field wiring.

MCC's commonly sit on floors that must have a fire-resistance rating. Fire stops may be required for cables which penetrate fire-rated floors and walls.
