Motor Control Circuit Components. Motor control centers mcc in many commercial and industrial applications quite a few electric motors are required and it is often desirable to control some or all of the motors from a central location. In order for the motor to operate the 3 phase disconnect must be closed the fuses must be in good working order and the power contacts must be closed.
Controller typically a microcontroller or dsp. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter which in turn consists of motor starter fuses or circuit breaker and power disconnect. Motor control circuits are often con nected to lower voltages than the motor they control to make it safer for operators and maintenance personnel.

Two wire control circuits and three wire control circuits. In practical applications these four components would often be mounted in a combination starter which might house a circuit breaker and motor starter in the same cabinet. There are two modes through which motor control components can start or stop the motor either manual or automatic. A manual circuit breaker opens and closes a circuit like a toggle switch.
