Low and Medium voltage Motor Control
A motor control center (MCC) is an assembly of one or more
enclosed sections having a common power
bus and principally containing motor control units. Motor control center
can include variable frequency drives, programmable controllers, and metering.
equipment can be fabricated for low voltage
three phase alternating current motors
from 208 V to 600 V. Medium-voltage motor control centers are for large motors running
at 2300 V to around 15000
V, using vacuum contactors for switching
and with separate
compartments for power switching and control.
