What Is a Motor Control Center?

A motor control center is a centralized assembly that houses motor starters, protection devices, drives, and control equipment used to operate devices safely in industrial and commercial facilities, improving reliability, maintenance access, and coordinated motor control. Walk through any processing plant, pumping station, or large mechanical room, and you will eventually arrive at the same destination. A long lineup of enclosed sections, usually humming quietly behind closed doors, where most of the devices in the facility are started, protected, and controlled. That lineup is the motor control center, commonly called an MCC. Rather than scattering motor starters and protection devices…
