The Motor Control Center (MCC) plays a crucial role in modern industrial and commercial setups by acting as the primary source of power distribution to various sections of the plant or building. It typically receives power from the PCC (Power Control Center) panel and then distributes it efficiently and safely. The MCC setup generally consists of a combination of Air Circuit Breakers (ACBs), Molded Case Circuit Breakers (MCCBs), Motor Protection Circuit Breakers (MPCBs), protection relays, and measuring devices — all chosen based on the specific requirements of the industry and application.

To enhance operational safety, the integration of a Lock-Out Tag-Out (LOTO) system ensures that machinery and electrical panels are properly shut down and isolated before maintenance, protecting both the equipment and personnel from unexpected energization.
