The document discusses MCC (motor control center) panels and smart MCC panels. It notes that MCC panels contain motor control units and feeders for motors, can operate automatically or manually, and have a steel structure with internal wiring. Smart MCC panels can be operated remotely, link digital controllers to analog actuators, and monitor motor operation, energy consumption, and system functioning through communication with PLCs over a data network. The advantages of smart MCC panels include lower installation, maintenance, and energy costs as well as increased efficiency and system information.
