MCC panel

A Motor Control Centre (MCC) panel is a centralised electrical assembly used to control and protect multiple electric motors from a single location. It houses motor starters, protective relays, and control devices in individual compartments, allowing operators to start, stop, and monitor motors efficiently. MCC panels are widely used in industrial plants and large facilities where several motors need to be managed in a coordinated and safe manner.
