Motor Control Center
Motor Control Center (MCC), is an assembly of one or multiple enclosed sections that have a common power bus that primarily contains motor control units. A motor control center can potentially include Variable Frequency Drives (VFD), programmable controllers, and maybe the initial point where electricity will enter the facility.
Consists of one or more vertical metal cabinet sections with a power bus to allow for plug-in mounting of individual motor controllers. Each motor controller contains a solid-state motor controller, overload relays for protection, a circuit breaker, and a disconnection switch. The motor is wired to different terminals within the controller.
