Motor control relays: Workhorses of the control world

Motor control relays are heavy-duty relays used to control motor starters and other industrial components. More specifically, they are typically used to energize the coil of a motor starter or contactor, which in turn starts a motor. A motor protective relay is a type of motor control relay used to prevent the coil of a motor starter or contactor from being energized.
