The Weg star-delta bus bars for CWB contactors provide an easy means of building a star-delta motor starter for 3-phase electric motors. These re specialized starters used to reduce the start-up in-rush currents on electric motors. A star-delta starter consists of 3 contactors working together to provide the appropriate switching so that the motor starts in a lower-current 'Y' mode, and then switches to 'Delta' mode once full speed is reached.
Star-Delta starters should not be used when the motor is controlled by a soft-start or VFD drive.
