Zusammenfassung:A motor starter apparatus includes an enclosure, a bypass contactor configured to be installed in the enclosure and configured to selectively couple a power source to a motor, and a reduced voltage soft starter (RVSS) circuit assembly (e.g. a wheeled truck) configured to be installed in the enclosure, to be coupled to the power source and to apply a variable voltage to the motor. The bypass contactor is configured to preserve a connection of the bypass contactor to the power source and the motor when the RVSS circuit assembly is removed from the enclosure.
