A power distribution unit includes a housing, a main contactor in a main cavity of the housing, and a pre-charge assembly in a secondary cavity of the housing. The main contactor includes first and second fixed contacts and a movable contact configured to electrically connect the first and second fixed contacts in a mated position. The main contactor includes a coil assembly energized to move the movable contact. The pre-charge assembly includes a pre-charge resistor and a pre-charge switch coupled to the pre-charge resistor. The power distribution unit includes a controller received in the housing. The controller includes a main contactor driver for powering the main contactor and a pre-charge driver for powering the pre-charge switch.
