Abstract
A power distribution unit includes a housing having walls defining a main cavity provided at a first side and a secondary cavity provided at a second side. The power distribution unit includes a main contactor received in the main cavity having first and second fixed contacts and a movable contact movable between a mated position and an unmated position to electrically connect the first and second fixed contacts. The main contactor includes a coil assembly energized to move the movable contact. The power distribution unit includes a pre-charge assembly received in the secondary cavity having a control circuit board, a pre-charge resistor coupled to the control circuit board, and a pre-charge switch coupled to the control circuit board. The power distribution unit includes a cover coupled to the housing to enclose the pre-charge assembly in the secondary cavity.
