The protection circuit unit includes an energization module disposed on an electric path between a high-voltage battery of a vehicle and a high-voltage load receiving supply of power from the high-voltage battery, to open and close the electric path, and a control board configured to be a member separated from the energization module and electrically connected with the energization module, to control opening and closing of the electric path. The energization module includes semiconductor switches opening and closing the electric path, and a control terminal connecting the semiconductor switches with the control board. The control board includes a connection unit corresponding to the control terminal of each of a plurality of types of the energization modules.
