Claim 21:
22. A control system for controlling an interrupter, the interrupter being configured to be started by a startup current to interrupt a main electric circuit, the startup current flowing through an auxiliary electric circuit and having a current valve equal to or greater than a predetermined value, the control system comprising:
a driving unit including an intermediate electrical path to be connected to the main electric circuit; and
a driven unit to be connected to the auxiliary electric circuit,
wherein the driving unit is configured to, when an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, use, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path,
the driven unit is configured to supply the auxiliary electric circuit with the startup current by being driven by the driving unit,
the interrupter includes:
a moving contactor constituting the intermediate electrical path of the driving unit;
a fixed terminal configured to come into contact with the moving contactor;
a holder configured to give the moving contactor holding force for keeping the moving contactor in contact with the fixed terminal;
an auxiliary moving contact configured to move as the moving contactor moves; and
an auxiliary fixed contact facing the auxiliary moving contact, and

the moving contactor is configured to move from a first position to a second position by overcoming the holding force with electromagnetic repulsion caused by the abnormal current flowing through the moving contactor as the intermediate electrical path, one position selected from the group consisting of the first position and the second position being a position where the auxiliary moving contact is out of contact with the auxiliary fixed contact, the other position selected from the group consisting of the first position and the second position being a position where the auxiliary moving contact is in contact with the auxiliary fixed contact.
