A DC overcurrent protection apparatus includes an ignition current-controlled irreversible high-current switch-off element, an overcurrent detection unit which is electrically connected in a high-current path in series with the ignition current-controlled irreversible high-current switch-off element, and control contacts configured to control the ignition current-controlled irreversible high-current switch-off element. The control contacts are arranged such that they are electrically connectable to one another. The overcurrent detection unit is configured such that, when an overcurrent with a value equal to or greater than a predetermined current value flows in the high-current path, the control contacts, on account of an electromagnetic force generated by the overcurrent, are electrically connected to each other such that an ignition current is transmitted to the ignition current-controlled irreversible high-current switch-off element and the ignition current-controlled irreversible high-current switch-off element is switched by control to a switched-off state.
