Abstract:
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.

Claim (Index 8):
The DC overcurrent protection apparatus as claimed in  claim 1 , wherein the overcurrent detection unit incorporates a retaining element, which is arranged between a wall section of the overcurrent detection unit and a high-current-conducting bracket, which is moveable in relation to said wall section, wherein\n the bracket is retained by a retaining force of the retaining element in the direction of the wall section, and a permanent magnet is attached to the bracket and is carried in a winding such that, if no control voltage from a voltage source is present on the winding, a flow of current in the high-current path through the bracket is prevented, and the bracket does not constitute an element of the high-current path and, if the control voltage from the voltage source is present on the winding, and a current which is smaller than the predefined current is flowing in the high-current path, the bracket moves against the retaining force of the retaining element, such that the flow of current in the high-current path is routed through the bracket, and the bracket constitutes an element of the high-current path, in one direction of the current flow in the high-current path, a first control contact, up-circuit of the element of the high-current path constituted by the bracket, and a second control contact, down-circuit of the element of the high-current path constituted by the bracket, are respectively connected to the high-current path, between at least one of the first and second control contacts and the ignition current-controlled irreversible high-current switch-off element, a contactor, which is connected to the voltage source, is connected in-circuit such that, if no control voltage from the voltage source is present on the winding and on the contactor, and the bracket does not constitute an element of the high-current path, a no-load voltage which is present across the first and second control contacts does not result in the transmission of the ignition current to the ignition current-controlled irreversible high-current switch-off element, and the overcurrent detection unit is configured such that, if the overcurrent flows in the high-current path, the bracket, notwithstanding the control voltage from the voltage source which is present on the winding and on the contactor, moves away from that element of the high-current path which is not constituted by the bracket, in the direction of the retaining force of the retaining element, such that, on at least one high-current contact point between the bracket and the element of the high-current path which is not constituted by the bracket, an arc is generated, having a resistance, which results in a voltage drop across the first and second control contacts, wherein, in response to the voltage and the resistance, the ignition current is transmitted to the ignition current-controlled irreversible high-current switch-off element.
