Claim:
1. An electrical machine having an at least one multiple-phase stator winding connected to a power converter in a multiple-phase circuit by a group of cables each carrying a respective phase of the multiple-phase circuit, the machine comprising: an electrical protection circuit including a switching device including a group of contacts connected between the electrical machine and the power converter via a first connection; a controller communicatively connected to the power converter and to the electrical protection circuit, wherein the controller is configured to sense fault current and configured to activate the electrical protection circuit; and a common conductor connected to the group of contacts of the electrical assembly via a second connection opposite the first connection, wherein each cable of the group of cables is connected in parallel to the common conductor by a separate contact of the group of contacts, and when a fault occurs, the group of contacts is closed to connect each cable of the group of cables to the common conductor and to short-circuit a total of the respective phases of the multiple-phase circuit.
