Beschreibung
Zusammenfassung:	A system including a vehicle having a motive electrical power path; a power distribution unit having a current protection circuit disposed in the motive electrical power path, the current protection circuit including: a first leg of the current protection circuit comprising a first pyro-fuse; a second leg of the current protection circuit comprising a thermal fuse in series arrangement with a second pyro-fuse; and where the first leg and the second leg are coupled in a parallel arrangement; a controller, including: a current detection circuit structured to determine a current flow through the motive electrical power path; and a pyro-fuse activation circuit structured to provide a pyro-fuse activation command in response to the current flow exceeding a threshold current flow value; and where at least one of the first pyro-fuse and the second pyro-fuse is responsive to the pyro-fuse activation command.
