Abstract: A pyrotechnic circuit breaker comprising:



a housing,
an electrical conductor passing through the housing,
at least one blade, able to move so as to cut at least one portion of the electrical conductor, the breaking of the electrical conductor defining a cut area separating a first cut end of the electrical conductor from a second cut end of the electrical conductor,
a pyrotechnic actuator,

the circuit breaker having a first arc path allowing a first electric arc to be established directly from the first cut end to the second cut end,

characterized in that the circuit breaker comprises conductive cooling features so as to have a secondary arc path passing through a first conductive cooling feature and through a secondary conductive cooling feature or a last conductive cooling feature.
