Abstract
A circuit breaker includes at least one electrical conductor for connection to an electrical circuit, a housing, a die, a punch movable relative to the housing to pass from a first position to a second position, and a pyrotechnical actuator to make the punch pass from the first position to the second position when ignited. The punch passes from the first position to the second position to cut the at least one electrical conductor into at least two distinct parts, and establish between the punch and the die, at least one electrical arc between the at least two distinct parts when the circuit breaker is connected to a live electrical circuit. When the punch is in the second position, at least one passage is between the at least two distinct part guides the at least one electrical arc between the distinct parts. A punch die unit includes at least one material designed to be withdrawn by ablation by the at least one electrical arc for generating gas suitable for increasing a voltage of the at least one electrical arc.
