Abstract

The invention related to a pyrotechnic circuit breaker (1) comprising: a body (10), a piston (40) slidably mounted in said body along a first direction (Z), said piston having a first protrusion (42) comprising a cutting edge (42a), a pyrotechnic igniter (30), and a bus bar (50). The piston is adapted to move from a raised position to a lowered position to cut the bus bar into two distinct portions (50a, 50b) upon activation of the pyrotechnic igniter (30). The piston further comprises a second protrusion (44a) extending from the lower face (43) over a greater distance (dl) than the first protrusion (d2). The bus bar (50) comprises an aperture (52a) aligned along the first direction (Z) with said second protrusion (44a), the second protrusion and the aperture being adapted to cooperate such that the second protrusion is engaged in the aperture when the piston moves from the first position to the second position.
