Abstract (en)

[origin: WO2022017841A1] Disclosed is a pyrotechnic circuit breaker comprising: - a housing (10), - at least two connection terminals (21, 22); - an internal electrical circuit linking the two connection terminals (21, 22) and consisting, for example, of an electrical conductor; - an opening member (40) that is movable and configured, when moving between an initial position and a final position, to open a section of the internal electrical circuit intended to be opened, thus forming at least two separate conductor portions (32, 33) after opening; - a pyrotechnic actuator (50) for moving the opening member (40) from the initial position to the final position; - an internal chamber (60) receiving the section to be opened, characterised in that the internal chamber includes or contains at least one inner surface formed by a wall consisting of a plastic material including a flame retardant.
