Abstract:
The invention relates to a pyrotechnic fuse for interrupting an electrical circuit, comprising a body (9), in which an explosive charge is disposed, wherein: the pyrotechnic fuse comprises a hollow cylinder (11), in which a piston (12) is disposed, beneath which a separation claw (13) is disposed, beneath which the conductor (20), which is to be severed, is disposed; the piston (12) and the separation claw (13) are pressed downwards once the pyrotechnic fuse has been triggered, and the separation claw (13) severs the conductor (20) at two points; a quenching substance storage chamber (14) is disposed outside the cylinder (11), which quenching substance storage chamber, as a result of the piston being pressed downwards once the pyrotechnic fuse has been triggered, is opened towards a separation chamber (15) such that the quenching substance moves into the separation chamber.
