摘要

A short-circuiting device, with a short-circuiting piston (5) driven by a gas generator (6) for electrically connecting a terminal bar (3) to a connection bar (2), is new. A short-circuiting device has a short-circuiting piston (5) which is guided and retained in a connection bar (2) and which is driven, for electrical connection of a terminal bar (3) to the connection bar (2), by a gas generator (6) embedded in an insulating holder (7) which has a front space (31) and which is connected to the connection bar (2).
