ABSTRACT:
An electric compressed-gas circuit breaker is equipped with a blasting device for extinguishing the arc drawn when the breaker opens. The blasting device includes a cylinder member and a piston member as well as energy storage means which, at the start of the opening motion, is released in a direction to produce an additional compression. The energy storage means is charged at the end of the breaker opening motion with the kinetic energy of the parts moved by the drive for the blasting device.
