摘要：
Operating mechanism for actuating an operating rod (13) of a circuit-breaker including at least one interrupter chamber filled with a pressurized dielectric gas, said operating mechanism using a tripping spring (21) held charged when the circuit-breaker is closed by a selectively operable tripping abutment (23). The operating mechanism has a resetting member formed by a member (34) moving through a wall of a sealed and closed enclosure (32) communicating with the pressurized interrupter chamber.
