摘要
An operating mechanism for a circuit-breaker, for carrying out an O-C- O cycle, followed by a C-O cycle, includes a tripping spring and a setting spring, coaxial with each other. Expansion of the setting spring compresses the tripping spring. The setting spring is compressed by an arrangement coaxial with the springs including a reversible electric motor.
