Abstract
The invention relates to a plug-in circuit breaker and has the object of preventing no-load discharges of the closing mechanism when extraction of the circuit breaker is performed. The drive mechanism of the circuit breaker loading and closing mechanism comprises a trip mechanism which is able to move from a closed state wherein actuation of an oscillating lever is designed to move the closing spring to its loaded state, to a tripped state wherein actuation of the oscillating lever is designed to prevent movement of the closing spring to its loaded state. This trip mechanism causes either disengagement of the oscillating lever or neutralization of a free-wheel coupling of the drive mechanism. The circuit breaker is moreover equipped with opening and closing controls causing an opening, closing, opening cycle when extraction is performed.
