ABSTRACT OF THE DISCLOSURE: The electric control to reset the circuit breaker is formed by a sub-assembly being able to be easily coupled to the mechanism of the circuit breaker. At the end of the charging travel of the closing spring a control cam discon- nects and stops the motor. The charging position is defined by a latch interlocking the charging cam, a closing operation being induced by the release of the latch and a limited rotation of this charging cam. The link shaft between the motoreducing sub-assembly and the machanism transmits this closing limited rotation to the control cam, which induces the restarting and the connecting of the motor for a reset operation of the closing spring.
