Abstract

The electric control to reset a circuit breaker is formed by a sub-assembly (10) to be coupled to the mechanism (60) of the circuit breaker. At the end of the charging travel of the closing spring a control cam (46) disconnects and stops the motor. The charging position is defined by a latch interlocking the charging cam (62), a closing operation being induced by the release of the latch and a limited rotation of this charging cam (62). The link shaft between the motor reducing sub-assembly or block (10) and the mechanism (60) transmits this closing limited rotation to the control cam (46), which induces the restarting and the connecting of the motor for a reset operation of the closing spring.
