A circuit breaker includes a set of main separable contacts, an operating mechanism for operating the main separable contacts, a set of secondary separable contacts in series with the main separable contacts, and a solenoid mechanism for operating the secondary separable contacts. A first auxiliary switch is responsive to the operating mechanism, and a second auxiliary switch, electrically connected to the first auxiliary switch, is responsive to the solenoid mechanism. An input terminal for a control voltage is electrically connected to the first and second auxiliary switches. A first diode is electrically connected with a forward polarity between the first auxiliary switch and an output terminal. A second diode is electrically connected with a reverse polarity between the second auxiliary switch and the output terminal.

Disjoncteur comportant une série de contacts principaux séparables, un mécanisme pour commander lesdits contacts, une série de contacts secondaires séparables en série avec les contacts principaux séparables et un mécanisme à solénoïde pour commander les contacts secondaires séparables. Une premier commutateur auxiliaire réagit au mécanisme de commande, et un second commutateur auxiliaire branché électriquement au premier commutateur auxiliaire réagie au mécanisme à solénoïde. Une borne d'entrée pour une tension de commande est branchée électriquement au premier et au second commutateurs auxiliaires. Une première diode est reliée électriquement à la polarité avant entre le premier commutateur auxiliaire et la borne d'entrée. Une seconde diode est reliée électriquement avec la polarité inversée entre le second commutateur auxiliaire et la borne d'entrée.
