Abstract

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.
