Abstract
The invention relates to a switch circuit breaker protection circuit and a switch circuit breaker protection system capable of automatically resetting an accident total signal. According to the switch circuit breaker protection circuit capable of automatically resetting the accident total signal, a first relay is configured to receive a phase selection switching-on signal, a phase selection switching-off signal, a non-phase selection switching-on signal and a non-phase selection switching-off signal, so that when any one of the phase selection switching-off signal and the non-phase selection switching-off signal is input to the first relay, the accident total signal can be automatically reset; the first excitation switch on the excitation branch can be driven to be cut off when the accident total signal is output, and after the first excitation switch is cut off, the accident total signal generation branch is correspondingly driven to stop outputting the accident total signal, so that the accident total signal generation branch which is outputting the accident total signal is reset.
