Methods and systems for suppressing arc formation in branch breakers provide a load center that can monitor a branch breaker for indications of arc formation. The load center may include a main breaker that can immediately cut current to the upon receiving an indication of an arc forming in the branch breaker. The indication may be provided by a sensor circuit that sends a trigger signal to the main breaker when arc formation is detected within the branch breaker. The main breaker checks that the trigger signal indicates arc formation, then cuts current to suppress the arc. The main breaker then waits a short period for the branch breaker to clear before restoring current. The wait period is sufficiently short such that devices receiving power from the load center are not adversely affected. To improve cutoff and restoration response times, the main breaker employs a solid-state trip switch.
