I can not help but wonder why these type of high value aircraft use circuit breakers rather than fuses. Circuit breakers are in essence no more than a mechanical switch (we all use those I believe) activated by heat rather than a finger. But, this debate could (has and will) continue into the future, for sure.
For the planes that have a gajillion and one circuits, the breakers can serve as a switch for maintenance or troubleshooting of a portion of a component system. The switch on the panel may turn the whole system ON or OFF.. an individual actuator or motor may have its own breaker.. for example..
