器は再び投入状態に復帰しなければならない。It is suitable for such a wiring breaker upper automatic breaker. A high-level automated middle-load system is placed between the home lead-in route and a branch using a plurality of conventional circuit breakers. If a short circuit occurs after the interrupter for branch wiring, the upper automatic interrupter S is for the current wiring and the main contact must be opened to back up the interrupter. . When the short circuit is interrupted, the upper automatic interrupter must return to the closed state again.

る。On the other hand, if a short circuit occurs between the upper-level automatic interrupter and the wiring disconnector, the upper-level automatic interrupter will not respond automatically (it must take care of the disconnection alone). In other words, wiring cut-offs must be prioritized over higher-level automatic interrupters, and higher-level automatic interrupters must be prioritized over house entrance fuses.
This selection behavior is required not only for short-circuit currents (but also for overload currents that last for a relatively long time). Accordingly, this invention is vPIII!IKmg#I.
