摘要： Circuit-breaker system having a response time to shortcircuits of less than 4 milliseconds have multiple coordinated pole units wired in series in each phase. The system is able to clear a fault where the available current is high, for example 100,000 amperes at 240 volts AC although each pole unit may be of conventional construction having a current-interruption rating of only 5 or 10 thousand amperes. The operation exhibits current limiting properties, and the interruption process leaves the pole units remarkably free of arc damage.
