    • The invention relates to a circuit breaker for three-phase networks with a neutral conductor (N). The triggering behavior of a triggering device (1, 2, 3, 4) and a tripping device (5 to 12) for the neutral conductor is different from the triggering behavior for at least one other pole. According to the invention, the triggering (4) and/or the tripping device (8 and 12) for the neutral conductor (N) is coupled with the tripping device (5 to 7 and 9 to 11) for other poles, and/or the triggering device (4) for the neutral conductor (N) has a different nominal current to the triggering device or triggering devices (1 to 3) for other poles.
    • 用于与中性导线(N),三相系统的保护电路装置,其中从所述脱扣行为对于至少一个另外的极触发装置(1,2,3,4)和断开偏离(5至12),用于中性导线的跳闸特性。 可以设想,所述触发装置(4)和或中性导体(N)与耦合到其它终端设备和/或在该触发装置的切断装置(5至7和9至11)中的关断装置(8和12)(4 )(为的中性导线N)(跳闸装置或跳闸装置1〜3)的偏离在用于更多极点其额定电流。
