    • A power switch disposed in a housing includes a contact breaker configured to connect and disconnect a low-voltage switchgear from a power source supplying the low-voltage switchgear, a triggering device configured to disconnect the low-voltage switchgear in an overload event, a current detection device, a control device, a first evaluation device configured to evaluate an accidental arc overcurrent, and a second evaluation device configured to evaluate the accidental arc overcurrent. The power switch is configured to be activated via an overcurrent signal generated by an arc monitoring system in response to the accidental arc overcurrent. The overcurrent signal is linked to the at least one triggering signal. The second evaluation has a threshold above a threshold of the first evaluation device. The triggering device is configured to be activated via a turn-off pulse when a signal from the current detection device is above the threshold of the second evaluation device.
    • 设置在壳体中的电源开关包括接触断路器,其被配置为将低压开关设备与供应低压开关设备的电源连接和断开;触发装置,其被配置为在过载事件中断开低压开关设备,电流 检测装置,控制装置,被配置为评估意外的过电流的第一评估装置,以及被配置为评估意外的电弧过电流的第二评估装置。 电源开关被配置为通过由电弧监视系统响应于意外的电弧过电流而产生的过电流信号而被激活。 过电流信号与至少一个触发信号相连。 第二评估具有高于第一评估装置的阈值的阈值。 触发装置被配置为当来自当前检测装置的信号高于第二评估装置的阈值时通过关断脉冲被激活。
