    • A ground fault circuit interrupter device having a feedthrough capacitor for substantially reducing interference from radio frequency signals such as those emitted from cell phones and 2-way radios. The ground fault circuit interrupter device includes a printed circuit board having a system ground terminal and a detection terminal for receiving a fault detection signal. A chip is provided having a ground pin connected to the system ground terminal and an input pin for receiving the fault detection signal. The feedthrough capacitor has a through conductor connected between the input pin and the detection terminal and a capacitor coupled between the through conductor and the system ground terminal.
    • 一种具有馈通电容器的接地故障电路断续器装置,用于大大减少来自诸如从手机和双向无线电发射的射频信号的射频信号的干扰。 接地故障电路断路器装置包括具有系统接地端子的印刷电路板和用于接收故障检测信号的检测端子。 提供了具有连接到系统接地端子的接地引脚和用于接收故障检测信号的输入引脚的芯片。 馈通电容器具有连接在输入引脚和检测端子之间的贯通导体以及耦合在贯通导体与系统接地端子之间的电容器。

    • A device for providing ground fault protection for one or more loads in an electrical wiring system. The device includes a pickup for sensing electrical characteristics associated with conductors supplying power to the one or more loads and generating a pick up signal when predefined electrical characteristics are sensed; a ground fault detector powered using conductors that are independent of the conductors supplying power to the one or more loads, said ground fault detector being configured to receive said pickup signal, detect ground faults from said pickup signal, and generate a trigger signal when a ground fault is detected, and a power disconnect responsive to said trigger signal such that when said trigger signal is generated power to the one or more loads is disconnected. A corresponding method is also provided.
    • 一种用于为电气布线系统中的一个或多个负载提供接地故障保护的装置。 该装置包括拾取器,用于感测与向一个或多个负载供电的导体相关联的电特性,并且当感测到预定义的电特性时产生拾取信号; 接地故障检测器,使用独立于向所述一个或多个负载供电的导体的导体供电,所述接地故障检测器被配置为接收所述拾取信号,从所述拾取信号检测接地故障,并且在接地时产生触发信号 检测到故障,以及响应于所述触发信号的电源断开,使得当所述触发信号产生到所述一个或多个负载的电力时被断开。 还提供了相应的方法。
