    • An electric circuit breaker including a current sensor composed of a Hall generator for detecting current overloads. Two secondary windings of a current transformer associated with the power line are connected to provide power to two separate power supply circuits. One circuit supplies power to a control circuit and the other circuit supplies control current to the Hall generator. The output voltage of the Hall generator is compared with a predetermined value in the control circuit. If a predetermined overload occurs, the control circuit energizes a trip coil for opening the power line.
    • 一种电路断路器,包括由用于检测电流过载的霍尔发生器组成的电流传感器。 与电力线相关联的电流互感器的两个次级绕组被连接以向两个单独的电源电路提供电力。 一个电路为控制电路供电,另一个电路为霍尔发生器提供控制电流。 将霍尔发生器的输出电压与控制电路中的预定值进行比较。 如果发生预定的过载,则控制电路激励用于打开电源线的跳闸线圈。
