    • An undervoltage release device for a circuit breaker is disclosed having an operating mechanism, a trip bar, line and load terminals, and a cover. The device includes a housing, a solenoid, upper and lower actuators aligned with a plunger of the solenoid and in selective contact with the trip bar, plunger and actuator reset levers mounted upon the solenoid frame, and pair of terminals in electrical contact with the solenoid coil and line terminals of the breaker, wherein the force of the solenoid corresponds to the line voltage. Also disclosed is a method for tripping a circuit breaker when line voltage drops below a selected value, in a circuit breaker having an operating mechanism and a trip unit with an intermediate latch. The method includes steps of closing the circuit breaker with the operating mechanism, installing the device in a cover of the circuit breaker, the device having a solenoid with a plunger and a plurality of actuators in selective contact with the plunger and the trip unit; and wiring the solenoid in parallel with the load circuit, wherein the magnetic force of the solenoid is proportional to the line voltage and maintains the plunger in contact with the actuators, and wherein the plunger is released by the solenoid when the line voltage drops below the selected value, thereby providing for at least one actuator to contact the trip unit and open the circuit breaker.
    • 公开了一种用于断路器的欠电压释放装置,其具有操作机构,跳闸杆,线路和负载端子以及盖子。 该装置包括壳体,螺线管,与螺线管的柱塞对准的上部和下部致动器,并且与安装在螺线管框架上的跳闸杆,柱塞和致动器复位杆选择性接触,以及与螺线管电接触的一对端子 线圈和线路端子,其中螺线管的力对应于线路电压。 还公开了一种在具有操作机构的断路器和具有中间闩锁的跳闸单元的线路电压降低到选定值以下时断路器的跳闸方法。 该方法包括用操作机构关闭断路器的步骤,将设备安装在断路器的盖子中,该设备具有带柱塞的螺线管以及与柱塞和跳闸单元选择性接触的多个致动器; 并且将螺线管与负载电路并联连接,其中螺线管的磁力与线路电压成比例并且使柱塞保持与致动器接触,并且其中当线路电压降到低于该电压时,柱塞被螺线管释放 从而为至少一个致动器提供接触跳闸单元并打开断路器。

    • A method and an extended rotary operating mechanism for a circuit breaker having a movable operating handle coupled to a shaft, and electrical contacts, the extended rotary operating mechanism comprising a handle operator defining a socket. A blocking plate mounted in the socket, with the blocking plate including a blocking shape. A shaft adapter is coupled to the blocking plate and the shaft. If the electrical contacts of the circuit breaker are welded closed and a torque is applied to the operator handle, the blocking shape prevents the handle operator from being locked in an “OFF” position independently of the operating handle position, by covering a locking hole. The shaft adapter may include one of an extended socket and a recessed socket configured to engage the shaft.
    • 一种用于断路器的方法和扩展旋转操作机构,其具有联接到轴的可移动操作手柄和电触点,所述扩展旋转操作机构包括限定插座的手柄操作器。 安装在插座中的阻挡板,阻挡板包括阻挡形状。 轴适配器联接到阻挡板和轴。 如果断路器的电触点被焊接闭合并且向操作者手柄施加扭矩,则阻挡形状通过覆盖锁定孔而防止手柄操作者被锁定在独立于操作手柄位置的“关闭”位置。 轴适配器可以包括延伸插座和被配置为接合轴的凹入插座中的一个。
