    • A circuit breaker includes a housing having an open top and a closed bottom, with a button pivotally connected to the housing at the open top, and with a grounding prong, an output blade and an input blade extending out of the housing through the closed bottom. The output blade has an inner end provided with a first contact. The input blade has an inner end formed with a bimetal strip that is provided with a second contact normally engaged with the first contact. The button is further formed with a leg extending towards the strip, and a hook is pivotally connected to the leg and has an arm beneath the strip. A neon indicator has first and second terminals. The second terminal is electrically connected to the output blade, and a resistor is electrically connected between the grounding prong and the first terminal of the neon indicator.
    • 断路器包括具有敞开的顶部和封闭的底部的壳体,具有在开口顶部处枢转地连接到壳体的按钮,并且具有接地插脚,输出叶片和输入叶片,其通过封闭的底部延伸出壳体 。 输出叶片具有设置有第一接触件的内端。 输入叶片具有形成有双金属条的内端,双金属带设置有与第一接触件正常接合的第二接触。 按钮进一步形成有朝向条带延伸的腿部,并且钩子枢转地连接到腿部并且在条带下方具有臂。 霓虹灯指示灯具有第一和第二端子。 第二端子电连接到输出叶片,并且电阻器电连接在接地插脚和氖指示器的第一端子之间。

    • A circuit breaker with a bimetal actuated latch, which controls both tripping and an overload indicator switch, is provided for emergency control the bimetal actuated latch is adjustable by a remotely controlled emergency control electric operator. An emergency control limit switch is provided so that the status of the emergency control electric operator can be remotely monitored. The circuit interrupter also has a remotely actuated motor operator which is controlled by a limit switch and cam arrangement to automatically shut off at the on and off positions of the circuit interrupter. A contact limit switch is provided to be actuated when the contacts of the circuit interrupter are open to indicate the status of the circuit interrupter. A remotely controlled reset solenoid is provided for resetting the overload indicator switch after it has been released by the bimetal actuated latch.
    • 提供控制脱扣和过载指示器开关的双金属致动闩锁的断路器用于紧急控制,双金属致动闩锁可由遥控应急控制电动操作器调节。 提供了一个紧急控制限位开关,可以远程监控应急控制电气操作员的状态。 电路断路器还具有远程致动的电机操作器,其由限位开关和凸轮装置控制,以在断路器的接通和断开位置处自动切断。 当断路器的触点断开以指示电路断路器的状态时,提供接触限位开关以被致动。 提供了一个远程控制的复位电磁阀,用于在过载指示开关被双金属驱动的锁闩释放之后复位。
