    摘要: A multi-pole circuit interrupter comprising first and second pole units separated by a partition wall in a housing, each of the pole units having a pair of separable contacts. The contacts of the first and the second pole units are connected by a cross bar for simultaneous movement. An operating mechanism is disposed in the first pole unit for separating the contacts in response to an overcurrent flowing through the interrupter. An alarm switch is disposed in the second pole unit for indicating the tripping of the operating mechanism, and an actuator is disposed between the operating mechanism and the alarm switch for detecting the tripping of the operating mechanism and actuating the alarm switch. The actuator comprises a rotatable shaft supported in the housing and extending through the partition wall including a substantially circular opening having a diameter slightly larger than that of the rotatable shaft, an actuator arm secured to one end of the rotatable shaft for movement caused by the tripping action of the operating mechanism, and an actuator level secured to the other end of the rotatable shaft for engaging and actuating the alarm switch.

    摘要: A circuit breaker having a handle stop for restraining the handle in a "tripped" or central position after the circuit breaker is electrically tripped to mechanically and visually indicate the tripped position.Also, an actuator is supported within the case of the circuit breaker and pivoted by the linkage mechanism (only when the latter is electrically tripped). During manual opening and closing of the circuit breaker contacts, the linkage mechanism does not pivot the actuator.Pivoting of the actuator (upon electrical tripping of the linkage mechanism) causes the actuator to engage and activate an auxiliary switch.When the circuit breaker handle is moved to the "off" position from the "tripped" or central position, the linkage mechanism simultaneously releases the actuator and the auxiliary switch is deactivated.

    摘要: A circuit interrupter to trip on occurrence of ground faults or the like in which the neutral and electrified contacts are mounted to open and close in a pre-determined sequence when being reset. When closing to reset the mechanism, the neutral contacts make first and the "hot" or electrified contacts can only make after the neutral contacts have closed. On pushing the reset button to open, the converse is true. The hot or electrified contacts break first and the neutral contacts can break only after the electrified contacts have separated and interrupted the hot conductor. This sequential operation protects the circuit from an inadvertent making of the hot contacts while the neutral contacts were still open. Under such condition, the circuit would be electrified but there would be no ground fault protection. The ground fault interrupter would not be powered as long as the neutral contacts remain open. A resistor is connected between the ground terminal and the neutral conductor on the load side of the breaker to protect against cross wiring the line conductors to the ground fault interrupter terminals. If the hot or electrified line conductor is mistakenly cross-wired to the neutral terminal of the ground fault interrupter, the resistive connection between neutral and ground simulates a ground fault condition and causes the mechanism to trip. It cannot be reset as long as the hot wire is connected to the neutral terminal of the interrupter.

    摘要翻译: 电路断路器在发生接地故障时发生跳闸等,其中中性和带电触点安装成在复位时以预定的顺序打开和关闭。 当关闭以复位机构时,中性触点首先产生,并且“热”或电气触点只能在中性触点闭合之后进行。 按下复位按钮打开,反之亦然。 热或电气触点首先断开,中断触点只有在电气触点分离并中断热导体之后才会断开。 这种顺序操作保护电路免受热触点的不小心制造,同时中性触点仍然打开。 在这种情况下,电路将通电,但不会有接地故障保护。 只要中性触点保持断开,接地故障断路器就不会通电。 接地端子和断路器负载侧的中性导体之间连接一个电阻器,以防止线路导线与接地故障断路器端子交叉接线。 如果热线或电气线路导体错误地交叉连接到接地故障断路器的中性端子,则中性线和地线之间的电阻连接模拟接地故障状态并使机构跳闸。 只要热线连接到断路器的中性端子,就不能复位。

    摘要: A circuit breaker having a handle stop for restraining the handle in a ''''tripped'''' or central position after the circuit breaker is electrically tripped to mechanically and visually indicate the tripped position. Also, an actuator is supported within the case of the circuit breaker and pivoted by the linkage mechanism (only when the latter is electrically tripped). During manual opening and closing of the circuit breaker contacts, the linkage mechanism does not pivot the actuator. Pivoting of the actuator (upon electrical tripping of the linkage mechanism) causes the actuator to engage and activate an auxiliary switch. When the circuit breaker handle is moved to the ''''Off'''' position from the ''''tripped'''' or central position, the linkage mechanism simultaneously releases the actuator and the auxiliary switch is deactivated.

    摘要: A SWITCH UNIT IN WHICH A PAIR OF CONTACT MEANS MOVABLE BETWEEN AN OPEN AND A CLOSED POSITION ARE ARRANGED IN A PAIR OF CHAMBERS FORMED IN A SOCKET, IN WHICH AN OPERATING MEMBER COOPERATES WITH ONE OF SAID CONTACT MEANS TO MOVE THE SAME BETWEEN THE OPEN AND THE CLOSED POSITION AND WITH THE OTHER CONTACT MEANS TO MOVE THE LATTER TO THE CLOSED POSITION, AND IN WHICH HEAT-RESPONSIVE MEANS COOPERATE WITH THE OTHER OF THE CONTACT MEANS TO MOVE THE LATTER FROM THE CLOSED TO THE OPEN POSITION WHEN OVERLOAD OCCURS IN THE CIRCUIT CONNECTED TO THE CONTACT MEANS. THE UNIT MAY ALSO INCLUDE A SIGNAL LAMP MOUNTED ON THE OPERATING MEMBER AND THE SIGNAL LAMP MAY BE CONNECTED TO THE CONTACT MEANS IN SUCH A MANNER THAT THE LAMP IS ENERGIZED EITHER WHEN THE OTHER CONTACT MEANS ARE IN THE OPEN OR WHEN THEY ARE IN THE CLOSED POSITION.
