摘要： In accordance with one embodiment, the present technique provides a circuit interrupter. The exemplary circuit interrupter includes conductive spanner that completes an electrical pathway between first and second electrical conductors. To facilitate a good electrical connection between the conductive spanner and the first and second conductors, the exemplary interrupter includes a biasing mechanism that biases the conductive spanner toward the first and second conductors. However, in the event of a fault condition, for instance, the conductive spanner is displaced away from the first and second conductors by magnetic forces, and the electrical path is interrupted. To facilitate this displacement, the biasing mechanism presents an opposing force to displacement relationship with a negative slope. That is to say, the biasing force provided by the biasing mechanism decreases as the distance between the conductive spanner and the first and second electrical conductors increases. Additionally, pistons driven by arc heated gases engage the biasing mechanism to assist the magnetic forces during the interruption of soft faults.

摘要： A device for protection against voltage surges comprises a stationary electrode and a movable electrode arranged facing an arc extinguishing chamber. The movable electrode is driven by a mechanisms, by an electromechanical actuator and/or by an electromagnetic circuit. At rest, the movable electrode is situated at a distance from the stationary electrode. When a voltage surge occurs between the electrodes, an arc arises and extends in the chamber in which it is extinguished. If the arc continues, in particular in the case of a follow current of high energy, the movable electrode is driven to a disconnected position moving away from the stationary electrode, which has the effect of lengthening the arc even more in the chamber to facilitate its extinction and perform disconnection of the circuit. A pair of contacts may be associated in series to the electrodes, one of the contacts being stationary and the other being fixedly secured to the movable electrode. A spark gap can also be associated to the electrodes.
摘要翻译：用于防止电压浪涌的装置包括固定电极和面向消弧室布置的可动电极。可动电极由机构，机电致动器和/或电磁电路驱动。静止时，可动电极距固定电极一定距离。当在电极之间发生电压浪涌时，产生电弧并在其熄灭的室中延伸。如果电弧持续，特别是在高能量跟随电流的情况下，可移动电极被驱动到远离固定电极的断开位置，其具有在腔室中更多地延长电弧的作用，以便于其熄灭并断开电路。一对触点可以与电极串联连接，其中一个触点是固定的，另一个触点固定地固定在可动电极上。火花间隙也可以与电极相关联。

摘要： A molded case circuit breaker includes a switching mechanism and a current-interrupting section. The current-interrupting section is composed of an insulated case, fixed contact shoes arranged diagonally opposite to each other, a bridging rotary contact shoe, a contact shoe holder, and arc extinguishing devices. The fixed contact shoes are composed of linear contact shoe conductors to reduce a height of the section, and the fixed contact shoes are arranged vertically in parallel and opposite each other so that the fixed contact shoes and the rotary contact shoe form a Z-shaped conducting path.

摘要： A current limiting device includes first and second contact members, each contact member having, at a first end, contacts defining a contact pair; a contacting pressure is applied to said contact pair; and a cylindrical insulator cylindrically surrounding the contacts when the contacts are closed. The device is arranged such that at least one of the first and second contact members is rotatably supported at a second end. Also, an electrical path is defined through which currents flow in substantial opposition to the first and second contact members and in opposite directions to each other. The first ends of the first and second contact members are positioned within the space defined by the cylindrical insulator in the closed contact state. The contact of at least one of the rotatably supported contact members is positioned outside of the space defined by the cylindrical insulator when the contacts are open.

摘要： A molded case circuit breaker having an operating mechanism including a collapsible toggle linkage, an operating handle and a movable frame. The collapsible toggle linkage includes a rectangular cross section knee pin non-rotatably held within an open rectangular slot in an upper link of the linkage. The operating handle pivots about a first pivot point when moving between ON, OFF and TRIPPED positions. The operating handle pivots about a second pivot point when moving to a RESET position thereby reducing the lateral force component of the operating springs of the operating mechanism for reliable return of the handle to the OFF position. Also, bifurcated movable contact fingers are provided for pivotal movement about a fixed pin to break contact welds and a trapezoidal cross section shaft interconnects the movable contact fingers.

摘要： A molded case circuit breaker is provided. Key blocks with a key shaped projection along one side are received in key shaped grooves in the sidewalls of the base. The kay shaped projections and the key shaped grooves may be formed as a dovetail connection. These key blocks provide support for the sidewalls from forces resulting from relatively high overcurrent conditions, such as a short circuit condition. In addition to supporting the sidewalls, the key blocks also form a barrier between the main contacts and other components in the circuit breaker to reduce the amount of arc products allowed to interact with the other components in the circuit breaker. The key block also form a stop surface for capturing the arc chutes to prevent movement of the arc chutes along the longitudinal axis of the circuit breaker. Lastly, the key blocks also hold the insulation barrier on the line conductor in place, thus obviating the need to use adhesives.
