摘要： An adjustable magnetic trip device for a molded case circuit breaker is provided where the trip device includes a plunger and a stationary core as well as a plunger support structure with a movable plunger carriage. The position of the plunger assembly and carriage relative to the stationary core is determined by a cam assembly having a body with a plurality of sections, each section having a different radius. The plunger carriage is responsive to rotation of said cam assembly and may be adjusted by rotating the cam. The over-current condition for the trip device is a function of the distance between the plunger assembly and the stationary core. Accordingly, the over-current condition may be changed by rotating the cam. As each section of the cam has a constant radius, the over-current condition remains the same no matter where the carriage contacts a certain section of the cam.
摘要翻译：提供了一种用于模制外壳断路器的可调磁脱扣装置，其中跳闸装置包括柱塞和固定芯以及具有可移动柱塞滑架的柱塞支撑结构。柱塞组件和托架相对于固定芯的位置由具有多个部分的主体的凸轮组件确定，每个部分具有不同的半径。柱塞滑架响应于所述凸轮组件的旋转，并且可以通过旋转凸轮来调节。跳闸装置的过电流状态是柱塞组件和固定芯之间的距离的函数。因此，可以通过旋转凸轮来改变过电流状态。由于凸轮的每个部分具有恒定的半径，所以无论载架与凸轮的某一部分接触的情况，过电流状态都保持不变。

摘要： An improved circuit breaker having an improved shield apparatus provides protection to components that are internal to the circuit breaker during an arc event. A contact arm carrier assembly of the circuit breaker comprises a number of springs that bias a number of movable contacts that are disposed on contact arms into engagement and electrical connection with a stationary contact. The shield apparatus is disposed on a carrier housing of the contact arm carrier assembly and is situated adjacent the springs. A shield member of the shield apparatus is biased into engagement with the contact arms. When the circuit breaker is moved between the ON position and the OFF or TRIPPED positions, the shield of the shield apparatus moves between a retracted position and a deployed position, with the shield remaining in engagement with the contact arms and protecting the springs from damage in an arc event. In one embodiment, the shield member is formed of a material that generates gases when struck by an arc.

摘要： An adjustable magnetic trip unit for a circuit breaker includes a torsion spring which applies a bias force to the plunger of a trip solenoid. The torsion spring is mounted on a driven bevel gear and wound by an adjustment knob coupled to a driving bevel gear to adjust the current at which the solenoid is activated. An indexer having peripheral flats which engage a seat in the circuit breaker housing provides a plurality of discrete positions of the adjustment knob. Depressing the adjustment knob against a second spring unseats the indexer for rotation of the adjustment knob between settings. In addition, a slide with an inclined surface bearing against the plunger and coupled to the driven bevel gear, provides simultaneous adjustment of plunger gap with adjustment of the torsion spring force to increase the range of adjustment.

摘要： A circuit interrupter including a housing, separable main contacts within the housing, and an operating mechanism within the housing and interconnected with the separable main contacts. A trip mechanism is disposed within the housing that includes a trip bar assembly rotatable about an axis and that, when rotated, generates a tripping operation causing the operating mechanism to open the contacts. The trip bar assembly includes a trip member translatable along the axis. The trip mechanism includes a tripping actuator movable along a predetermined path of travel as a function of electrical current. The tripping actuator contacts a contact area of the trip member at a predetermined location along the predetermined path of travel of the tripping actuator and causes the trip bar assembly to rotate and generate the tripping operation upon a predetermined current threshold. When the trip member is translated along the axis, the contact area is contacted by the tripping actuator at a different location along the predetermined path of travel of the tripping actuator whereby the predetermined current threshold is changed.

摘要： A circuit breaker including a housing, separable contacts, a cradle rotatably mounted within the housing, an alarm switch mounted within the housing, and an interface lever disposed between the cradle and the alarm switch. The cradle is adapted to rotate about a first axis in a first direction when the circuit breaker moves to a tripped position in which the separable contacts are separated from one another. The alarm switch includes an actuation lever movable in an actuation direction, wherein movement of the actuation lever in the actuation direction causes the alarm switch to activate an alarm device electrically connected thereto. When the cradle rotates in the first direction, the cradle exerts a first force against the interface lever that causes the interface lever to exert a second force against the actuation lever that causes the actuation lever to move in the actuation direction.

摘要： A circuit interrupter including a housing, separable main contacts within the housing, and an operating mechanism within the housing and interconnected with the contacts. An arc extinguisher assembly is disposed within the housing. Also provided within the housing is a slot motor assembly having a cavity region within which the contacts are substantially located. The slot motor assembly electro-magnetically interacts with current flowing between the contacts, and includes magnetic plates positioned in a slot motor housing. The slot motor housing has a tendency to move an arc existing between the contacts toward the arc extinguisher assembly. The slot motor assembly also includes an insulation member positioned within the cavity region and between the magnetic plates and the slot motor housing.
