摘要： A method for adjusting the calibration of a circuit breaker trip mechanism including a terminal element, a bimetal element connected thereto, and a trip bar. Laser energy is applied to lanced or pre-bent surfaces of the terminal element to thermally induce displacement thereof and thereby modify a trip distance between the bimetal element and the trip bar. Where a laser beam is directed to fall on a middle leg of a lanced or pre-bent section of the terminal element, the bimetal element moves in one direction relative to the trip bar. Conversely, where a laser beam is directed to fall on lateral legs of the lanced or pre-bent section of the terminal element, the bimetal element moves in an opposite direction relative to the trip bar. Thus, laser energy may be applied from the same direction, or to the same side of the trip structure, regardless of whether the trip time is to be increased or decreased.
摘要翻译：一种用于调整断路器跳闸机构的校准的方法，该断路器跳闸机构包括端子元件，与其连接的双金属元件和跳闸杆。将激光能量施加到端子元件的拉伸或预弯曲表面以热引起其位移，从而改变双金属元件和跳闸杆之间的跳闸距离。在激光束被引导落到终端元件的拉伸或预弯曲部分的中间腿部的情况下，双金属元件相对于跳闸杆在一个方向上移动。相反，当激光束被引导落到端子元件的拉伸或预弯曲部分的侧向腿上时，双金属元件相对于跳闸杆沿相反方向移动。因此，不管是否增加或减少跳闸时间，激光能量可以从同一方向或跳闸结构的同一侧施加。

摘要： A circuit breaker housing includes a base having a main portion and a separate subbase portion. The line contact arms for the breaker are mounted on the subbase portion and attached to the main portion which includes the load contact arms. The main portion of the base includes a bottom wall which insulates the load contact arms from the line contact arms along a portion of their lengths. In addition, the bottom wall forms a structural member which rigidly ties the two sidewalls of the main portion of the base. The bottom wall of the main portion of the base includes an opening through which line contacts coupled to the line contact arm make contact with load arm contacts coupled to the load contact arms. Adjacent to the opening, the main portion of the base includes vertical ribs directly tied to the bottom wall which strengthen internal and external side walls in the main portion of the base and reinforce the structural member formed by the bottom wall of the main portion of the base. The subbase may be attached to the base with screws, adhesives, a combination of screws and adhesives or by other methods.

摘要： A contact assembly (22) is adapted for use with a circuit breaker (12) that is set to open a circuit above a predetermined current load. The contact assembly (22) is adapted to reciprocate between a closed position to permit the flow of current through the circuit and an open position to prevent the flow of current. The contact assembly (22) is further adapted to resist unintended reciprocation from the closed position to the open position at current loads up to or exceeding the predetermined current load. The contact assembly includes a line side conductor (38) and a load side conductor (54). When in the closed position, a surface (42) of the line side conductor (38) extends proximal to a surface (56) of the load side conductor (54) and current flows in substantially the same direction along the line side and load side surfaces (42 and 56) to generate an electromagnetic attraction between the conductors (38 and 54) in order to resist unintended reciprocation of the contact assembly (22) from the closed position to the open position due to inherent repulsion forces present across the contact points (contact constriction forces). A circuit breaker assembly (10) and an automated control system (300) are also described.

摘要： A remote tripping mechanism for use with a spring loaded safety switch. In a preferred embodiment, the mechanism is made up of two cams with a compression type trip spring anchored between them. The two cams are held in the "normal position" (the spring compressed) by a latch. In this position, the switch operates in the same manner as a conventional safety switch. A trip lever connected to a solenoid is positioned such that it is unobtrusive when the switch is turned ON and OFF. When the switch is in the ON position and power is applied to the solenoid, the trip lever unlatches the latch and the two cams separate. The first cam engages and lifts the bail, turning the switch OFF. The cams are reset by turning the handle to the OFF position. This compresses the trip spring and resets the latch.
