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 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.

摘要： The circuit breaker (10) of the present invention is a molded case circuit breaker and includes a molded case (12) having a main cover (20), a first terminal (16) and a second terminal (16) mounted inside the case (12) with a stationary contact (44) electrically coupled to the first terminal (18) and a movable contact (42) electrically coupled to the second terminal (16). The movable contact (42) is coupled to an operating mechanism (40) which has a pivoting member (13) moveable between an ON position, an OFF position and a TRIPPED position. An intermediate latching mechanism (52) also is mounted in the housing (12) and is coupled to the operating mechanism (40). The intermediate latching mechanism (52) is selectively operated by a trip unit (60) which comprises a magnetic short circuit release and a thermal overload release. The trip unit (60) can be reconfigured by the addition of an inner yoke (67) nested between the flanges (71) of an outer yoke (66) and a second magnetic shield (70) can be attached to the outer yoke (66) to change the sensitivity of the trip unit (60) to the currents experienced by the circuit breaker. A particular embodiment of the circuit breaker (10) includes an interchangeable bi-metal (62) member of a copper alloy having a chemical composition of CDA #19400 and with an electrical conductivity of not more than 40% IACS.

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.

摘要： A circuit breaker (10) has a housing (12). A crossbar (114) is pivotally connected to the housing to pivot about an axis (117) between open and closed positions. A load contact arm (110) is pivotally connected to the crossbar (114). The load contact arm (110) is capable of pivoting about the axis (117). A cam mechanism (140) is mechanically coupled to the load contact arm (110). The cam mechanism (140) is slideably mounted within the crossbar (114) for movement between first and second positions. In the first position of the cam mechanism (140), the load contact arm (110) pivots through an angle (.beta.) about the axis, relative to the crossbar (114) between the "touch" and closed positions, and the load contact arm (110) pivots together with the crossbar (114) through an angle (.alpha.) about the axis (117) between the open and "touch" positions. (2) In the second position of the cam mechanism (140), the load contact arm (110) is free to pivot about the axis (117) through the angle .alpha. to the open position while the crossbar (114) is in the closed position. A biasing spring (160) applies a biasing force to bias the cam mechanism (140) towards the first position.
