摘要： A fastening assembly is for a circuit breaker. The circuit breaker has a base and a bimetal. The fastening assembly includes a heater element structured to be coupled to the bimetal and the base, and a plurality of fastening members including a nut and a coupling member coupled to the nut. The nut is structured to be disposed between the heater element and the bimetal. The coupling member extends through the heater element and into the nut in order to minimize movement of the heater element with respect to the base.

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： A removable keypad controls the electronic trip unit used within state-of-art electronic circuit breakers. The keypad allows inputting and displaying relevant circuit interruption information. Unauthorized access to the trip unit settings is prevented by blocking off the keypad "ENTER" key while still allowing access to the keypad's remaining function keys.

摘要： Disclosed is a gap adjusting method which easily adjusts a gap between a bimetal and a crossbar by using a gap adjusting block and an adjusting screw in a trip mechanism of a molded case circuit breaker without a separate additional device. The gap adjusting method in the trip mechanism of the molded case circuit breaker includes setting a reference gap between a crossbar and a bimetal, measuring a total resistance of the trip mechanism and a trip stroke of a switching mechanism to set a compensation gap, placing a gap adjusting block on a position separated from a crossbar by a gap based on the sum of the reference gap and the compensation gap, rotating an adjusting screw assembled with the bimetal to contact the adjusting screw with the gap adjusting block, and adhering the adjusting screw to the bimetal.

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。
