摘要： PROBLEM TO BE SOLVED: To provide an overcurrent tripping device of a circuit breaker which prevents a delay in overcurrent tripping action to improve current-breaking performance. SOLUTION: Between a heater 9c disposed on a current path and a trip bar 24 of a switching mechanism 15, a bimetal 26 is disposed with its base end fixed to the heater and its front end extended toward the trip bar, and a runoff tab 27 is fixed to the tip of the bimetal with a free end thereof located near the trip bar. A flow of overcurrent through the current path causes the heater to generate heat so that the tip of the bimetal is heated and bent. This bending of the bimetal tip results in a shift in the position of the free end of the runoff tab, which eventually comes in contact with the trip bar. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种防止过电流跳闸动作的延迟以提高断流性能的断路器的过电流跳闸装置。解决方案：在设置在电流路径上的加热器9c和切换机构15的跳闸杆24之间，设置双金属片26，其基端固定在加热器上，其前端朝向跳闸杆延伸，并且径流片27固定在双金属片的尖端，其自由端位于跳闸杆附近。通过电流路径的过电流使得加热器产生热量，使得双金属片的尖端被加热和弯曲。双金属尖端的这种弯曲导致径流片的自由端的位置偏移，其最终与跳闸杆接触。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To facilitate the assembling of a trip crossbar to thereby reduce working man-hours.
SOLUTION: A circuit breaker comprises a latch receiver for locking a latch of a switching mechanism, and a trip crossbar for locking the latch receiver. The trip crossbar is rotatably supported by both side plates of a frame of the switching mechanism via a pin inserted to a shaft core. An end of the pin 6 inserted to the trip crossbar 1 is inserted to a pin hole 5 formed in one of the side plates of the frame 4, and the other end of the pin 6 is engaged in a pin groove 39 formed in the other side plate of the frame 4 by cutting. The trip crossbar 1 is thereby supported by the frame 4 and the pin 6 is held in the pin groove 39 by means of the pressing force applied to the trip crossbar 1 from the latch receiver. The assembling work for the trip crossbar 1 is facilitated since it is only necessary that only an end of the pin 6 inserted to the trip crossbar 1 in advance be inserted into the pin hole 5 of the frame 4 while the other end be engaged in the pin groove 39 of the frame 4.
