Embodiment 1
[0045] Below in conjunction with accompanying drawing this embodiment is described in detail:
[0046] The present invention provides as Figure 1-9 A high breaking miniature circuit breaker is shown, including:
[0047] The handle structure 1 is rotated and arranged on the shell;
[0048] The tripping assembly 2, which cooperates with the handle structure 1, includes a runner 21 rotatably arranged on the housing. The tripping assembly 2 has a function to drive the runner 21 to rotate forward when the handle structure closes and moves. Closing state, and the opening state in which the runner 21 is driven to reversely rotate when the handle structure 1 is in the opening movement;
[0049] The contact structure includes a static contact 3 fixed to the housing, a moving contact part 4 which is movably arranged on the housing relative to the static contact, and a moving contact part 4 arranged between the moving contact part 4 and the The elastic member 5 between the housings, ...
