Abstract (en)
This automatic circuit breaker comprises mechanisms which effect normal closing and normal opening of the circuit breaker, opening by thermal tripping, opening by magnetic tripping and opening by short-circuiting. The mechanism for normal closing and normal opening of the circuit breaker consists of a handle (M), a handle spring (14), a link rod (11), a moving contact (CM) and a multifunction mechanism spring (21), with tripping by the bearing of the free end of the link rod upon the bearing point (28) of the spring (21). The electromagnetic opening device has a fixed contact (CF) acting as a magnetic shell, the arrangement of which within this device makes it possible to obtain a magnetic tripping mechanism having no fixed core and no spring for positioning the moving core. <IMAGE>
