ABSTRACT:
A multipolar circuit breaker is provided for securely operating tripping sections of other poles when the tripping section of any pole operates. In the case of a first embodiment, a protrusion 5 for further moving a trigger plate in the tripping direction when a cradle 3 is tripped is provided for the cradle 3 of each pole so that the movement of the trigger plate 1 is securely transmitted to other poles connected by a trigger joint 2. Moreover, in the case of a second embodiment, a protrusion for further moving the trigger plate 1 in the tripping direction by pushing the cradle 3 when the cradle 3 is tripped is provided for the trigger plate of each pole to obtain the same above mentioned advantage.
