<p>In order to make it possible for a plurality of individual switch poles (1, 2, 3) of a multipolar circuit breaker to switch as synchronously as possible, a tie rod (7, 8) is provided which transmits a mechanical release pulse to the release devices (9, 9a, 10, 11) of the individual poles (1, 2, 3). Drive levers (13, 27, 28) to convert the movement into a release movement are articulated on the tie rod (7, 8). The tie rod (7, 8) is driven suddenly by a shaft (19), by means of release arms (20, 23) and levers (17, 17a) which are mounted in a fixed position. <IMAGE></p> |
