ABSTRACT:
An air circuit breaker ratcheting mechanism includes a ratchet and pawl whereby the closing springs charging gear is prevented from reverse rotation during the closing springs charging operation. Upon completion of the charging operation, the ratchet and pawl become disengaged from the charging gear to allow the closing springs to respond to a manual closing button depression. A holding prop within the ratcheting mechanism interacts with a roller bearing on the charging shaft to prevent reverse rotation of the charging shaft under the bias provided by the charged closing springs.
