ABSTRACT:
An air circuit breaker closing spring charging mechanism includes a ratchet and pawl whereby the closing spring charging gear is protected from damage due to reverse rotation of the ratchet when the charged closing springs are later released. A locking latch prevents damage to the charging mechanism components and a latch release lever allows the charging mechanism to return to an operative position when the closing springs are later charged by a manually operated charging handle.
