摘要： An air circuit breaker bell alarm accessory interacts with the circuit breaker contact position indicator to provide local and remote indication of the occurrence of a circuit interruption. A drive pin extending from the bottom of the accessory interacts with a slot on the contact position indicator lever to reset the bell alarm accessory when the circuit breaker contacts are in the process of being closed.

摘要： An auxiliary switch activation mechanism is provided for use with a circuit breaker having an auxiliary switch and an operating mechanism for opening and closing main electrical contacts. The auxiliary switch activation mechanism includes a lever having a first end removably connectable to the operating mechanism, a second end of said lever removably connectable to the auxiliary switch, and a spring, mechanically coupled to the lever, which imparts a rotational bias on the lever. The lever provides an assisting force to the operating mechanism for opening the main electrical contacts.

摘要： 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.

摘要： 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, command. An operating handle pivot assembly allows a molded plastic handle operator to be employed and the ratcheting mechanism is arranged for modular assembly during the circuit breaker manufacturing process as well as motor to manual charge conversion one site.

摘要： An air circuit breaker bell alarm accessory interacts with the circuit breaker operating mechanism to provide local target indication as well as remote signal indication of the separation of the circuit breaker contacts. An indicator switch provides remote signal indication while a lock-out switch interacts with the accessory target to prevent re-closure of the circuit breaker contacts. One of the switches is selected having "normally open" contacts while the other switch is selected having "normally closed" contacts to reduce the amount of mechanical force required to simultaneously operate the indicator and lock-out switches.

摘要： A circuit breaker contact closing solenoid assembly within an air circuit breaker includes an upper drive link connecting between a lower drive link and the circuit breaker closing prop driver to release the closing prop driver post from the charging ratchet retainer post. Actuation of the circuit breaker closing solenoid rotates the upper and lower links to allow the charging ratchet to rotate and release the charged closing springs and drive the circuit breaker contacts to the CLOSED condition.
