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 accessory includes a trip arm biased by a spring to pivot in a clockwise direction about a trip arm pivot. A latch is arranged to pivot about a latch pivot and has the trip arm acting on a latch surface on the latch to bias the latch in a counter clockwise direction about the latch pivot. An electromechanical device including a plunger acts on the latch pulling it clockwise about the latch pivot. When a signal is provided to the electromechanical device, the plunger is released allowing the trip arm to pivot clockwise about the trip arm pivot due to the spring and actuates the operating mechanism. To reset the trip arm and the latch, a reset lever is arranged to pivot about the latch pivot. The reset lever includes a tab portion configured for interfacing the operating mechanism, and a drive portion for interfacing the trip arm. This, when the operating mechanism is reset, a portion extending from an operating handle interfaces the tab portion to pivot the reset lever clockwise about the latch pivot. The drive portion interfaces the trip arm to drive the trip arm counterclockwise about the trip arm pivot.
