摘要:
A latch engagement control mechanism is provided for a latch assembly of a circuit breaker including a housing, separable contacts, and an operating mechanism having a pole shaft, and at least one link coupled to the pole shaft. The latch assembly includes a pivot member cooperable with such link. The latch engagement control mechanism includes a latch pin having a cut-out portion and pivoting among a first position in which the latch pin prevents the pivot member from pivoting, and a second position in which the cut-out portion provides a clearance for the pivot member to pivot. A latch member coupled to the latch pin at or about the cut-out portion, includes at least a first protrusion engageable by the pivot member to establish the first position of the latch pin.
