Abstract:
A latching assembly for latching the moving conductor assembly of a circuit interrupter after an opening stroke includes a streamlined latch that omits components commonly prone to damage during latching operations in existing latching assemblies. The disclosed latching assembly comprises a fixed latch block, a driven latch rotatably coupled to the latch block, and a pivoting hammer with a square pin positioned to always be engaged with the driven latch. The latching assembly is structured to be engaged by a switch shaft once an opening stroke is initiated. When the latching assembly engages, the hammer square pin pushes the driven latch into engagement with a shelf formed in the switch shaft, which prevents the switch shaft from rebounding after the opening stroke. Rebounding is further prevented due to the hammer being structured to be biased toward the open state once the driven latch has engaged the switch shaft shelf.
