ABSTRACT:
A linking assembly is provided for an electrical switching apparatus, such as a circuit breaker. The linking assembly includes a hatchet having first and second edges and an arcuate portion extending therebetween. The hatchet moves between a latched position in which the first edge engages a D-shaft, and an unlatched position in which the hatchet pivots with respect to the D-shaft to unlatch the linking assembly. A cradle includes first and second opposing ends and an intermediate portion disposed therebetween. A latch plate, which is pivotally coupled to the housing, includes a protrusion that cooperates with the hatchet. A latch link is disposed between and is pivotally coupled to the cradle and the latch plate. A toggle assembly includes first and second linking elements coupled between the circuit breaker poleshaft and the cradle.
