Abstract:
A link assembly is for an electrical switching apparatus, such as a circuit breaker. The circuit breaker includes a housing, separable contacts enclosed by the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a movable contact arm. The separable contacts comprise a stationary contact and a movable contact. The movable contact is disposed on the movable contact arm. The link assembly includes a pivot assembly pivotably coupled to the movable contact arm, a link element pivotably coupled to the pivot assembly, and a biasing element, such as a spring. A first end of the spring is coupled to the link element, and a second end of the spring is coupled to the circuit breaker housing.
