    Abstract: An opening assembly is provided for an electrical switching apparatus having a housing, separable contacts enclosed by the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a poleshaft. The opening assembly includes a spring link comprising a first portion structured to be pivotably coupled to the poleshaft, and a second portion disposed generally opposite of the first portion. A number of opening springs each include a stationary end coupled to the housing, and a movable end coupled to the second portion of the spring link. The spring link is movable between an open position, wherein the opening springs bias the spring link and poleshaft to maintain full separation of the separable contacts, and a closed position, wherein the opening springs either do not bias the poleshaft or bias the poleshaft with a low level of torque.

    Abstract: A trip assembly is for an electrical switching apparatus. The electrical switching apparatus 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 poleshaft and a trip D-shaft. The trip assembly comprises: a yoke assembly comprising a yoke member and a trip pin coupled to the yoke member, the yoke member being structured to be coupled to the poleshaft; and a link assembly comprising a linking member, the linking member being structured to cooperate with each of the trip pin and the trip D-shaft. When the yoke member moves in response to a trip condition, the linking member is structured to transmit movement of the yoke member into movement of the trip D-shaft.

    Abstract: A debris barrier is for an electrical switching apparatus. The electrical switching apparatus includes separable contacts and an arc chute. The separable contacts generate debris when tripping open in response to an electrical fault. The arc chute has a plurality of splitter plates each having an edge portion and a distal portion located opposite and distal the edge portion. The debris barrier includes a first leg, a second leg, and a middle portion connecting the first leg and the second leg. The middle portion is coupled to one of the separable contacts. At least one of the first leg and the second leg has a first barrier portion and a second barrier portion extending therefrom. The first barrier portion is located proximate the distal portion. The second barrier portion extends from the first barrier portion toward the edge portion in order to redirect the debris toward the edge portion.
