Electrical Switching Apparatus and Opening Assembly Therefor Having Engagement Lug
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.
