<p>An opening assembly (100) is provided for an electrical switching apparatus (200) having a housing (202), separable contacts (204) enclosed by the housing (202), and an operating mechanism (206) for opening and closing the separable contacts (204). The operating mechanism (206) includes a poleshaft (208). The opening assembly (100) includes a spring link (102) comprising a first portion (104) structured to be pivotably coupled to the poleshaft (208), and a second portion (106) disposed generally opposite of the first portion (104). A number of opening springs (110) each include a fixed end (112) fixedly coupled to the housing (202), and a movable end (114) coupled to the second portion (106) of the spring link (102). The spring link (102) is movable between an open position, wherein the opening springs (110) bias the spring link (102) and poleshaft (208) to maintain full separation of the separable contacts (204), and a closed position, wherein the opening springs (110) do not bias the poleshaft (208).</p> |
