An arc member is provided for an electrical switching apparatus. The electrical switching apparatus includes an operating mechanism for opening and closing separable contacts, and an arc chute disposed proximate the separable contacts to attract an arc generated thereby. The separable contacts include a stationary contact and a movable contact. The stationary contact has an edge, which is disposed in a plane. The arc member includes an arc element disposed between the stationary contact and the arc chute. The arc element has first and second portions and first and second arc attractors. The first arc attractor extends outwardly from the first portion toward the plane of the edge of the stationary contact to draw the arc from the separable contacts to the arc member. The second arc attractors, which are disposed on the second portion of the arc element, direct the arc into the arc chute.
