摘要： A vented case is provided for an electrical switching apparatus including an arc chute structured to attract and dissipate an arc. The arc produces an ionized gas. The vented case includes at least one housing member comprising an interior, an exterior, a first end, a second end disposed generally opposite and distal from the first end, and an intermediate portion extending between the first end and the second end. The vented case also includes at least one vent structured to discharge the ionized gas from the interior of such housing member to the exterior of such housing member. Such vent includes a plurality of venting passages, each extending from proximate the arc chute within the interior to the exterior. An electrical switching apparatus is also disclosed.
