Abstract: A contact arm for a circuit breaker includes a body extending along a body axis between a first end and a second end. The body includes an interior surface, an exterior surface, and a fin extending between the interior surface and the exterior surface. The body defines a fin opening adjacent the fin. The fin opening extends between the interior surface and the exterior surface. The interior surface defines a substantially hollow interior. A body opening is located at the first end in fluid communication with the interior. Air flows through the body opening, into the interior, and from the interior out through the fin opening to reduce a temperature of the contact arm.
