Abstract
A line terminal for a circuit breaker includes a body forming two opposing legs and a third leg. The opposing legs are configured to form a passage for receiving a stab from a panel board. The two opposing legs are biased toward each other, and each of the opposing legs has a convex surface facing the passageway for engaging and maintaining alignment of the stab. A fixed contact is attached to the third leg. The fixed contact connects to a moveable contact of a circuit breaker. An arc runner is connected to the third leg and at least partially encloses a perimeter of the fixed contact.
