    Abstract: A circuit breaker includes a shielding component having an external portion which defines a space external to the circuit breaker housing and covers a vent in the circuit breaker housing to direct gasses and debris from the vent to an outlet. The external portion also prevents insertion of the circuit breaker into a breaker box closer than the distances defining the space. This can have the advantage of preventing arcing from the breaker contacts to the breaker box. The external portion may also prevent insertion of the circuit breaker into a breaker box such that a vent in the circuit breaker housing is blocked. In some implementations, the shielding component contains an internal portion which extends into the circuit breaker housing and is disposed to impede debris generated by contact arcing, or other debris, from entering the mechanism of the circuit breaker.
