Abstract
A circuit breaker assembly includes a housing, a trip mechanism, a vent channel, and a chamber. The trip mechanism is positioned within the housing can causes a movable contact to separate from a second contact in response to detection by the circuit breaker assembly of an electrical fault. The vent channel is formed in the housing and positioned to exhaust gas and debris produced as the movable contact separates from the second contact during the electrical fault to an aperture in the housing. The chamber has a chamber housing coupled to the housing adjacent the aperture such that the chamber receives the gas and debris exiting the aperture.
