Claim:
A circuit breaker assembly, comprising: a housing; a trip mechanism within the housing for causing a movable contact to separate from a second contact in response to detection by the circuit breaker assembly of an electrical fault; and a chamber having at least two separate and spaced apart baffles therein, wherein the housing and the chamber form at least one path originating in the housing and extending through the chamber and towards an exhaust opening in the chamber, the at least one path being positioned to exhaust gas and debris produced as the movable contact separates from the second contact during the electrical fault from the housing, the at least one path having a plurality of sections along which the gas and the debris change directions at least twice due to the at least two baffles before exiting the exhaust opening, and wherein the chamber causes at least some of the exiting gas and debris to travel along at least a first portion of the at least one path in a first direction and along a second portion of the at least one path in a second direction that is opposite the first direction.
