34 ABSTRACT OF THE DISCLOSURE A molded case circuit breaker includes an improved system for internally venting gaseous arc products to control the internal gas pressure increase and expansion during an arc interruption. The system includes a first gas expansion chamber disposed proximate to a stationary electrical contact of a pair of separable electrical contacts of the circuit breaker and a second gas expansion chamber disposed proximate to an electrically insulating arc chute barrier that is positioned at an end of an elongated arc chute remote from said stationary electrical contact. The arc chute barrier and the stationary electrical contact are physically configured to effect the rapid internal venting of gaseous arc products to the first and second chambers.
