Abstract
A molded case circuit breaker support and a circuit breaker enclosure are arranged with air transfer slots and passages to promote chimney effect cooling of the circuit breaker components. The slots in the circuit breaker support direct ambient cooling air onto the circuit breaker terminals while the passages through the enclosure direct the ambient air flow from the bottom to the top of the enclosure.
