A circuit breaker support saddle is assembled automatically from three plastic support pieces without welding or using separate fasteners to secure the pieces together. The metal circuit breaker support rails are positioned onto blocks integrally formed on the two outermost pieces to mechanically hold the pieces together as a single unit. The circuit breaker stab support busses are retained within elongated slots formed within the outer edges of the central support piece.

Circuit breaker support saddle for automated assembly

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.
