CIRCUIT BREAKER ENCLOSURE HAVING INTEGRATED PASS-THROUGH

An enclosure of a circuit breaker that includes an interior region and a pass-through. The interior region can be sized to house a circuit interrupter and a dielectric insulating medium. The pass-through can include a pathway having a first open end and a second open end, the first and second open ends being in direct fluid communication with each other through the pathway. The first and second open ends can be secured to the enclosure such that the pass-through is integral to the enclosure, such as, for example, being part of a monolithic structure or constructed to form a unitary body. Additionally, the pathway may not be in direct fluid communication with the interior region of the enclosure. Further, the pass-through can be offset from, or extend directly into, the interior region of the enclosure.
