Abstract: Systems and methods for indicating an operational status of a circuit breaker within a switchgear comprise providing a mechanism-operated control (MOC) assembly arranged within a housing of the circuit breaker. A drive plate is slidably mounted on a wall of the switchgear adjacent to the MOC assembly. A drive arm is pivotably mounted at one end on the wall of the switchgear, the drive arm engaged at an opposite end thereof with the drive plate. A status indicator is disposed on the wall of the switchgear, wherein changing an operational state of the circuit breaker mechanically operates the MOC assembly to slide the drive plate in a direction that pivots the drive arm from a first position to a second position, the first and second positions of the drive arm being visible externally of the switchgear through the status indicator.

Abstract: A high-voltage multipolar circuit breaker including a first chamber for receiving gases, in communication with a first arc quenching chamber, and including a first aperture for exhausting gases to the exterior of the casing, the aperture being provided with a first downstream filtering device. The circuit breaker furthermore includes at least one second chamber for receiving gases, in communication with at least one second arc quenching chamber of another pole of the circuit breaker, the chamber itself being equipped with a second upstream device for filtering gases, the second chamber for receiving gases including a second aperture for exhausting gases to the exterior of the casing, the chamber being provided with a second downstream filtering device, the first chamber for receiving gases and the second chamber for receiving gases being separated fluidically one from the other by an impermeable wall.
