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.
