1. A mechanism-operated assembly for a circuit breaker, comprising:
a drive assembly arranged within the circuit breaker and fixedly attached to an output shaft of the circuit breaker;
a drive pin hingedly attached to the drive assembly within the circuit breaker, the drive pin extending through a guide slot formed in a housing of the circuit breaker;
a drive plate slidably mounted adjacent to the circuit breaker and in contact with the drive pin; and
a drive arm pivotably mounted at one end and engaged at an opposite end with the drive plate;
wherein changing an operational state of the circuit breaker rotates the output shaft, causing the drive assembly to rotate, thereby moving the drive pin within the guide slot and sliding the drive plate in a direction that pivots the drive arm from a first position to a second position.
