A motorized racking operator for racking a circuit breaker into and out of electrical switchgear is disclosed. The racking operator includes a motor, an On-Off control in signal communication with the motor, an anti-rotation bracket securely attached to the motor, and a latch. The motor has a drive shaft with an end configured to operably engage with a receiving end of a racking shaft. The latch serves to removably secure the motor and bracket to the circuit breaker such that the motor and bracket move in unison with the circuit breaker in response to the motor driving the racking shaft to rack the circuit breaker into and out of the switchgear. The anti-rotation surface of the bracket engages with a surface of the circuit breaker to prevent rotation of the motor in response to the motor applying a torque to the racking shaft.
