The present invention provides an arrangement for actuation of TAC actuator having different pivot axis than Latch link of the circuit breaker. The arrangement for actuation in a circuit breaker comprises: an actuator comprises an actuator pivot point and a trip alarm contact interface point;a latch link having an actuator interface feature and a latch link pivot point; a mechanism trip plate. The actuator pivotally connected to the latch link to facilitate actuation of an auxiliary contact by rotation of the actuator with the latch link, thereby pushing the trip auxiliary contact actuator of the auxiliary contact to activate the auxiliary contact in trip condition.
