An actuator for a circuit breaker in a switchgear includes a housing, an actuating shaft, at least one armature, and at least three windings. The housing is defined with a bore along a longitudinal axis of the housing. The bore of the housing facilitates displacement of the actuating shaft within the bore. The actuating shaft is connectable to an electrical component of a circuit breaker. On selective energization of the at least three windings, the at least one armature connected to the actuating shaft is configured to be displaced within the bore to facilitate multiple stage-based configuration of the actuator.
