The present invention relates to an integrated interlock device of an air circuit breaker, and more particularly, to an integrated interlock device of an air circuit breaker capable of using different types of interlock devices in an integrated manner in case of using two or more air circuit breakers connected to each other, and a method of using the same. The integrated interlock device of an air circuit breaker includes: a mounting plate (30) installed at part of a cradle or a switchboard; a bi-directional lever (40) rotatably installed at the mounting plate, having a first arm and a second arm which are toward different directions on the basis of a first rotation shaft, and moved in a connected state to a main shaft of a circuit breaker body; a unidirectional lever (50) rotatably installed at the mounting plate in a spaced state from the bi-directional lever, having a third arm which is toward one direction on the basis of a second rotation shaft, and moved in a connected state to an off lever of the circuit breaker body; and first to third cables (81, 82, 83), including sheaths and core members, configured to transmit a power in a connected state to the first to third arms, respectively.
