PURPOSE: A drawer type circuit breaker is provided to achieve improved use convenience and safety, while reducing manufacturing costs. CONSTITUTION: A drawer type circuit breaker comprises a main body(101); an off button(102) mounted on the main body; an off link(103) arranged in such a manner that a contact surface(103a) of the off link contacts the rear surface of the off button and the off link rotates centering from a fixed point(103b) of the off link, wherein the off link has a first protrusion(103c) and a second protrusion(103d); a lock member(110) having a portion coupled with the first protrusion of the off link, and which reciprocates in a predetermined section in accordance with the rotation of the off link and permits a lead-in/out handle(116) to be inserted into the lock member such that the lock member temporarily controls the lead-in/out operation of the circuit breaker by using the lead-in/out handle; an off-lever(104) coupled to an off-lever shaft mounted on the main body, and which has an end which contacts the second protrusion of the off link so as to rotate together with the off-lever shaft; a lock plate(105) for rotating an on-lever so as to apply an electricity to a circuit; an on-lever pusher for preventing rotation of the lock plate when the lock plate moves to an end of the on-lever pusher and permitting rotation of the lock plate when the lock plate moves to the other end of the on-lever pusher; and an on button mounted on the main body so as to rotate the on-lever pusher.
