A drawer type circuit breaker comprises a drawer base and a circuit breaker body, wherein the circuit breaker body is rocked into and out of the drawer base, so that a main circuit of the circuit breaker body and the drawer base is switched on and switched off; a safety baffle is provided between the drawer base and the circuit breaker body to block a drawer base busbar or a bridge type contact of the drawer base; and a front-rear displacement device for the safety baffle to move toward a movement direction of the drawer base is provided on the safety baffle and the drawer base. According to the drawer type circuit breaker of the present invention, the front-rear displacement device is provided on the safety baffle and the drawer base, the safety baffle is displaceable front and back, and the drawer base busbar may penetrate out of the safety baffle. The bridge contact can be mounted either on the drawer base or on the body, such that the mounting position of the bridge type contact is more flexible, and the connection of the main circuit is more stable and reliable.
