ABSTRACT A door interlock includes first and second, normally inter-coupled plates mounted to a circuit breaker for sliding movement between respective first and second positions. The first plate includes an aperture through which a circuit breaker trip push-button normally extends, thereby sustaining the plates in their first positions where the second plate serves as a catch for the door of the breaker enclosure. Upon depression of the trip push-button the breaker is tripped and the plates may be conjunctively slid to their second positions where the first plate sustains the depressed condition of the pushbutton to ensure that the breaker is open, while the second plate clears the enclosure door such that it can be opened. If desired, the intercoupling between the plates may be defeated, such that the second plate can be slid to its second position independently of the first plate, and the door may be opened while the circuit breaker is closed. The first plate can also be padlocked in a. third position where it is effective to sus- tain depression of the trip pushbutton and inhibit opening of the enclosure door.
