An automatically operating interlock prevents connection of an electrical device within a cabinet unless the cabinet door is closed. The interlock is particularly useful for circuit breakers contained within arc-resistant cabinets. The interlock includes a spring-biased locking plate reciprocating between a locked position wherein the locking plate resists movement of the levering-in locking plate, and an unlocked position wherein the locking plate permits movement of the levering-in locking plate. The locking plate is spring-biased towards its locked position, and is pushed from its locked position to its unlocked position when the cabinet door is closed. Access to the hex drive of the levering-in rod is thereby resisted when the cabinet door is open.
