Summary:An automatically operating interlock device 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 brake bar controlling the position of a brake. The brake bar is biased so that it pulls the brake against one of the wheels of the circuit breaker, thereby preventing movement of the circuit breaker towards its rear, connected position. Closing the door causes the door to push against the brake bar, thereby causing the brake bar to pivot the brake away from the wheel. The circuit breaker may then be moved rearward towards this connected position.
