19 52,285 ABSTRACT OF THE DISCLOSURE A drawout and interlock assembly for manually inserting a low-voltage molded case circuit breaker into positive electrical engagement with the plug-in power terminals of a distribution switchboard panel and then withdraw the breaker into a disconnected-test position is disclosed. The drawout position of the assembly comprises a pair of guide rails and a pair of drive rails that are secured to the back of the circuit breaker housing and cooperate with a pair of support rails and a drive means that are secured to the stationary power blocks of the switchboard panel to effect a sliding telescopic interfitting of parts that permits the circuit breaker to be manually racked into connected and disconnected-test positions in an efficient reliable manner with a minimum number of parts. Automatic tripping of the breaker before it is connected to or disconnected from the switchboard panel is achieved by a toggle-actuated interlock lever that engages a depressable interlock button on the back of the circuit breaker housing when the drive means is moved by an operating handle.
