Abstract
A circuit breaker incorporates a collapsible telescoping linkage installed between its control handle and electrical contacts. The collapsible telescoping linkage is normally locked in an extended position to open and close the contacts as the control handle is moved between its off and on positions. The circuit breaker includes an electromagnetically operated armature operable in response to an overload condition to unlock the collapsible telescoping linkage to allow the linkage to collapse and instantaneously break the contacts. Thereafter, when the control handle moves to its off position, the linkage is locked in its extended position so that upon subsequent movement of the control handle to its on position the circuit breaker is automatically reset.
