1. A reset lockout mechanism for a circuit breaker, the reset lockout mechanism comprising:
a conductive path between line and load phase terminals, the conductive path having an open configuration and a closed configuration, and the reset lockout mechanism is configured to prevent the conductive path from moving to the closed configuration when a predefined condition exists;
a linkage positioned to move between an open position and a closed position;
a rocker selectively engageable with the linkage, wherein the rocker has an ON position corresponding to an ON state of the circuit breaker and an OFF position corresponding to an OFF state of the circuit breaker;
an armature selectively engageable with the rocker; and
a solenoid including a plunger, the plunger being operatively coupled to the armature;
wherein the plunger is movable between a first position and a second position.
