Abstract
A reset lockout mechanism for a circuit breaker includes a linkage, a rocker, an armature, a solenoid, and a plunger. The linkage is positioned to move between an open position and a closed position. The rocker is selectively engageable with the linkage. The armature is selectively engageable with the rocker. The plunger is supported by the solenoid and operatively coupled to the armature. The plunger is movable between a first position and a second position.
Claims22
A circuit breaker comprising:
- a line phase terminal;
- a load phase terminal;
- a line neutral terminal;
- a conductive path formed between the line and load phase terminals, the conductive path having an open configuration and closed configuration;
- a linkage configured to move the conductive path between the open configuration and the closed configuration;
- and
- a reset lockout mechanism configured to prevent the conductive path from moving to the closed configuration when a predefined condition exists, the reset lockout mechanism including:
- a rocker selectively engageable with the linkage, the rocker configured to move the linkage between an open position and a closed position;
- and
- an armature selectively engageable with the rocker to maintain the conductive path in the open configuration when the predefined condition exists.
