Circuit breaker trip mechanism assembly

A circuit breaker comprising:

• a housing;
• a first trip mechanism disposed in the housing, the first trip mechanism including a first plunger disposed within the housing and selectively spring biased to a first plunger extended position from a first plunger retracted position;
• and
• a second trip mechanism disposed in the housing, the second trip mechanism including:
• a second pin in physical contact with the first plunger and configured to be driven by the first plunger to a second pin extended position that follows the first plunger extended position, and to a second pin retracted position that follows the first plunger retracted position;
• a second lever pivotally fixed with respect to the second pin and configured to be driven by the second pin to a second lever extended position that follows the second pin extended position, and to a second lever retracted position that follows the second pin retracted position;
• a second plunger disposed within the housing and selectively spring biased to a second plunger extended position;
• a third set of electrical contacts fixed with respect to the second plunger;
• and
• a fourth set of electrical contacts fixed with respect to the housing,
• wherein the second plunger defines a second plunger retracted position in which the third set of electrical contacts directly contact the fourth set of electrical contacts so as to make electrical contact, and the second plunger defines the second plunger extended position in which the third set of electrical contacts and the fourth set of electrical contacts are spaced from one another so as to create an open circuit;
• and
• wherein when the second pin is driven to the second pin extended position by the first plunger, the second lever follows the second pin to the second lever extended position to allow the second plunger to be in the second plunger extended position, thereby causing the third set of electrical contacts to be spaced from the fourth set of electrical contacts.
