A circuit breaker (100) includes a housing (102), a first trip mechanism (120), and a second trip mechanism. The first trip mechanism (120) includes a first plunger (134) selectively spring biased to a first plunger extended position from a first plunger retracted position. The second trip mechanism (122) includes a second pin (154) supported on the first plunger (134) and configured to be driven by the first plunger (134) to a second pin extended position that follows the first plunger extended position. A second lever (160) fixed with respect to the second pin (154) is configured to be driven by the second pin (154) to a second lever extended position. A second plunger (162) is selectively spring biased to a second plunger extended position, and when the second pin (154) is driven to the second pin extended position, the second lever (160) follows the second pin (154) to the second lever extended position to allow the second plunger (162) to be in the second plunger (162) extended position.
