A circuit breaker including a housing, separable contacts, a cradle rotatably mounted within the housing, an alarm switch mounted within the housing, and an interface lever disposed between the cradle and the alarm switch. The cradle is adapted to rotate about a first axis in a first direction when the circuit breaker moves to a tripped position in which the separable contacts are separated from one another. The alarm switch includes an actuation lever movable in an actuation direction, wherein movement of the actuation lever in the actuation direction causes the alarm switch to activate an alarm device electrically connected thereto. When the cradle rotates in the first direction, the cradle exerts a first force against the interface lever that causes the interface lever to exert a second force against the actuation lever that causes the actuation lever to move in the actuation direction.
