A circuit breaker includes a first electrical contact and a second electrical contact moveable between an open state and a closed state; an armature, wherein movement of the armature from a first position to a second position initiates the first electrical contact and the second electrical contact to move from the closed state to the open state; a first electromagnetic device configured to move the armature from the first position to the second position in response to being energized by a first signal; and a second electromagnetic device configured to move the armature from the first position to the second position in response to being energized by a second signal and in response to generation of the first signal and the first electrical contact and the second electrical contact still being in the closed state. Other circuit breakers and methods of operating circuit breakers are disclosed.
