ABSTRACT:
A circuit breaker includes a housing; separable contacts housed by the housing; an operating mechanism, for moving the separable contacts between a closed position and an open position thereof, having a first position and a second position corresponding to the open position; a latching and releasing mechanism for latching the operating mechanism in the first position thereof and for releasing the operating mechanism to the second position thereof; a rotatable trip bar rotatable in a first rotational direction and a second rotational direction for unlatching the latching and releasing mechanism; a sensing mechanism for sensing an electrical condition associated with the separable contacts and for moving the trip bar in the second rotational direction in order to unlatch the latching and releasing mechanism, release the operating mechanism to the second position thereof, and move the separable contacts to the open position thereof; and an adjustable bias spring for biasing the trip bar in the first rotational direction.
