A breaker includes a housing ( 10 ) having two terminals ( 11, 12 ), two bars ( 17, 18 ) electrically coupled to the terminals ( 11, 12 ), an arm ( 30 ) supported in the housing ( 10 ) and movable to engage with the bars ( 17, 18 ) to electrically couple the terminals ( 11, 12 ) together. A control device ( 4 ) may control the arm ( 30 ) to engage with the bars ( 17, 18 ), and includes a lever ( 50 ) to maintain the arm ( 30 ) in engagement with the bars ( 17, 18 ). A spring ( 33 ) may bias the arm ( 30 ) away from the bars ( 17, 18 ), and another spring ( 53 ) may be engaged with the lever ( 50 ) to bias and disengage the lever ( 50 ) from the arm ( 30 ).
