ABSTRACT:
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).
