Abstract: A circuit interrupter with end-of-life protection has four components: 1) a control circuit to activate an electromagnetic unit upon detecting a predetermined condition; 2) a fuse coupled between the control circuit and the power supply; 3) an end life sensing circuit coupled to the control circuit; and 4) an end life indicating circuit coupled to the end life sensing circuit and the power supply. The end life sensing circuit includes a light emitting device and a light sensitive device controlled by the light emitting device. The end life indicating circuit includes a visual indicator to indicate that the circuit interrupter reaches the end of its life. Another circuit interrupter with end-of-life protection has three components: 1) a control circuit to activate an electromagnetic unit upon detecting a predetermined condition; 2) a fuse coupled between the control circuit and the power supply; and 3) an end life sensing and indicating circuit coupled to the control circuit.

Abstract: A circuit interrupter comprises a pair of fixed contact strips, a pair of movable contact strips, a reset component, a movable component, and a tripping component that contains a reset contact. Each of the fixed contact strips has a fixed contact. Each of the movable contact strips has a fixed end and a movable end which has a movable contact arranged for contacting one of the corresponding fixed contacts.

Abstract: A circuit interrupter comprises a pair of fixed contact strips, a pair of load contact strips, a pair of movable contact strips, a reset component, a movable component, and a trip component that contains a reset contact. Each of the fixed contact strips has a fixed contact. Each of the load contact strips has a load contact. Each of the movable contact strips has a fixed end and a movable end. The movable end of each movable contact strip is split into an inner sub-strip and an outer sub-strip. Each movable end has a first movable contact disposed on the inner sub-strip arranged for contacting one of the corresponding load contacts and a second movable contact disposed on the outer sub-strip arranged for contacting one of the corresponding fixed contacts. The movable component, disposed to sustain the movable ends of the movable contact strips, allow the inner sub-strips and the outer sub-strips to rest on different horizontal planes.
